XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) NAME xfig - Facility for Interactive Generation of figures under X11 SYNOPSIS xfig [options] [file] DESCRIPTION Xfig is a menu-driven tool that allows the user to draw and manipulate objects interactively under the X Window System. It runs under X version 11 release 4 or higher and requires a two- or three-button mouse. file specifies the name of a file to be edited. The description of objects in the file will be read at the start of xfig. When using a two-button mouse use the <Meta> key and the right button at the same time to effect the action of the middle button. Xfig is available via anonymous ftp from ftp.x.org in /contrib/applications/drawing_tools/xfig. The TransFig package is used when printing or exporting the output from xfig. It is automatically called by xfig as a back-end processor to produce various types of output: LaTeX fig2dev -L latex translates xfig to LaTeX picture environment commands which can be processed along with other LaTeX commands. Metafont fig2dev -L mf produces Metafont output. PostScript fig2dev -L ps produces an Encapsulated PostScript output. IBM-GL fig2dev -L ibmgl produces a IBM-GL (HP/GL) output. Pic fig2dev -L pic produces a pic output. PiCTeX fig2dev -L pictex produces PiCTeX output. This contains macros that can be used with the PiCTeX environment under TeX or LaTeX. Others fig2dev has options for these other languages: box, epic, eepic, and eepicemu. The TransFig package is available via anonymous ftp from ftp.x.org in /contrib/applications/drawing_tools/transfig. OPTIONS -help Print all command-line options for xfig and quit. - 1 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) -L[andscape] Make xfig come up in landscape mode (10.5" x 8"). This is the default; however as the orientation is stored with Fig files, when you load a Fig file the orientation will change as required. This is only true for files of version 3.0 or higher. -P[ortrait] Make xfig come up in portrait mode (8.5" x 9"). See note about landscape mode. -bol[d] font Cause the font used for displaying the file name and confirmation messages to be font (default = 8x13bold). -butt[on] font Cause the font used for most buttons to be font (default = 6x13). -but_[per_row] number Specify the number of buttons wide the mode panel should be. This is useful in conjunction with the -pheight parameter to reduce the canvas height for small screens. -cbg color Use color as the background color for the canvas. If you want to set the background of everything in xfig (e.g. menus, etc.) use the general -bg option. -cfg color Use color as the default color for objects. If you want to set the foreground of everything in xfig (e.g. menus, etc.) use the general -fg option. -deb[ug] Turn on debugging mode. Prints various debugging messages like font names etc. -dep[th] Choose depth of visual desired. Your server must support the desired visual and depth chosen. Use xdpyinfo to see what visuals and depths are supported. See also the -visual option. -do[ntswitchcmap] Prevents xfig from switching to a private colormap if there aren't enough colors available in the default colormap. See also -max_image_colors. -e[xportLanguage] language Specifies the language to be used for when exporting a fig file. Choices are: - 2 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Name Language ------------------------------------------- box LaTeX box (figure boundary) latex LaTeX picture epic LaTeX picture + epic macros eepic LaTeX picture + eepic macros eepicemu LaTeX picture + eepicemu macros pictex PiCTeX macros ibmgl IBMGL (or HPGL) eps Encapuslated PostScript ps PostScript pstex Combined PS/LaTeX (both PS and LaTeX parts) textyl Textyl special commands tpic TPIC pic PIC mf MF (MetaFont) acad ACAD (AutoCad slide) pcx PCX png PNG gif GIF* jpeg JPEG (JFIF) tiff TIFF ppm PPM (portable pixmap package) xbm X11 Bitmap xpm X11 Pixmap (XPM3 package) *xfig must be compiled with USEGIF to have GIF export. See README file for patent warning. ------------------------------------------- -fl[ushleft] Set the print option to print the figure flush left. The default is to center the figure on the page. -geom[etry] +X+Y Do not use the -geometry option or resource to size xfig. It may only be used to position the xfig window. Use -pwidth and/or -pheight to specify the canvas size in inches or centimeters. -iconG[eometry] +X+Y Specifies the position for the icon. -inc[hes] Make inches the unit of choice (default). -internalBW width Use lines of width width between all buttons and panels (default = 1). -inv[erse] - 3 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Use inverse video (white on black). -k[eyFile] compose-key-file Use compose-key-file instead of CompKeyDB for compose (meta) key database. If there are no ``/''s in the name, the file must reside in the xfig library directory, $XFIGLIBDIR, usually /usr/local/lib/X11/xfig. If there are any ``/''s in the name it is taken as is (not relative to $XFIGLIBDIR). If there is a leading ``~/'' in the string then the ``~'' is expanded to the user's home directory. -lat[exfonts] Start xfig with LaTeX font selection. Normally, the PostScript fonts are available as the default. This flag selects the LaTeX fonts to start. -le[ft] Change the position of the side panel window to the left of the canvas window. This is the default. -mag[nification] mag Set export and print magnification in %. -max[_image_colors] numcols Limit the number of colors used for EPS, GIF, JPEG, PCX or XPM images to numcols (default 64). -me[tric] Make centimeters the unit of choice. After xfig is started you may change the units from metric to imperial or vice versa from a popup menu available by pressing mouse button 3 in the units box where the two rulers meet. -mo[nochrome] Use black and white only. -mu[ltiple] Sets multiple page mode for print or export. See also -single. -nor[mal] font Cause the font used for the message window to be font. This font is also used on the canvas when the selected font is not available in an X11 font (default = 6x13). -nos[calablefonts] Disables use of the X11R5 or OpenWindows scalable fonts. You might want to use this for debugging. -not[rack] - 4 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Turn off cursor (mouse) tracking arrows. -pa[per_size] size Set the initial paper size for Export and Print. Choices are Letter (8.5" x 11"), Legal (8.5" x 14"), Ledger ( 17" x 11"), Tabloid ( 11" x 17"), A (8.5" x 11"), B ( 11" x 17"), C ( 17" x 22"), D ( 22" x 34"), E ( 34" x 44"), A4 (21 cm x 29.7cm), A3 (29.7cm x 42 cm), A2 (42 cm x 59.4cm), A1 (59.4cm x 84.1 cm), A0 (84.1 cm x 118.9cm), B5 (18.2cm x 25.7cm) Note that this doesn't affect the size of the drawing canvas. Use the -pheight and -pwidth options for that. -ph[eight] height Make the xfig canvas height high (where height is either cm or in, depending on the -metric setting). -pw[idth] width Make the xfig canvas width wide (where width is either cm or in, depending on the -metric setting). -ri[ght] Change the position of the side panel window to the right of the canvas window (default: left). -sc[alablefonts] Allows use of the X11R5 or OpenWindows scalable fonts (this is the default). If the scalable fonts aren't available xfig will automatically switch to non-scaling fonts. -sh[owallbuttons] Show all the xfig indicator buttons instead of only those relevant to the current drawing mode. Normally, the buttons line width, area-fill, grid mode, text size, etc. are only visible when they are relevant to the current drawing mode. The -showallbuttons option makes all of the indicator buttons visible at all times. This takes up more screen real estate, but allows the user to see all settable parameters. -si[ngle] - 5 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Sets single page mode for print or export. This is the default. See also -multiple. -spec[ialtext] Start xfig with the special text mode for text objects. Special text means that special characters in the string are not specially processed but are passed directly to LaTeX. This is most useful for writing LaTeX equations. If this flag is not set, then the backslash character '\' is changed to the \backslash command, a brace '{' is turned into a brace command \{, etc. -spel[lcheckcommand] command Use command for the external spell checking program when using the spell check/search/replace popup. The string command should include the string ``%s'' which is replaced by a temporary filename. Default is ``spell %s''. -startfi[llstyle] stylenumber Set the starting fill style for area fill (-1 to 21). -startfo[ntsize] pointsize Set the default font size for text objects (default = 12pt). -startg[ridmode] modenumber Set the starting grid mode (0 to 3). Mode 0 is no grid. In imperial (inches) mode, grid mode 1 is 1/4 inch, mode 2 is 1/2 inch and mode 3 is 1 inch. In metric mode, grid mode 1 is 5mm, mode 2 is 1cm and mode 3 is 2cm. -startla[texFont] font Set the starting font name for LaTeX fonts. -startli[newidth] width Set the starting line width. -startpo[snmode] modenumber Set the starting point positioning mode (0 to 4) In imperial (inches) mode, positioning mode 0 is ``any'', mode 1 is 1/16 inch, mode 2 is 1/4 inch, mode 3 is 1/2 inch and mode 4 is 1 inch. In metric mode, mode 0 is ``any'', mode 1 is 1mm, mode 2 is 5mm, mode 3 is 10mm and mode 4 is 20mm. -startp[sFont] font Set the starting font name for PostScript fonts. -startt[extstep] stepsize Set the starting text step. -ta[blet] - 6 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Specifies that xfig should use the input tablet instead of the mouse for drawing. You must have the XInputExtension in your X server and an input tablet for this to work. Also, you must modify the Imakefile to include the USETAB and TABLIB variables. -tr[ack] Turn on cursor (mouse) tracking arrows (default). -users[cale] scale Set the multiplier for displayed line lengths etc. This factor is multiplied by the actual length, radius or diameter of the object currently being drawn on the canvas. It is useful for making scale drawings, where e.g. 1 inch = 1 foot (userscale = 12.0) or 1cm = 1m (userscale = 100.0). -useru[nit] units The units string is printed with the length information when drawing objects. For example if the userscale = 1.0 and the userunit = ft then a line which is 3 inches long on the canvas would be displayed as ``length = 3 ft'' when it is being drawn. After xfig is started you may change the userscale and the userunit from a popup menu available by pressing mouse button 3 in the units box where the two rulers meet. -visual visualname Use visualname as the visual for xfig. The names are TrueColor (case is not important), StaticColor, DirectColor, StaticGray, GrayScale and PseudoColor. xfig uses the default visual unless this is specified. Your server must support the desired visual. Use xdpyinfo to see what visuals and depths are supported. See also the -depth option. -zoom zoomscale Set the starting zoom scale. GRAPHICAL OBJECTS The objects in xfig are divided into primitive objects and compound objects. The primitive objects are: ARC, CIRCLE, ELLIPSE, POLYLINE, POLYGON, PICTURE, BOX, ARC-BOX, CLOSED SPLINE, OPEN SPLINE, and TEXT. A primitive object can be moved, rotated, flipped vertically or horizontally, scaled, copied, aligned within a compound object or erased. The TEXT primitive may not be flipped. The attributes of any primitive object can be edited using a popup panel (discussed below), so you can, for instance, set the position of an object manually. A compound object is composed of primitive objects. The primitive objects that constitute a compound can not be individually modified, but they can be manipulated as an entity; a compound can be moved, rotated, flipped vertically or horizontally, scaled, copied or erased. - 7 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) A compound that contains any boxes or arc-boxes may only be rotated by 90 degrees. Objects may overlap other objects according to their ``depth''. Objects with larger depth number are obscured by objects with smaller depth. Regular polygons may be created using a special drawing mode, but a general POLYGON is created as a result, which may then be modified, i.e. the individual vertices may be moved if desired. Conversions between POLYLINE , POLYGON , OPENSPLINE and CLOSEDSPLINE are achieved by the CONVERT tool. DISPLAY REGIONS There are ten regions in the xfig window: the command region, top ruler, side ruler, drawing mode, editing mode, filename, message, mouse function indicator, canvas (drawing area), and indicator region with buttons to show and change settings such as line thickness, line style, color, etc. (The mouse function indicator region was inspired by the UPS debugger from the University of Kent.) The drawing and editing mode regions may be placed (together) to the left or right of the the canvas region (default: left). In addition, when the mouse passes over certain buttons or regions there are ``balloons'' (messages) which popup to indicate the function of the area under the mouse. These may be turned on and off by clicking on the button labelled ``Balloons'', to the right of the message region. There is a check mark indicating their state. COMMAND PANEL FUNCTIONS Quit Exit from xfig, discarding the figure. If the figure has been modified and not saved, the user will be asked to confirm the action, by clicking mouse button 1 on a confirm/cancel popup menu. The accelerator <Meta>q will also perform this function. This and all other accelerators are defined in the app-defaults file and may be changed if desired. Port/Land Change shape of xfig canvas from/to portrait/landscape. Note: the canvas will automatically change to the portrait/landscape configuration specified in Fig files of version 3.0 or higher when loading those files. New Delete all objects from the canvas window and erase current file name to make a new drawing (may be undone). The accelerator <Meta>n will also perform this function. If you attempt to save the new figure using the keyboard accelerator <Meta>s or with mouse button 3 on the File button the popup file menu will appear for you to enter a file name. You may use the accelerator <Meta>d to delete all the objects - 8 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) from the canvas and retain the current file name. Undo Undo the last object creation, deletion or modification. The accelerator <Meta>u will also perform this function. If an undo of a Paste or file Merge is done, any user-defined colors in the figure pasted in or the file just merged will NOT be undefined. Redraw Redraw the canvas. There are also two accelerators which do a redraw - <Meta>r and <Ctrl>l. Paste Paste the object previously copied into the cut/paste file into the current figure (at its original position). The accelerator <Meta>t will also perform this function. File Pressing mouse button 3 on this button invokes Save function without popping up the file panel. Before the figure is saved the original file is first renamed with the suffix ``.bak'' appended. This provides a backup file. Mouse button 1 or <Meta>f pops up a panel which contains several file-related functions. Do not use this function for importing images (picture objects). See the ``IMPORTING PICTURE OBJECTS'' section. Current Filename This is read-only AsciiTextWidget which contains the filename that will be used to write output to a file if there is no name specified in the Filename panel. Filename This is an editable AsciiTextWidget which contains the filename selected either by clicking on a filename from the Alternatives list or by typing a name in directly. Pressing return in the Filename window will Load the file and copy the name to the Current Filename widget. Note that xfig will automatically uncompress or gunzip any files that have .Z, .z or .gz as the suffix. (File) Alternatives Pressing mouse button 1 on a filename in the file alternatives window will select that file by copying the filename into Filename window. Pressing return in this window will Load the file specified in the Filename window (if any) or the Current Filename widget. - 9 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Filename Mask A wildcard mask may be typed into this editable AsciiTextWidget to restrict the search of filenames to a subset ala the ls command. Pressing return in this window will automatically rescan the current directory. This string may be set by setting the X toolkit resource Fig*file_panel*mask*string. Current Directory This is an editable AsciiTextWidget which shows the current directory. It may be modified by the user to manually set a directory name. When return is pressed in this window the directory specified is scanned for files matching the Filenamemask, if any. The ~ (tilde) character may be used to specify a user's home directory, ala unix shell tilde expansion. (Directory) Alternatives Pressing mouse button 1 on a directory name in the directory alternatives list will do a ``change directory'' to that directory. Pressing mouse button 3 in either the file or Directory Alternatives window will do a ``change directory'' to the parent directory. Load/Merge figure offset These two editable AsciiTextWidgets allow one to load or merge a figure with an offset on the canvas. The figure will be offset by the amounts specified (in Fig units) in the X and Y panels. A negative value in the X offset will shift the figure to the left, and a negative value in the Y offset will shift the figure up. Home Pressing this button will change the directory to the $HOME directory of the user. Rescan Pressing this button or <Meta>r will rescan the current directory. Cancel Pressing this button or <Meta>c will pop down the File panel without making any changes to the directory or file name. - 10 -Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Save Pressing this button or <Meta>s will save the current contents of the canvas in the file specified in the Filename window if any, or the name specified in the Current Filename if the former is empty. If the filename being saved is different from the current figure name and that file already exists a confirmation popup menu will appear asking the user to confirm or cancel the save. If there is a filename in the Filename window it is copied to the Current Filename window. The current Export directory is updated to the current File directory when Save is pressed. Before the figure is saved the original file is first renamed with the suffix ``.bak'' appended. This provides a backup file. Load Pressing this button or <Meta>l will clear the canvas of any current figure and read the figure from the filename specified in the Filename menu item if any, or the name specified in the Current Filename if the former is empty. The figure will be offset by the amounts specified (Fig units) in the X and Y load/merge offset widgets. If there is a figure currently on the canvas and any modifications have been made to it and not saved, a popup query window will first appear asking if the user wishes to discard the current figure or cancel the Load operation. The current Export directory is updated to the current File directory when Load is pressed. Note that xfig will automatically uncompress or gunzip any files that have .Z, .z or .gz as the suffix. A popup message window will appear and diagnostic messages will be written if xfig changes any ``illegal'' object values to legal values. For example, older versions of xfig were lax about initializing unused parts such as depth, and would produce very large, random values. Xfig now will ``clean up'' bad values and inform you when it does so. Also, if you read in an older file format, xfig will inform you that it is converting it to the current format for that version of xfig. This window can be popped down by clicking the mouse button on the Dismiss button. - 11 -Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Merge Read Pressing this button or <Meta>r will read the figure from the filename specified in the Filename window if any, or the name specified in the Current Filename if the former is empty, and merge it with the figure already shown on the canvas. The figure will be offset by the amounts specified (Fig units) in the X and Y load/merge offset widgets. Any user-defined colors in the file being merged will be renumbered if necessary to unique values so as not to conflict with any user-defined colors already defined. There is no comparison of the color values of the existing user-defined colors with the colors being merged in so there may be identical colors with different numbers. See Load above for a description of the popup message window. Export Will let you export the figure to an output file in one of several formats. Pressing mouse button 3 on this button invokes Export function without popping up the export panel. Mouse button 1 or <Meta>e pops up a directory browser widget and a menu with several export-related functions: Magnification This is an editable AsciiTextWidget which contains the magnification to use when translating figure to the output language. The default is 100%. Fit to Page Pressing this button will set the magnification so that the figure will just fit the current paper size with no less than a 1/2 inch margin. Fig Size: This label shows the figure size at the current magnification. It is updated when the panel is popped up and when the user changes the magnification and shows the size in inches or cm depending on the current units. Paper Size This is a pulldown menu which allows you to select the paper size for printing. The choices are: Letter (8.5" x 11"), Legal (8.5" x 14"), - 12 -Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Ledger ( 17" x 11"), Tabloid ( 11" x 17"), A (8.5" x 11"), B ( 11" x 17"), C ( 17" x 22"), D ( 22" x 34"), E ( 34" x 44"), A4 (21 cm x 29.7cm), A3 (29.7cm x 42 cm), A2 (42 cm x 59.4cm), A1 (59.4cm x 84.1 cm), A0 (84.1 cm x 118.9cm), B5 (18.2cm x 25.7cm) Orientation This button will toggle the output orientation between Landscape (horizontal) and Portrait (vertical). The default orientation is the same as the mode that xfig was started with, or the orientation in the Fig file when loading a Fig file of version 3.0 or higher. Justification This window will only be sensitive when the language selected is ``ps'' (PostScript). You may choose that the figure is flush left or centered in the output file. Pages With this pulldown menu you can select whether the figure should be exported as a single page or multiple pages. The multiple page option would only be useful if the figure is larger than the current physical paper size. Export Offset These two editable AsciiTextWidgets allow one to export a figure with an offset. The figure will be offset by the amounts specified (in inches or cm) in the X and Y panels. A negative value in the X offset will shift the figure to the left, and a negative value in the Y offset will shift the figure up. These offsets are in addition to any centering done with the centering option. Margin Width For the bitmap type export languages such as GIF, JPEG, etc. an optional white border may be added around the figure by specifying the margin width (in pixels). - 13 -Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Language The translation language to use for xfig output. The default is specified in the resource Fig.exportLanguage and is Encapsulated PostScript as xfig is distributed. Several languages are available; PostScript, Encapsulated PostScript, LaTeX, TPIC, PIC, Textyl, IBM/GL (HP/GL), MetaFont, and serveral bitmap formats; GIF, JPEG (JFIF), PNG, PCX (PC Paintbrush), ACAD (AutoCad slide), TIFF (no compression), PPM (Portable Pixmap package), XBM (X11 monochrome bitmap) and XPM (XPM3 package, producing color pixmaps). Image quality (%) For JPEG(JFIF) export, this entry will appear, and you may select the quality factor for the JPEG image. Valid values are 1 to 100%. The default quality of 75% seems to be fine for figures containing only solid objects (no images) and adequate for figures containing imported images (GIF, JPEG, etc.). Transparent Color For GIF export, this menu button will appear and you may choose that one of the colors in the figure is ``transparent'', meaning that for those GIF viewers that support transparent color (Netscape, for example) that color will not appear in the figure. Instead, the background of the viewer will show through in place of that color The default is ``None'' (no transparent color). Default Output Filename This is read-only AsciiTextWidget which contains the filename that will be used to write output to a file if there is no name specified in Output File. The default is the figure name plus an extension that reflects the output language used, e.g. myfigure.ps if PostScript is the current language used. If the file already exists a confirmation popup menu will appear asking the user to confirm or cancel the save. Output Filename This is an editable AsciiTextWidget which contains the filename to use to write output to a file. Pressing return in this window will Export the file and copy the name to the Default Output Filename widget. If the file already exists a confirmation popup menu will appear asking the - 14 -Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) user to confirm or cancel the save. (File) Alternatives Pressing mouse button 1 on a filename in the file alternatives window will select that file by copying the filename into Filename window. Pressing return in this window will Export the file and copy the name to the Default Output Filename widget. Filename Mask A wildcard mask may be typed into this editable AsciiTextWidget to restrict the search of filenames to a subset ala the ls command. Pressing return in this window will automatically rescan the current directory. This string may be set by setting the X toolkit resource Fig*export_panel*mask*string. Current Directory This is an editable AsciiTextWidget which shows the current directory. It may be modified by the user to manually set a directory name. When return is pressed in this window the directory specified is scanned for files matching the Filenamemask, if any. It is automatically updated to follow the current File directory when a File Load or Save is done. The ~ (tilde) character may be used to specify a user's home directory, ala unix shell tilde expansion. (Directory) Alternatives Pressing mouse button 1 on a directory name in the directory alternatives list will do a ``change directory'' to that directory. Pressing mouse button 3 in either the file or Directory Alternatives window will do a ``change directory'' to the parent directory. Home Pressing this button will change the directory to the $HOME directory of the user. Rescan Pressing this button or <Meta>r will rescan the current directory. - 15 -Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Cancel Pressing this button or <Meta>c will pop down the Export menu without doing any print operation. Export Pressing this button or <Meta>e will write (export) the figure to the file using the selected language. If the file already exists, a confirmation window will popup to ask the user to confirm the write or cancel. Pressing return in the Output Filename window will also Export the file. Print Pressing mouse button 3 on this button invokes Print to Printer function without popping up the print panel. Pressing the Shift key and mouse button 3 invokes the Print to Batch function. Pressing mouse button 1 or <Meta>p pops up a menu with several print-related functions: Magnification This is an AsciiTextWidget which contains the magnification to use when translating figure to the output language. Fit to Page Pressing this button will set the magnification so that the figure will just fit the current paper size with no less than a 1/2 inch margin. Fig Size: This label shows the figure size at the current magnification. It is updated when the panel is popped up and when the user changes the magnification and shows the size in inches or cm depending on the current units. Paper Size This is a pulldown menu which allows you to select the paper size for printing. See the Export menu for the paper sizes. Orientation This button will toggle the output orientation between Landscape (horizontal) and Portrait (vertical). The default orientation is the same as the mode that xfig was started with, or the orientation in the Fig file when loading a Fig file of version 3.0 or higher. - 16 -Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Justification This button will bring up a sub-menu from which you may choose center or flush left to justify the figure on the page. The default is flush left. Pages With this pulldown menu you can select whether the figure should be printed as a single page or multiple pages. The multiple page option would only be useful if the figure is larger than the current physical paper size. Printer This is an AsciiTextWidget which contains the printer to use if output is directed to a printer. The name of the printer may be set setting the X toolkit resource Fig*printer*string. If no resource is set, the environment variable PRINTER is used. Print Job Params This is an AsciiTextWidget which into which you may put any extra command-line parameters that your lpr or lp program needs for printing. If the meta sequence %f appears in the string the current figure name will be substituted. It may appear more than once. This may be set using the resource Fig*job_params*string. Figures in batch This indicator shows how many figures have been put in the batch file for printing Dismiss Pressing this button or <Meta>c will pop down the Print menu. Print FIGURE/BATCH to Printer Pressing this button or <Meta>p will send the current figure (or the batch file if it is has any figures in it) to the printer, by passing it through fig2dev to convert it to PostScript then to the unix lpr (on BSD equivalent Unixes) or lp (on SYSV systems) program. If the batch file is printed by this button then it is removed after printing. The message in the button changes to reflect whether the batch file will be printed (when there are any figures in the batch file) or the current figure. - 17 -Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Note that the figure that is printed is what you see on the canvas, not necessarily the figure file. I.e., if you haven't saved the figure since the last changes, the figure from the canvas is printed. Xfig writes the figure to a temporary file to do this. The name of the file is XFIGTMPDIR/xfig-printPID, where XFIGTMPDIR is the value of the environment variable by that name and PID is the process ID of xfig. If the environment variable XFIGTMPDIR is empty or not set, the /tmp directory is used. Print FIGURE to Batch Pressing this button or <Meta>b will append the figure (in PostScript form) to a batch file. The Print to Printer button will send the batch file to the printer. Clear Batch Pressing this button or <Meta>x will erase the accumulated figures from the batch file. INDICATOR PANEL COMMAND DESCRIPTIONS The indicator panel contains buttons to set certain drawing parameters such as line thickness, canvas grid, rotation angle etc. All of the buttons use the same mouse buttons for setting values. Pressing mouse button 1 on the indicator will pop up a panel in which either a value may be typed (e.g. for a line thickness) or the mouse may be clicked on one of several buttons (e.g. for grid style or font name). For those that expect a value, pressing return in the value part of the window will set the new value and pop down the menu. Pressing mouse button 2 on an indicator will decrement the value (e.g. for line thickness) or cycle through the options in one direction (e.g. font names), while pressing mouse button 3 will increment the value or cycle through the options in the other direction. ZOOM SCALE The canvas zoom scale may be set/increased/decreased with this button. The zoom scale is displayed within the zoom button. Ruler, grid and linewidth are scaled, too. Pressing mouse button 2 will decrease the zoom factor by 1.0 unless it is less than 1.0 already in which case it will reduce to the nearest 0.25. Pressing mouse button 3 will increase the zoom factor by 1.0 unless it is less than 1.0 in which case it will increase it to the nearest 0.25. Pressing the control key and mouse button 3 together will set the zoom scale to 1. The figure may also be zoomed by defining a zoom rectangle by pressing the Control key and mouse button 1 together. This will define one corner of the zoom rectangle. Move the mouse and click mouse button 1 again to define the opposite corner of the zoom rectangle. - 18 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) GRID MODE With this button the user may select no grid, 1/4 inch (5mm in metric mode) grid 1/2 inch (10mm) grid, or 1 inch (20mm). POINT POSITION This button controls the coarseness of object placement on the canvas. The options are exact (on pixel) placement, 1/16 inch (1mm in metric mode), 1/4 inch (5mm), 1/2 inch (10mm) or 1 inch (20mm). This allows the user to easily place objects in horizontal or vertical alignment. This also restricts which objects may be ``picked up'' by the mouse when editing. If a corner of an object is not positioned on the canvas on a multiple of the point positioning resolution you may not be able to pick it. If this happens, a black square will temporarily appear above the mouse cursor. This square will also appear anytime the user tries to pick a nonexistent object. ROTATION ANGLE The rotation angle for rotating objects may be set/increased/decreased with this button. Note that not all objects may be rotated, and certain objects may only be rotated by certain angles. Pressing mouse button 2 will decrease the angle in steps of 15 degrees, while mouse button 3 will increase the angle the same amount. To select other angles, press mouse button 1 and enter the angle in the popup menu. DEPTH The depth at which new objects will be created may be set/increased/decreased with this button. NUMBER OF POLYGON SIDES The number of sides used in creating a REGULAR POLYGON is set with this button. NUMBER OF COPIES The number of copies to make when doing a COPY & ROTATE function on an object. Each copy will be rotated an additional ROTATION ANGLE angle from the previous. NUMBER OF X (or Y) COPIES The number of copies to make in the X (or Y) direction when doing a COPY function on an object. SMART-LINKS MODE This button controls the smart-links mode. When turned on, lines which link box-like objects together (henceforth called links) are treated specially when one of the box-like objects is moved or copied. For a copy, the link is also copied. When set to MOVE mode, the end point of the link which touches (or is very near) the perimeter of the box is moved with the box so that the - 19 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) box and the end point remain linked. When set to SLIDE mode, the end segment of the link slides so that the box remains linked and the angle of the end segment is maintained. This is useful for keeping the last segment of a link horizontal or vertical. (At the moment, smart-links only work for the MOVE and COPY functions and only works for POLYLINE links and box-like objects. Another limitation at the moment is that if both ends of a link touch the box being operated on, only one end of the link will be adjusted.) VERTICAL ALIGN This sets the vertical alignment mode for the ALIGN button in the editing mode panel. The choices are no vertical alignment, align to top edge, middle or bottom edge of compound, distribute the centres or edges evenly, or abut the vertical edges together. The HORIZONTAL ALIGN and VERTICAL ALIGN indicator settings are used together to align objects inside a compound or in canvas. HORIZONTAL ALIGN This sets the horizontal alignment mode for the ALIGN button in the editing mode panel. The choices are no horizontal alignment, align to left edge, middle or right edge of compound, distribute the centres or edges evenly, or abut the horizonaal edges together. The HORIZONTAL ALIGN and VERTICAL ALIGN indicator settings are used together to align objects inside a compound or in canvas. ANGLE GEOMETRY The following settings are available to restrict the drawing angle of line segments in POLYLINES, POLYGONS and SPLINES. UNRESTRICTED Allow lines to be drawn with any slope. This is the default setting. LATEX LINE Allow lines to be drawn only at slopes which can be handled by LaTeX picture environment lines: slope = x/y, where x,y are integers in the range [-6,6]. LATEX VECTOR Allow lines to be drawn only at slopes which can be handled by LaTeX picture environment vectors: slope = x/y, where x,y are integers in the range [-4,4]. MANHATTAN-MOUNTAIN Allow lines to be drawn in the horizontal, vertical or diagonal direction only. - 20 -Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) MANHATTAN Enforce drawing of lines in the horizontal and vertical direction only. The name Manhattan comes from the horizontal/vertical look of the Manhattan (New York City) skyline. MOUNTAIN Enforce drawing of only diagonal lines. The name comes from the pointed shape of mountains. FILL STYLE This button allows the user to select the area fill darkness (grey scale or color intensity) or fill patterns for all objects except TEXT and PICTURE, or to turn off area fill altogether. There are 21 ``shades'' going from black to full saturation of the fill color, and 21 more ``tints'' from full saturation + 1 to white. In addition, there are 16 patterns (currently only available for PostScript, GIF, JPEG, PNG, PCX, ACAD, TIFF, PPM, XPM and XBM output): 30 degree left-leaning diagonal lines, 30 degree right-leaning diagonal lines, 30 degree crosshatch, 45 degree left-leaning diagonal lines, 45 degree right-leaning diagonal lines, 45 degree crosshatch, bricks, circles horizontal lines, vertical lines, 90 degree crosshatch, fishscales, small fishscales, octagons, horizontal ``sawtooth'' and vertical ``sawtooth''. PEN COLOR This button is used to select one of 32 standard colors for the borders of objects, or one of the user-defined colors FILL COLOR This button is used to select one of 32 standard colors or user-defined color to fill objects with if they have a fill style. Pressing mouse button 1 on either the fill or pen color buttons will popup an extended color panel, allowing - 21 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) the user to select either a standard color or a user- defined color from menus. The 32 standard colors are black, yellow, white, gold, five shades of blue, four shades of green, four shades of cyan, four shades of red, five shades of magenta, four shades of brown, and four shades of pink. To select one of the standard colors either click mouse button 1 on the desired color and either press Return or click mouse button 1 on the ``Ok'' button. The latter step will pop down the color panel. You may also double click mouse button 1 on the desired color to select it and pop down the color panel in one step. To add a user-defined color press mouse button on the ``Add Color'' button in the ``User Defined Colors'' section. User defined colors are assigned values sequentially starting from 32 for a maximum of 512 colors. A user color may be deleted by pressing mouse button 1 on the color box to select it and then pressing the ``Del Color'' button. The last color deleted may be undeleted by pressing the ``UnDel Color'' button. To edit a user color first select the color square by pressing mouse button 1 on the desired square. A solid or dashed line will be drawn around the box to show that it is selected. Then choose the color either by using the RGB (red, green, blue) or the HSV (hue, saturation, value) sliders or by typing a hexadecimal value into the window under the pen or fill color boxes representing the red, green and blue components (00 to FF). If the latter is used, typing carriage return in the hexadecimal window will set the color. Additionally, there is a button above each of the RGB sliders which when activated will ``lock'' two or more sliders together at their current setting and allow you to increase or decrease their values together with the ``lock'' slider. If the user color being edited was just created, a dashed line will be drawn around the box instead of a solid line to indicate that it is new. The color that is currently in the pen or fill boxes will be copied into the user color cell for modification. In this way you may start with a standard color or other user color - 22 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) and modify it from there. The user color is said to be ``defined'' when any of the sliders is moved or a carriage return is typed into the hexadecimal window. This will be shown by a solid line being drawn around the square instead of dashed. The pen or fill color choice is activated when the panel is popped up by the respective button in the indicator panel, but you may switch to editing the other color by pressing either the ``Edit Pen'' or ``Edit Fill'' button. Note that TransFig supports color output for PostScript. On monochrome screens the objects are created with the selected color, but black (or white) is used to draw the objects on the canvas. LINE WIDTH The width of lines may be selected with this button. Zero width lines may be drawn for the purpose of having filled areas without outlines. LINE STYLE The choices for line style are solid, dash, dot, dash- dot, dash-dot-dot and dash-dot-dot-dot. Once created, a dashed or dotted line may be edited to change the length of dashes or the spacing of dots respectively. The dash length and dot gap can be changed from the default using the popup menu. JOIN STYLE Lines may be joined with a miter, rounded or bevel joint. This is only used for POLYLINE or POLYGON objects. CAP STYLE The ends of lines may be capped with butt, round or projecting cap. This is only used for POLYLINE, SPLINE or OPEN ARC objects. ARROW MODE This button selects the auto-arrow mode for drawing lines. The options are no arrow heads, backward- pointing arrow head, forward-pointing arrow head or both. If one or both arrow head modes are turned on, then arrow heads are automatically drawn when drawing POLYLINE, OPEN SPLINE or OPEN ARC objects. ARROW TYPE There are four types of arrows which may be filled with - 23 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) white or the object color. BOX CURVE The radius of the corners on ARC-BOX objects may be set with this button. TEXT JUSTIFICATION The adjustment of text may be set to left, center or right justification. TEXT SIZE The text size may be set/increased/decreased with this button. The default is 12 points. TEXT STEP The interline spacing of text may be set/increased/decreased with this button. The number displayed gives the multiple of the font height that will be placed between lines on hitting <return>. The default is a factor of 1.2 times the current font size. TEXT FONT This button allows a selection of 35 fonts available for most Apple PostScript printers. There are two buttons at the top of the menu. The cancel button pops down the menu without changing the current font. The use latex fonts will switch the menu to the LaTeX font choices. When the LaTeX font menu is up, besides a cancel button there is a button to switch back to the PostScript fonts. The name of the font is printed in the font itself so that one may see what that font looks like. If a corresponding X11 font exists, new text is created on the canvas using that font. xfig uses the size of X11 font closest to that selected by the font size button. If the X11 font doesn't exist, xfig uses the font selected by the -normal option. To abort selection of a font, click mouse button 1 on cancel. TEXT FLAGS This button displays the current setting of the text flags. You may use mouse buttons 2 and 3 to step back and forth through the three flag settings: Hidden, Rigid and Special. To change any of the flags you must use mouse button 1 to popup a menu from which you may change any or all of the flags. The Hidden flag is used for figures that will be used with LaTeX and is applicable only to the display of the document in xfig. It means that the text itself is not - 24 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) shown onscreen, but only the string ``''. This is to keep long sequences of LaTeX formatting commands from making the screen messy and hard to read. The default for the Hidden flag is off. The Special Special flag means that special characters in the string are not specially processed but are passed directly to LaTeX. If this flag is not set, then the backslash character '\' is changed to the \backslash command, a brace '{' is turned into a brace command \{, etc. The default for the Special flag is off unless xfig is started with the command-line parameter -specialtext (resource specialtext). The Rigid attribute forces text to remain the same size even if inside a compound object that is scaled up or down. The default is off. DRAWING AND EDITING MODE PANELS Icons in the drawing and editing mode panel windows represent object manipulation functions, modes and other drawing or modification aids. Manipulation functions are selected by positioning the cursor over the icon representing the desired drawing/editing function and clicking mouse button 1. The selected icon is highlighted, and a message describing its function appears in the message window. The hilighting remains on until another function is selected. DRAWING MODE PANEL COMMAND DESCRIPTIONS The drawing mode panel contains buttons used to create the various xfig objects. Once the drawing mode is selected, the object is created by moving the mouse to the point on the canvas where the object is to be placed and pressing and releasing mouse button 1. After that the mouse is moved to the second point and mouse button 1 is again pressed for the next point. For those objects which may have more than two points (e.g. a line), mouse button 1 may be pressed for each successive point, and mouse button 2 must be pressed to finish the object. To create a single point using the POLYLINE button, press and release mouse button 2. If the cap style is rounded, the point object will be a filled circle. Newly created points may be deleted by pressing the shift key and mouse button 1. For the ARC object, which requires exactly three points mouse button 1 is used for all three points. At any time mouse button 3 may be pressed to cancel the creation of the object. ARC Create an arc. Specify three points using mouse button 1. The first and last points will form the endpoints of the arc and the second specifies any point on the arc. There are two types of arcs, open and pie-wedge. - 25 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) BOX Create rectangular boxes. Start by clicking mouse button 1 on any corner of the desired box and finish with the same mouse button on the diagonally opposite corner of the box. ARC-BOX Create rectangular boxes with rounded corners. Start and finish with mouse button 1 in the same way as BOX. The radius of the corners is selected by the BOX CURVE button. CIRCLE Create circles by specifying their radii or diameters. Click mouse button 1 on the center of the circle and drag the mouse until the desired radius or diameter is attained. Click mouse button 1 again to finish the circle. ELLIPSE Create ellipses using the same procedure as for the drawing of circles. IMPORTING PICTURE OBJECTS This has been changed from the previous (2.1) version to be more generic, allowing GIF files, JPEG (JFIF) files, PCX (PC Paintbrush), X11 bitmap (monochrome) files and X11 pixmap (XPM3) color files in addition to Encapsulated PostScript files to be imported. Compressed (.Z) and gzipped (.z or .gz) files are also handled. You must have the XPM3 libraries installed to use the XPM import/export features. See the README and Imakefile files. A Floyd-Steinberg dithering is applied to color images for monochrome displays. For EPS files, xfig will attempt to use Ghostscript to generate a color image if xfig is running on an color display. Ghostscript must be compiled with with the ``pcx256'' and ``pbmraw'' drivers. The pbm driver is used when you run xfig on a monochrome display and the pcx256 driver is used on a color display. Ghostscript is available from prep.ai.mit.edu. A neural network color allocation scheme is used when the number of colors for all the color images on the canvas exceeds the lesser of the number of free colorcells or the value in the resource Max_image_colors (command-line parameter -max_image_colors). Whenever a new color image is added to the canvas, the colors for all the images on the canvas are reallocated and the images are redrawn. No reallocation is done when images are deleted from the canvas. Click mouse button 1 on any corner for the PIC object and finish by clicking mouse button 1 again on the diagonally opposite corner. The EDIT popup panel will appear and the file name of - 26 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) the PIC object may be entered. After pressing DONE or APPLY (see the description of the EDIT panel for the difference between the DONE and APPLY buttons) the bitmap part of the PIC object will appear in the box just created. If no PIC file is available yet or no name is entered or in the case of an Encapsulated PostScript file there is no preview bitmap pressing DONE will pop down the edit panel and the word <empty> or the PIC file name will remain in the PIC box. Later, when the name of the PIC file is known or the file is available, you may re-read the PIC file using the popup edit panel and the bitmap part of the PIC file will replace the name in the box. If you want the original size of the PIC object, press the ``Use orig size'' button and the eps bitmap will enlarge or shrink to the size specified in the preview bitmap of the PIC file. If you want the PIC object to be approximately the size of the rectangle specified with the mouse but want the aspect ratio to be same as the original, press either ``Shrink to orig'' or ``Enlarge to orig'' buttons. You must press the APPLY button to see these effects. The Screen Capture button will unmap the xfig windows, allowing you to capture a rectangular section of the screen to a GIF* file, which becomes the current import file. After pressing the Screen Capture button you press and release mouse button 1 at one corner of the area of the screen you want to capture, drag out the rectangle and press and release mouse button 1 to finish. You may cancel the operation by pressing either of the two other mouse buttons. The filename given to the capture file is the base of the figure name plus the time in seconds since 00:00:00 GMT, Jan 1, 1970 (from the Unix time() call), e.g. myfigure_828065129.gif. *If xfig was compiled without the USEGIF symbol then the capture file is in PCX format (PC Paintbrush) with the suffix ``.pcx''. The Edit Image button will call an external image viewer/editor (see resource Fig.image_editor: in the Fig.ad file) to allow you to edit the current image. The file is reimported automatically after exiting the editor. The xfig windows are automatically unmapped during the call of the editor. The Reread button will cause xfig to re-read the image file in case it has changed. This is useful (e.g.) when you have made changes to the image file in a program external to xfig and you wish to update the imported image. The Browse button which will popup a file browser to allow you to search directories for image files. The default search mask will match *.gif*, *.jpg*, *.pcx*, *.xpm*, *.xbm*, *.ps* and *.eps*. This mask is in the Fig.ad application defaults file. - 27 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) POLYLINE Create polylines (line segments connecting a sequence of points). Enter points by clicking mouse button 1 at the desired positions on the canvas window. Click mouse button 2 to finish. A single point object may be created by simply pressing mouse button 2. If the cap style is rounded, the point object will be a filled circle. Newly created points may be deleted by pressing the shift key and mouse button 1 before pressing mouse button 2. POLYGON The function is similar to POLYLINE except that a line segment is drawn connecting the first and last points entered. REGULAR POLYGON The number of sides is first selected with the NUM SIDES button in the indicator panel. Then mouse button 1 is clicked on the center and the mouse dragged to the desired size. The object may be rotated as it is being created by moving the mouse up or down relative to the starting point. Click mouse button 1 to finish. INTERPOLATED SPLINE The function is similar to POLYLINE except that an open interpolated spline (a spline curve that passes through the control points) is drawn. At least two points must be entered. CLOSED INTERPOLATED SPLINE The function is similar to POLYGON except that a closed interpolated spline is drawn. At least three points must be entered. APPROXIMATED SPLINE The function is similar to POLYLINE except that an open approximated spline (a spline curve that passes through the two boundary points and approximates the shape of the other points) is drawn. At least two points must be entered. CLOSED APPROXIMATED SPLINE The function is similar to POLYGON except that a closed approximated spline is drawn. At least three points must be entered. Note: xfig provides conversion tools to switch between any two of the following objects: polylines, polygones, open interpolated spline, closed interpolated spline, open approximated spline, closed approximated spline. This conversion can be done either globally for the whole object (see LINE<->SPLINE and OPEN<- >CLOSED) or locally for each individual point (see EDIT POINT). TEXT Create text strings. Click mouse button 1 at the desired position on the canvas window, then enter text from the keyboard. Text may be pasted from the PRIMARY cut buffer (xterm cut/paste - 28 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) buffer) by pressing the F18 function key (the Paste key on Sun keyboards) or any key/button defined in the translation table for the canvas. See the default Fig.ad file for example. Text is drawn using the current font, font size and justification settings. A Control-H (backspace) will delete a character to the left of the cursor, while the Delete key or Control-D will delete the character to the right of the cursor. A Control-X will erase all the text to the left of the cursor, while a Control-K will erase all the text to the right of the cursor. The Home key or Control-A will move the cursor to the start of the text, while the End key or Control-E move the cursor to the end of the text. The left arrow key or Control-B move the cursor left one character and the right arrow or Control-F move the cursor right one character. Finish entering/editing text by clicking mouse button 2 or typing the <return> key. If <return> is used, the text pointer automatically moves to the next ``line'', a distance of the font height times the value in the TEXT STEP button, and text input mode is re-entered. To finish text fully, click mouse button 2 or choose any panel button that changes modes (e.g. box, save, etc). To edit text, click on an existing text string with mouse button 1. Insertion of characters will take place at that point. Or, use the popup EDIT mode to modify the text. Eight-bit characters may be entered using the meta (compose) key. For example, to create an ``a umlaut'', press and release either the Meta key, the Alt key or the Compose key, then the letter ``a'', then " (quote). To create a ``c cedilla'', use c followed by comma. When modifying text in the popup eidt panel, only the Compose key will work. The following is a list of all special characters available using the Meta, Alt or Compose keys: Keys Character Name ------------------------------------- !! upside-down exclamation point ?? upside-down question mark C/ cent sign L- British pound OX currency Y- yen __ broken vertical bar SO section "" dieresis CO copyright RO registered trademark _a ordfeminine - 29 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) _o ordmasculine << guillemotleft >> guillemotright -| notsign -- hyphen +- plusminus ^- macron ^* degree ^. periodcentered ^1 onesuperior ^2 twosuperior ^3 threesuperior 14 onequarter 12 onehalf 34 threequarters ** multiply -: division /u mu P! paragraph A` A accent grave A' A accent acute A^ A accent circumflex A~ A accent tilde A" A dieresis A* A ring AE AE a` a accent grave a' a accent acute a^ a accent circumflex a~ a accent tilde a" a dieresis a* a ring ae ae C, C cedilla c, c cedilla D- Eth d- eth E` E accent grave E' E accent acute E^ E accent circumflex E" E dieresis e` e accent grave e' e accent acute e^ e accent circumflex e" e dieresis I` I accent grave I' I accent acute I^ I accent circumflex I" I accent dieresis i` i accent grave i' i accent acute - 30 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) i^ i accent circumflex i" i dieresis N~ N tilde n~ n tilde O` O accent grave O' O accent acute O^ O accent circumflex O~ O accent tilde O" O dieresis O/ O slash OE OE o` o accent grave o/ o accent acute o^ o accent circumflex o~ o accent tilde o" o dieresis o/ o slash oe oe P| Thorn p| thorn ss German ss (s-zed) U` U accent grave U' U accent acute U^ U accent circumflex U" U dieresis u` u accent grave u' u accent acute u^ u accent circumflex u" u dieresis Y' Y accent acute y' y accent acute y" y dieresis ------------------------------------- Note: the two special characters OE and oe are not displayed on the screen, but they are printed by fig2dev. Spell Checking and String Search in Text Objects By pressing h in the canvas area a popup panel will appear which lets you search for strings in the text objects and/or do string replacement and spell checking. The external spell checking program can be specified by the -spellcheckcommand command-line argument (resource Fig.spellCheckCommand). The default is the ``spell'' program. See the -spellcheckcommand description for usage details. The ``Search/Replace/Update'' button will search all text objects for the pattern given in the ``Search:'' entry. A panel pops up showing any matching text objects. If the ``Replace'' button is pressed, the - 31 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) matched pattern in the text objects will be replaced by the string in the ``Replace with:'' entry. If the ``Update'' button is pressed, the matching text objects' attributes will be updated from the current settings in the bottom indicator panel. If the search pattern is empty all text objects will be listed. If the Update button is pressed in that case, all text objects will be updated. EDITING MODE PANEL COMMAND DESCRIPTIONS When a button in the editing mode panel is pressed, any objects that may be affected by that editing operation will show their corner markers. Only those objects may be affected by the particular edit mode. In cases where two edit modes exist for one button, it may be that the corner markers will appear for objects that may be affected by one button but not the other. SELECTING OBJECTS When multiple objects have points in common, e.g. two boxes that touch at one corner, only one object can be selected by clicking on that point. To select other objects, hold down the shift key while pressing mouse button 1: the markers of one object will be temporarily highlighted. By repeatedly clicking mouse button 1 while holding down the shift key, it is possible to cycle through all candidates for selection at that point. To perform the selected action, e.g. deleting one box, click on the point without holding down the shift key. The operation will be performed on the highlighted object. Note: If the mouse is not clicked near enough to an object marker or for whatever reason xfig cannot ``find'' the object the user is trying to select, a black square will temporarily appear above the mouse cursor. GLUE COMPOUND Compound objects are created by first tagging the objects to be compounded and then pressing mouse button 3 to group the tagged objects into a compound object. Single objects are tagged by clicking on them with mouse button 1. A number of objects can be tagged at once by using mouse button 2 to define the upper-left and lower-right corners of a region enclosing the objects. Tagged objects are shown with highlighted markers. Tagged objects which are selected (see the SELECTING OBJECTS section above) will be temporarily unhighlighted. There is currently no special command to tag or untag all of the objects within a figure. You can untag all of the objects by changing from GLUE mode to some other mode (apart from BREAK) and back again. BREAK COMPOUND Break a compound object into separate component parts. Click mouse button 1 on one of the corner markers of the compound object or along one of the imaginary lines defining the compound - 32 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) box. Clicking with mouse button 2 will achieve the same effect but will also tag the component parts for re-gluing into a compound later (although you will not see the tags until you change to the GLUE mode). OPEN COMPOUND Open a compound object temporarily for editing of its components. The compound object selected will be opened, and all other objects in the figure that are not part of the compound will disappear. You can make any changes to objects in the open compound including adding and deleting objects. If you delete all the objects in the compound, the compound will be removed entirely. A popup panel with two buttons appears which lets you close the compound again. The first, labeled ``Close This Compound'' will close the currently open compound. If you open a compound within a compound, you may close all the compounds with one step by clicking on the second button labelled ``Close All Compounds''. After all compounds are closed, the rest of the original figure will reappear. IMPORTANT NOTE: A side effect occurs when you open a compound, delete an object in that compound, close the compound and ``undo'' the delete operation. The object you deleted will reappear but it will not be part of the original compound anymore. You may use this to remove objects from a compound. Conversely, if you delete an object from the canvas, open a compound then undo the delete of the original object, it will now be part of the open compound. SCALE OBJECT Any object may be scaled. If mouse button 1 is pressed on any corner of a BOX or ARC-BOX object, then that object will be scaled proportionally to its aspect ratio. If pressed on an edge then that dimension will be scaled. For other objects only mouse button 2 may be used for scaling; said object will be scaled larger or smaller about its center. Mouse button 2 may be used on boxes too. Text may only be scaled if inside a compound object and then only if its RIGID flag is set to NORMAL (using the popup edit panel). See the TransFig manual for description of text options. ALIGN Align objects. Click mouse button 1 to align objects inside a compound object or mouse button 2 to align all objects on canvas according to the setting in the VERTICAL ALIGN and HORIZONTAL ALIGN indicators. Note that alignment with respect to the canvas doesn't work for distributing or abutting. The choices are the - 33 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) cumulative effect of vertically aligning the objects to the TOP, MIDDLE or BOTTOM edge and horizontally aligning to the LEFT, MIDDLE or RIGHT edge of the compound, along with distributing or abutting the objects vertically or horizontally. MOVE POINT Modify the position of a point of any object except TEXT and COMPOUND objects. For unrestrained movement, click mouse button 1 over the desired point, reposition the point, and click the left button again. For horizontally or vertically constrained move, click mouse button 2 on the desired point and move either horizontally or vertically. Notice that once you choose the direction (horizontal or vertical), movement is constrained in that direction. If, after moving the mouse initially, it is moved in the other direction a greater distance than the current position of the mouse relative to the starting point, then that will be the new constraint direction. In other words if you first move the mouse horizontally one inch (say) then move it vertically 1.3 inches, the direction will switch to vertical until any horizontal motion exceeds 1.3 inches. When the object is positioned where desired, click mouse button 1 to place it if that button was used to start the move (unconstrained), or mouse button 2 (constrained) if that button was used. ADD POINTS Add points to POLYLINE, POLYGON, OPEN SPLINE, or CLOSED SPLINE objects (points of a BOX can not be added or deleted). Note that a REGULAR POLYGON is really an ordinary POLYGON, so adding points to this object is allowed and does NOT keep the polygon regular. MODIFY SHAPE This tool is activated by holding down the Control and Shift keys in any of the EDIT modes. Clicking on a control point of a spline object with mouse button 1 (resp. 3) decreases (resp. increases) the shape factor of the spline at this point, while clicking with mouse button 2 allows the user to cycle quickly between the three basic status of a control point (i.e. approximation, sharp interpolation, smooth interpolation). MOVE Move object. Click mouse button 1 (unconstrained move) or mouse button 2 (constrained move) on any corner marker of the object to be moved. The horizontal/vertical constrained movement (mouse button 2) works exactly as described for MOVE POINT. COPY / CUT TO CUT BUFFER Copy object to canvas or cut buffer. Click mouse button 1 (unconstrained copy) or mouse button 2 (constrained copy) on any corner marker of the object to be copied (for CIRCLE and ELLIPSE objects, mouse may also be clicked on their circumferences). The object will be duplicated and then moved exactly as in MOVE. - 34 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) If the number of X or Y copies is non-zero (from the bottom panel) then that many copies will be made in each respective direction, spaced evenly by the amount of the distance the object is placed from the original object. If mouse button 3 is clicked on an object, that object is copied to the cut buffer for pasting into this or another figure. The file used for the cut buffer is called .xfig in the user's $HOME directory. This allows a user to run two or more xfig processes and cut/paste objects between them. If there is no $HOME, a file is created in a temporary directory called xfigPID where PID is the xfig process ID. The temporary directory used is specified in the environment variable XFIGTMPDIR. If that variable is empty or not set then /tmp is used. DELETE POINTS Delete points from POLYLINE, POLYGON, OPEN SPLINE, or CLOSED SPLINE. Objects (points of a BOX or ARC-BOX can not be added or deleted). Note that a REGULAR POLYGON is really an ordinary POLYGON, so deleting points from this object is allowed and does NOT keep the polygon regular. DELETE Click mouse button 1 on an object to delete the object. Delete a region of the canvas by clicking mouse button 2 and dragging the mouse to define an area of objects to delete. Clicking mouse button 3 on an object will copy the object to the cut buffer (see COPY/CUT TO CUT BUFFER above). EDIT OBJECT Edit settings for an existing object. Click mouse button 1 on the object and a pop-up menu will appear showing existing settings for the object. Some of the menu entries may be changed by typing new values in the appropriate windows. These are editable AsciiTextWidgets and allow cut and paste. Others pop up a sub-menu of multiple choices when pressed and held. Yet others are buttons which toggle a setting on or off (e.g. arrow heads on lines). Press the ``done'' button to apply the changes to the object and finish. Press the ``apply'' button to apply the changes but keep the menu up for further changes. Press the ``cancel'' button to cancel the changes and pop down the menu. The following table shows which settings are used for the different objects. - 35 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Object Angle Fill Line Line Cap Join Box Pen Fill Radius Style Width Style Style Style Curve Color Color ----------------------------------------------------------------------- Arc + + + + + + ----------------------------------------------------------------------- Arc-Box + + + + + + ----------------------------------------------------------------------- Circle + + + + + + + ----------------------------------------------------------------------- Ellipse + + + + + + + ----------------------------------------------------------------------- PIC* + ----------------------------------------------------------------------- Box + + + + + + ----------------------------------------------------------------------- Polygon + + + + + + ----------------------------------------------------------------------- Line + + + + + + + ----------------------------------------------------------------------- Spline + + + + + + ----------------------------------------------------------------------- Text + + ----------------------------------------------------------------------- * Encapsulated PostScript picture objects don't use any of the above attributes. The PostScript image is self-defined. However, X11 bitmap picture objects use the pen color for coloring the bitmap image. EDIT POINT In the EDIT OBJECT mode, click on a control point of a spline with mouse button 3 to call the EDIT POINT window. Set the shape factor either with the scrollbar for arbitrary values, or with the buttons for preset values. Modifications are displayed interactively (the fill pattern, if any, will be temporally removed during the edition, to provide interactive rates). UPDATE By pressing mouse button 1 on an object, the current settings for the indicator buttons (line width, line style, area fill etc.) which have been selected for update are copied into that object. When xfig is started, all indicator buttons which are components of objects are selected for update. To unselect an indicator, click on the update button and click mouse button 1 on the small button in the upper-right corner of the indicator. When that indicator is selected the foreground color (default black) shows. When it is unselected the background color (default white) shows. If mouse button 2 is clicked on an object, the settings in the object that are selected by the indicator buttons are copied into those indicator button settings. Thus, one may copy selected - 36 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) attributes of one object to another. FLIP VERTICALLY Flip the object up/down (mouse button 1) or copy the object and flip it (mouse button 2). Point to part of the object, click the appropriate button. That object will be flipped vertically about that point. Optionally, mouse button 3 may be pressed on the canvas to set an anchor point about which the object will be flipped. A crosshair indicates the anchor point on the canvas. Pressing this button again will unset the anchor point. FLIP HORIZONTALLY Flip the object left/right (mouse button 1) or copy the object and flip it (mouse button 2). Point to part of the object, click the appropriate button. That object will be flipped horizontally about that point. Optionally, mouse button 3 may be pressed on the canvas to set an anchor point about which the object will be flipped. A crosshair indicates the anchor point on the canvas. Pressing this button again will unset the anchor point. ROTATE CLOCKWISE Rotate the object (mouse button 1) or copy and rotate it (mouse button 2) -N degrees (clockwise), where N is the amount set in the rotation indicator button. The object is rotated about the chosen point. Optionally, mouse button 3 may be pressed on the canvas to set a rotation point about which the object will be rotated. A crosshair indicates the rotation point on the canvas. Pressing this button again will unset the rotation point. Not all objects can be rotated, and not all can be rotated at arbitrary angles. For example, BOX, ARC-BOX and PIC objects may only be rotated by 90 degrees. Text objects may be rotated and to any angle. ROTATE COUNTER-CLOCKWISE Rotate the object (mouse button 1) or copy (mouse button 2) +N degrees (counter-clockwise), where N is the amount set in the rotation indicator button. The object is rotated about the chosen point. Optionally, mouse button 3 may be pressed on the canvas to set a rotation point about which the object will be rotated. A crosshair indicates the rotation point on the canvas. Pressing this button again will unset the rotation point. - 37 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) SPLINE <-> LINE Click on mouse button 1 to cycle between polyline, open interpolated spline and open approximated spline when the selected object is open, or between polygon, closed interpolated spline and closed approximated spline when the selected object is closed. Click on mouse button 3 to turn an open object (polyline or open spline) into its corresponding closed object (polygon or closed spline) and vice versa. The closed object is opened at the selected point. ADD/DELETE ARROWS Add or delete arrow heads of OPEN SPLINE, POLYLINE or ARC objects. Add an arrow head by clicking mouse button 1 on the endpoint of the object. Delete an arrow head by clicking mouse button 2 on the endpoint or arrow head. The length and thickness of the arrowheads may be modified using the popup edit panel. PANNING The figure may be panned by clicking mouse button 1, 2 or 3 in the rulers. Clicking mouse button 1 in the top ruler will pan the image to the left by 1/2 inch (1cm in metric mode), adjusted for zoom factor. Clicking mouse button 3 in the top ruler will pan the image right by the same amount. By pressing and holding mouse button 2 the user may drag the ruler by the amount desired, thus panning the image by that amount. If the Shift key is held down while panning the movement is five (5) times the normal rate. The figure is panned up and down in the same way by clicking the mouse in the ruler on the right of the canvas. If the Shift key is held down while panning the movement is five (5) times the normal rate. The figure can be returned to its origin by clicking mouse button 1 in the units (e.g. cm or in) box. The arrow keys may also be used to pan the image and the home key to return the figure to the origin. Also, pressing the Control Key and mouse button 2 will pan the figure to the origin. - 38 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) X RESOURCES and DEFAULTS The overall widget name(Class) is xfig(Fig).

Smith) Because of the difference of some fonts in some X servers and the PostScript fonts on printers, text alignment can be problematic. Not all operations employ smart redrawing of objects which are altered as a by product of the operation. You may need to use Redraw in these cases. Some servers do not allow bitmaps/pixmaps taller than the screen height or wider than the screen width. That is why there is a limit on the width of the top ruler and height of the side ruler. If you need wider/taller rulers AND your server allows bigger pixmaps, you may define MAX_TOPRULER_WD and/or MAX_SIDERULER_HT in your Imakefile in the DEFINES line. For example, to have a maximum top ruler width of 1160 pixels, add -DMAX_TOPRULER_WD=1160 to your DEFINES line in the Imakefile. If the image is panned or the xfig window iconified and de-iconified during the middle of an operation (e.g. while drawing a line), the picture will be distorted. This can be corrected using Redraw after the operation is complete. Corners of object scaled with point positioning in one of the grid modes will not always fall on the grid line, but to the closest pixel. When zoomed very large, the length of dashes in dashed lines will top out at 255 pixels long. This is due to a restriction in X that the dash list is defined by char (255 pixels maximum for a dash). The figure will print correctly, however. When you do a copy/rotate or array place when making multiple copies of objects, only the creation of the last object can be undone with the Undo button. Modifications to text using the popup search/update/replace/spell check panel cannot be undone. See the README file for troubleshooting. SEE ALSO Brian W.

In the 2.1 and older versions of xfig the grid was in multiples of 5 fig units, but they were on intervals 4, 9, 14, 19, etc. When version 3.0 was created, coordinates were simply multiplied by the ratio of the resolutions (1200/80 = 15) so values like 4 became 60 instead of 74 ((4+1)*15 - 1). The JPEG import/export code uses the Independent JPEG Group software (see jpeg/README for details) Image browser, editor and screen capture features by: Jim Daley (jdaley@cix.compulink.co.uk) - 55 - Formatted: August 15, 2000 XFIG(1) XFIG(1) Release 3.2) (Protocol 3.2) Version 3.2: The changes to the version 3.2 file protocol are the addition of the paper size, print/export magnification, single/multiple page indicator and a transparent color name used for GIF export to the header of the file. The other difference in the version 3.2 protocol is the mathematical model used for splines. The new version uses X- splines which allows the user to mix interpolation and approximation points in a same curve. More precisely, it means that an X-spline curve is neither an interpolated spline nor an approximated one, it is BOTH (the behaviour of each point is controlled by one single parameter called ``shape factor''). For additional information about X-splines, see: ``X-Splines: A Spline Model Designed for the End User'' by C. Blanc and C. Schlick, Proceedings of SIGGRAPH'95 http://dept-info.labri.u-bordeaux.fr/~schlick/DOC/sig1.html Caveat: Because previous spline models (quadratic B-splines and Bezier with hidden points) are no longer supported, curves that are present in version 3.1 and older files are automatically converted to X-splines. This translation is only an approximation process. It means that the converted curves are not exactly the same as the original ones. Though they are usually very close, some hand-fitting may be needed in some pathological cases.
