XFIG Users Manual

Global Settings

[Global Settings]

This panel, which may be popped up with the Edit/Global Settings menu item or the keyboard accelerator Meta-G, allows the user to change various settings in xfig.

Track mouse in rulers
This option will cause xfig to show triangular pointers in the rulers which indicate where the mouse is pointing on the canvas.
Show page borders
Xfig will draw a border on the canvas showing the size of the current page setting (see Export or Print) if this option is checked.
Show info balloons. delay(ms)
If this option is checked, xfig pops up a ``balloon'' with information as the mouse passes over buttons or other areas of xfig. E.g.:

The delay tells xfig how long to wait (in milliseconds) after the mouse is positioned on an area before popping up the balloon. The default is 500 ms.
Show lengths on lines
If this is checked, xfig will show the lengths of lines as they are being drawn, thus:

This option may also be turned on or off with the -showlength/-dontshowlength command-line option.
Show vertex numbers
If this is checked, xfig will show the number of each vertex of objects on the canvas thus:

This is probably only useful for debugging of Fig files. This option may also be turned on or off with the -shownums/-dontshownums command-line option.
Allow negative coords
If checked (the default), xfig will allow panning to negative x and y coordinates. This also turns off the query about shifting a figure with negative coordinates when loading a figure.
Draw lines through 0,0
If checked (the default), xfig will draw X and Y axis lines through 0,0 on the canvas
Recently used files
This spinner entry lets the user set the number of recently used files that are kept in the File menu. This is also updated in the user's .xfigrc file in the user's home directory, as are the file names themselves.
Max image colors
This sets the maximum number of colors xfig will attempt to use for imported images. The default is 64 and may also be set with the -max_image_colors command-line option.
Image editor
This is the external program used when the Edit Image button is pressed in the import picture editor. The default is xv . You may use this program to crop/rotate/change colors in etc. your imported image. When you exit from this program xfig will re-import the image.
Spelling checker
This is the external spelling check program which will be called when you use the spell check feature in xfig (Edit/Spell Check, or Meta-K accelerator). The spell program is the default. The %s is necessary to tell xfig to insert the filename into the spell command.
HTML Browser
This is the external web (HTML) browser that xfig will call to view help files. The default is Netscape. The -remote option says to look for a running Netscape and open the pages in that. If none is running, a new one will start. The %f is necessary to tell xfig to insert the filename into the browser command.
PDF Viewer
This is the external PDF (Portable Document Format) viewer that xfig will call to view the xfig tutorial.. The default is acroread. The %f is necessary to tell xfig to insert the filename into the viewer command.
