Chipmunk tools currently support monochrome, 8-bit, 16-bit, and 24-bit displays. The 16-bit and 24-bit display modes are only known to work on the PC architecture (X11 under Linux and OS/2); see this document for more details on the current status of color support.
By default, the Chipmunk tools select a color mode using these rules:
The user can force the color mode of a Chipmunk tool by setting the environment variable LOG_COLOR to be the string bw or 8bit or 16bit or 24bit.
Manually placing and sizing the mylib and newcrt windows can quickly become tedious. The Chipmunk tools can automatically size and place these windows. To enable this feature, you'll need to add information to an X initialization file in your home directory, typically named .Xresources. Three resources are implemented for the Chipmunk tools:
By default, the mylib window uses the 6x10 font and the newcrt window uses the 8x13 font. On some X servers, these fonts may not be available. These resources change the default fonts:
Alternatively, the default fonts may be specified at compile-time in the psys Makefile.
After changing the .Xresources file, run xrdb -merge .Xresources to activate the new behaviors. If this command does not update your X server, you should exit and restart the X server.
My .Xresources for my color Sun IPC machine is as follows:
My .Xresources for my HP 712/80 machine, which has a higher-resolution monitor, is
Some versions of the NX server do not have the default Chipmunk fonts available. The .Xresources entries below remedy the situation:
These features were added to the Chipmunk tools by Jim Clark at Harvard University, Tor Sverre Lande at IFI, and Michael Godfrey at Stanford University. Thanks to Derek Woolverton for documentation updates.
