Raster image to file
Date: Wed, 9 May 90 15:11 EDT
I have no doubt that this has been asked before, but I don't know the
answer and I thought someone out there would. I would like to dump
a color screen to a file in a way analogous to <function-Q>. I would
be happy with any format which could then be redisplayed, but I would
need a description of the format (the files may be displayed on an X
server). Could someone explain how to do this or send the code
To save the color screen as an IMAN image you can use
(COLOR:SAVE-WINDOW color:color-screen :load-or-save :save :where :file :file "fep0:>SCREEN"
or something similar (you can control the format of the resulting image by specifying more
arguments). To hook it up to a function key, you use (TV:ADD-FUNCTION-KEY #\<your-char> '<your-function>).
If you want to integrate it seamlessly into <Function>Q, you'll have to modify some system code, but
that shouldn't be hard; I suspect you can even do it upward-compatibly using ADVISE. Hope that's enough
to get you going...
