If the card provides a device for a program to read RGB values from, yes
it is posible.
For example the following use to work on linuxes that provided a frame
buffered device (direct access to the Xwindow display). The later
linuxes don't seem to provide this device anymore. :-(
convert -depth 8 -size 800x600 rgb:/dev/fb/0'[0]' \
-channel RGB -separate -swap 0,2 -combine \
outfile.png
You do need to know what the size of the display was, and the
retrieved image was in in blue, green and red order, so the
second line swaps the blue and red channels.
For a more controled read, the "stream" command -format should
be able to give you a highly controled conversion of raw data to image.
