Kurz: Anzeiger für PBM/PGM/PPM-Bilder auf der Graffiti-Videokarte
Long:
Shows PBM/PGM/PPM-files on the Graffiti video card. To move
outsized pictures use mouse, to change screen resolution
press F1, F2 and F3.
You may change the brightness of the picture using + and -.
Quit with mouse buttons, ESCAPE, RETURN or ENTER.
If you don't specify a screen resolution the program opens a
(hopefully) fitting screen. This procedure is then repeated
for every file.
Note: PPM-files will be reduced to 256 colors. Only in this
case the +o, +t, -c, -n, -o, -l, -e and -f options are available.
