[comp.sys.mac.programmer] Problems with colors on IIci

meynard@IRO.UMontreal.CA (Meynard Yves) (12/04/90)

Sorry if this question has been seen before, I haven't used rn in over a year!

We are experiencing problems with a program developed here at Montreal
University when running on a MacIIci. The program loads its set of colors in
the form of a 'pltt' resource; on all machines so far this has been problem-
free. But on a borrowed IIci, with a 2-page display and 4 gray scales
(admittedly a non-recommendable setup for a color chemistry program, but this
is no excuse), all colors show up as black, even the entry for white! I know 
the machine is fine, since our about box, which contains colors, appears in 4 
shades of gray thru the good graces of the Dialog Manager.
Is 32-bit Quickdraw causing the trouble? Do I need a different 'pltt'?
Is there special documentation for 32-bit Quickdraw which we do not know of?
If so, where could this documentation be found? Any help or wisdom on the
subject would be greatly appreciated. If the answer is old news, please answer
thru e-mail to spare the net, otherwise feel free to post...
