[comp.windows.x] wasting time on a color vax

    I'm trying to display some color images on a VAX station running X10.
It is just something I'm doing weekends for 'fun', if that can be called
fun.  

    I have 24 bits of color info, which I know how to scrunch down to 8
bits.  Now I want to use all 256 colors I have available at one time.  I
don't care if I mess up the rest of the colors on my screen, just so long as
I can set them back afterwards.  

    Before I get 20 responses all saying "look at the X manual", or "have
you tried this command?", please take a look at the pertinent part of my
program, which I can mail you.  It seems that all the other colors on my
screen are "in use" and cannot be changed, leaving me with around 200 - 220
colors.  I've tried most of the color commands in the X manual in an attempt
to use all 256.  If someone out there already has a program that will read
color pictures and display them in 256 colors, that would be great.

    Another problem: I can only stick 128k of info in a Pixmap, so I break
my large pictures into pieces.  However, only the first Pixmap shows up
correctly.  The others contain garbage.

    Thank you,
