Brian,

I'm glad my SAVEIMAGE procedure is serving you well. I'm not sure what you
were doing wrong: There are quite a few variables to take care of. For
example, if you are using TVRD to read from any 24-bit display, you should
have decomposed color turned on, e.g.

device, decomposed = 1

I used to worry about this problem and all the other myriad possibilities
for screw-ups in reading the display and writing an image file. But then I
wrote SAVEIMAGE, thereby putting the intelligence into software where it
belongs. A close reading of the code might be instructive (heaven knows I
have to go back and read it to remember what its doing!).

Cheers,
Liam.
