Thank you for answering,
but you're right, this is quite a big histogram. I tried the idea, but it
took almost 1 minute to display this beast (on a Sun Ultra 5).
That doesn't fit to my needs.
I want to take a sequence of pictures from a CCD as rawdata. I have to
inspect the images before storing them to my file. That's the reason why I
want to avoid downsampling and the time for waiting for the pictures adds
up...
Any othert idea?
Greetings
Markus
