Hello,

You have thrown a lot of things out here - many of which I don't follow.

Could you post to the news group the following...

print, SIZE(image_name)
print, MIN(image_name)
print, MAX(image_name)
DEVICE, GET_DECOMPOSED = thisDecomp
print, thisDecomp

Also, what do you mean by "black and white images"? Do you really mean
greyscale or do you mean bilevel (like 0 and 1 or 0 and 255)?

Cheers,
Ben
