1997.02.13 23:37 "LZW & more than 5 image channels.", by Gabe Foster

Hello,

I seem to be exercising some rarely used features of the tiff library. Has anyone tried writing more than 4 channels to a file with lzw compression? When I try this with a 720x486 image that is just a grayscale ramp, I get a strangly cropped image. It writes with no error, and reads with no error, but the right hand third (about) of the image is black, the rest is ok.

Any Ideas?

--> Gabe
