Christian, You're wonderful - thanks for getting back so promptly and helpfully. I'm just downloading the latest boost version (am using 1.42 at the moment which doesn't seem to have the cymk16161688_image_t you refer to) and will try out your suggestion. And this is almost certainly an RTFM question but how does one know which input image type to use? If you had a moment to point me in the right direction or to jot down an elegant code snippet to get me on the right track for reading different flavours of TIFF files I'd be eternally grateful ... Meanwhile I'll go RTFM ;) Thanks a million for taking the time to help. All the best, ... Corinna
Corinna, this has to wait until tomorrow. Hope that's ok with you.
But I can see from the source code that the input image should be cymk16161688_image_t and not just cymk8_image_t.
