Hello ... Sorry about the multiple posts of my last response... (my fault)...

Yes colour planes.... 1 for grayscale, 3 for RGB and 4 for CMYK

I'll email you the full spec but I'm not sure whether it tell you anything new....

I've done some basic testing and what you've done so far is already extremely useful....


I spoke with a colleague who was parsing the tags using some VBscript and he
said that he often saw some extra bytes at the end of the tag which he could never explain.
They were not always there....
