I’ve been working on this an hour, all I get for g4 is mac … some tiff and jpeg stuff but this is gonna be slogging unless I can get some trick pointers. Okay,
An image consists of ( ? ) a bitstream which I may consider for the moment to be alpha rgb packed according to some spec. Would rather user cmyk but that will come soon enough.
Graphics will have headers that tell one such things as 640×480 and 1028×764 such as how the bitops packed the pixels. jpeg has advanced compression algora that are beyond me. I want { x , y } ordered pair has enough information that I can decide if that pixel is recordable as set, vis-a-vis “blank”
A great deal will be simplified if I can get past the information that assumes one does not wish to study bits, bytes, and Alpha + Color channel…gonna be needless waste otherwise.
