I have posted this elsewhere, but it does not show up on your search, so here goes again. I have created and just patented a new way to upres image files. I need to able to apply it to large images, so I have to be able to write the data to a .psb. Adobe's 50 page description of the header is way less than helpful. I need to be able to construct the simplest possible header: no compression, no custom notes, one layer. Anybody care to instruct me?
