I read a psd file format specification document which is downloaded from internet. As far as I can see, the last part of the file is image data section, which is precombined image. >From the document
Photoshop CS File Formats Specification<http://libpsd.graphest.com/files/Photoshop%20File%20Formats.pdf> page 47 it saids that The image data. Planar order = RRR GGG BBB, etc. The problem is when I try one of my psd file with 16 bit, rgb mode with alpha, the order of saved channel is RGBA And 8 bit mode, the order is ARGB. I could not find any clue why it works this way, wonder is there any place in the psd file decide the order of these channels. Or is there any official psd format specification from adobe, I could not find it. Thank you in advance.
