Hi all,

Did someone already know about 16 bits/channel multilayer psd file parsing is different to that of 8 bits/channel multilayer psd file?

as far as I try, it seems 8 bits/channel model, image data is saved in RLE model, but it is quite different in 16 bits/channel,
we could easily find out once we load those two file into memory (with same context, only model changed).

Anyone who know which algorithm may 16 bits/channel multilayer psd taken for saving the layer image data?

Many Thanks!

Jerry Yu

yes, 16 bit/channel can be ZIP/FLATE compressed. (RLE doesn’t work well for anything beyond 8 bit/channel)

You can find the details in the Photoshop SDK (you’ll have to ask specifically for the PSD documentation).

Thank you very much Chris,

but I am wondering where can I get the specifically PSD documentation you mentioned? asking Adobe SDK group?

Would you give me some more help?

You have to request that after you get the basic SDK.
