PSD file compression and profile tagging

Hello,

we'd like to have an extension in psd.c source that imagemagick is able to write compressed .psd files.

For this it should be possible to optionally set compression through command line options.

The reason why we are looking for this feature is because .psd files written from imagemagick are approximately 4 times larger than those written from adobe photoshop!

A test file "test_magick.psd" has 14.4 mb when written from imagemagick and 2,8 mb when written from photoshop.

The file "test_magick.psd" has been created using "convert test.jpg test_magick.psd" command.

Additionally we have to use exiftool to tag a profile "ISOcoated_v2_eci.psd" to the converted .psd file. (would even be better if we could do this using imagemagick instead - please let us know how to do that)

Does anybody know how to do this (compression and profile tagging)?

ImageMagick produces uncompressed PSD images. We have writing compressed PSD images on our development schedule but do not currently have an ETA for when it will be completed.

Can we accelerate development of that feature in any way (donation or something else)?
