first regard the PSD format.. precomp v0.37 doesnot work with it.. but here is a PSD parser.. http://www.telegraphics.com.au/sw/#psdparse .. the author wrote in his readme "* Normally, RGB images (and grey scale+alpha images) are written as composite
PNG with channels combined in one file"
so i used this program and it extracted the embedded png (which precomp does not recognize) i tested with stuffit v12 the result was...wooooow.. (2,232,900 bytes) while rar is (3,453,894 bytes) and 7z (3,441,798 bytes)
then i used advdef -z0 (to remove compression).. then rar 3,315,840 bytes and 7zip 3,072,274 bytes so still far away from stuffit v12 engine.. but ifi want to make an EXE from the stuffit file.. the result 3,565,817 bytes with exe stub of 140,907 bytes so the EXE stub does not support the complete sitx format features so the main program convert it into plain sitx with now (recomp) features..
here is the images http://rapidshare.com/files/116312661/Coat2.rar.html
its 24bit+8bit alpha.. so i hope the complete png format is identified in precomp v0.38
