Photoshop CS4

More info

Since I was able to open a file simialr to the files I'm woking on with -alpha off switch.
I went back and check earlier versions of IM and noticed.

My coding skills are limited. But I recompiled with the following changes.
a) replace all 8BPB with 8BPS
b) changed psd_info.version == 1 to 2
resulting in if ((psd_info.version == 2) && ((psd_info.rows > 300000) ||(psd_info.columns > 300000)))

Saw one occurance of profile=GetImageProfile(image ...

Since PSB in 6601 was added I beleive some legacy PSD has been broken.

I tested with 6590Q8WINstatic and 6602Q8WINstatic WIN BINARY rel.
I created mpc and cache files then did conversions. Both versions 6590and 6602 generate same mpc and cache files.
then I converted mpc to both psd and psb.

for both psd and psb in CS doc looks like MAXPSDChannels should be set to 56.
