PSD conversion error in 6.8.0.4

[michaelmwu]

Using ImageMagick 6.8.0-4 on Ubuntu Linux x86 12.04, several PSDs are not converted correctly compared to 6.7.8-8

Compiled both using ./configure --disable-static --disable-installed --without-perl --without-magick-plus-plus --enable-shared --with-modules

Files are located here for now:

The command I am using is convert FILE[0] PNG_FILE

For the google apps files, the background stays white in 6.8.0.4, while onee of them is actually transparent

For pixelapse-avatar.psd, 6.8 generates this:

Your problems are two fold.

1) IM does not recognize background transparency in PSD images, only alpha channel transparency.

2) For your large dark image, IM changed from using non-linear gray to linear gray at IM 6.8.0.3

This works fine to fix it.

convert pixelapse-avatar.psd[0] -set colorspace RGB pixelapse-avatar.png

Perhaps a workaround for the first problem. Try converting to tiff first. This seems to work for me on IM 6.8.0.4 Q16 Mac OSX Snow Leopard
