[Magick-bugs] PSD clip path information missing in newer versions

[Coleman Nitroy]

Hello all,

This is a bit of a cross-post from the magick-users mailing list but I  
figured it was more of a bug and I have since gotten some more  
information on the issue.

I have been having issues with clipping paths using ImageMagick 6.3.x.  
The specific issue is the clipping path seems to be ignored on PSDs.  
6.2.x up to 6.2.6 seems to work fine with the clipping path and I  
would use this as a solution but, only on PSDs made with CS2 and below  
work. Here are the steps I take to attempt to clip an image:

* I created these two test files both with clipping paths

PSD version: http://cole.nitroy.com/Files/Temp/Test.psd
TIF version: http://cole.nitroy.com/Files/Temp/Test.tiff

* To test the PSD I run:

$ convert Test.psd -fill white -draw "color 0 0 reset" -clip -draw  
"Image Copy 0,0 0,0 test.tiff" Output.tiff
convert: no clip path defined `Test.psd': Bad file descriptor.

* This creates Output.tiff but no part of the image has been clipped  
so this is obviously a failed method.
* I will then try testing the tiff version instead with the command:

$ convert Test.tiff -fill white -draw "color 0 0 reset" -clip -draw  
"Image Copy 0,0 0,0 test.tiff" Output.tiff

* This works showing that clipping does work, but not with PSDs.

I then try to convert the PSD into a tiff and see if the clipping path  
is maintained.

$ convert -profile ColorArt85290.icc Test.psd -profile sRGB.icc - 
colorspace rgb  Test.tiff

* This outputs a tiff with no clipping information in it making it  
useless to me.

I shall note that all of these commands work in 6.2 (with the  
exception of with PSDs created with CS3) and properly maintain the  
clipping path and clip it properly.

I can provide any data, more files, or the debug output for these  
commands. I ran a diff on 6.2.6 (which works) against 6.3.8 on coders/ 
psd.c and poured over it for a bit but nothing stood out as the  
culprit. I did notice that in the ChangeLog for 2006-04-10 6.2.7-0, it  
states: Read PSD pre-combined layer. Maybe this change caused  
unintended consequences that have gone unnoticed?

Thanks in advance,

Coleman Nitroy
