Cannot read properly simple psd file with ImageMagick 6.9.1-7

[246246]

Input image is here: https://www.dropbox.com/s/swc28z9jtrcey ... o.psd?dl=0
It should show text "Hello!" on transparent background. The file can be read properly with Gimp 2.8.10 and Photoshop CS6.

Here shows the warnings from Windows command:

Code: Select all

There are no warning/error output with the same command above from IM 6.9.1-6 on Windows and 6.9.1-3 in Cygwin - using grep instead, both of which show properly the image with display command.

Best wishes,

Those are only warning messages. However, the image is corrupted when displayed in Imagemagick 6.9.1.7. It does open fine in PS (CS). If I save it from PS without any changes, then it displays fine in IM. Did you save with maximum compatibility?

Thank you for your reply. Oddly, It corrupts like the following:

6.9.1-6 result of display

6.9.1-7 result of display


As you said, when I resave it as another file with PS (with maximum compatibility option), it can be read fine also with 6.9.1-7, but still output the same warnings (that are not produced when using IM 6.9.1-6).

The warnings do not mean anything significant to the processing of the image. As long as they are warnings and not errors. I do not know what has been upgraded in I 6.9.1.7 from 6.9.1.6. The IM developers would have to comment. But PSD and TIFF have been improved to add new features in the last few releases. See the changelog at http://www.imagemagick.org/script/changelog.php, which seems to be missing the 6.9.1.7 changes.

At a glance, something has changed to in reading layers.

Removing call of DiscardBlobBytes() might cause this problem, but I have no debugging environment now. So it's just a guess.

I see nothing in the changelog now regarding changes to PSD files. But changes could have been made and not commented in the changelog or were a ramification of some other changes elsewhere. I think the IM developers will need to comment and check this out.

This is indeed a problem with the PSD reader and it will be resolved in 6.9.1-8. Its happening due to the change of 'if (length > 0)'. This has been fixed in the latest beta.
