Large XMP:DocumentAncestors: convert/identify app crash

[krikke]

I'm trying to convert a rather large PSD file to jpg.

Not using any fancy attributes just

Code: Select all

convert.exe "psdsource" "jpgdestination"

The PSD file opens just fine in Adobe Photoshop but it crashes the "convert" & "identify" executable upon converting/identifying.
I started investigating the metadata using exiftool. It seems this PSD file contains a lot of data in the "XMP:DocumentAncestors" tag. (see warning exiftool)

Code: Select all

Warning : [Minor] Excessive number of items for photoshop:DocumentAncestors. Extracted only the first 1000.

ex. XMP:DocumentAncestors data:

Code: Select all

If I strip this metadata field from the PSD file the conversion succeeds else it crashes the convert.exe/identify.exe application.

Post a URL to an example PSD image. We need to download it and reproduce the problem before we can provide a fix.

[krikke]

I have sent you a PM with the download url.

Your sample image convert without complaint under Linux and ImageMagick 6.9.1-2, the latest release. We will try under Windows later today and report back.

I'm using windows v. ImageMagick-6.8.7-Q16

[magick]

Try ImageMagick 6.9.1. There is a mention of a large XMP problem in the ChangeLog since 6.8.7. Its likely the patch fixes the problem you are having.

[krikke]

I can confirm that the issue is fixed with ImageMagick-6.9.1-2 (portable win version)

Thanks for the quick response.
