libpng-1.2.30 and/or gimp2-2.4.5 - Gimp fails to open certain PNG files

Reported by: ddbrierton (Darren Brierton) Owned by: macports-tickets@…
Priority: Normal Milestone:
Component: ports Version: 1.6.0
Keywords: gimp, png Cc:

Description

Gimp will not open certain PNG files (example attached) although they appear to be valid. The files were created in Photoshop, and can be opened by Preview and Safari. The files can also be opened and edited in Gimp 2.4.6 (gimp-2.4.6-1.fc8) running on Fedora Core 8.

Precise error message from Gimp:

PNG image Message

Error while reading '/Users/darren/Desktop/background_img.png'. File corrupted?

GIMP Message

Opening '/Users/darren/Desktop/background_img.png' failed:

PNG image plug-In could not open image

If I start Gimp from a terminal and then open the file this error message is printed to the terminal:

libpng error: x[DA][94][FD]: invalid chunk type

Running:

Mac OS X 10.5.4
MacPorts 1.6.0
gimp-app                       @2.4.0          aqua/gimp-app

I think this is a regression in libpng, as I can reproduce your error with 1.2.30, but it works fine with the newest version, 1.2.31. Try upgrading libpng and see if that works.

Yes, the upgrade to libpng 1.2.31 fixes the problem. Thank you!
