support for writing GIFs
Last modified: 2011-12-16 23:37:47 UTC
Please describe the problem: When viewing a .gif file and trying to save it to a different location I get the following error message. File format is unknown or unsupported Eye of GNOME could not determine a supported writable file format based on the filename. Please try a different file extension like .png or .jpg. Steps to reproduce: 1. View a foo.gif file 2. Try to save as a different file bar.gif 3. Actual results: I get a popup window with the text File format is unknown or unsupported Eye of GNOME could not determine a supported writable file format based on the filename. Please try a different file extension like .png or .jpg. Expected results: That a new file bar.gif is written Does this happen every time? Yes, recently. Other information: Ubuntu Hardy
This is because the GIF plugin of gdk-pixbuf (which provides image loading/saving for eog) doesn't support writing GIFs. Reassigning.
I can confirm this behaviour on Ubuntu 11.04. I've tried with EOG and gThumb 2.13.1. The behaviour with EOG is as described above. The gThumb simply stalls at the save screen. Has this bug really been around for 3 years?
Not going to do this - gdk-pixbuf is not really a generic write-images-in-any-format library.
