I am creating a set of thumbnails using convert -thumbnail. (on opensuse 12.2 and Version: ImageMagick 6.7.6-9 2013-03-18 Q16). The output of the program is a correct thumbnail but one of the Thumb property fields seems not to follow the Freedesktop standard properly:
Thumb::Image::height: 720
Thumb::Image::Width: 1280
According to http://specifications.freedesktop.org/t ... l#ADDINFOS, this should be with a capital H in height. This becomes an issue when reusing the thumbnail in, for example, Gwenview, which considers that the size information is missing on the thumbnail and just recreates it.
Bug in Thumb::Image::Height
Re: Bug in Thumb::Image::Height
We can reproduce the problem you posted and have a patch in ImageMagick 6.8.6-4 Beta available by sometime tomorrow. Thanks.
