Description Hans Ecke 2011-03-08 17:33:14 UTC

Description of problem:

Liquid Rescale / Seam Carving is a technique for resizing images that preserves as much image content as possible, by preferably removing uniform areas. This technique is important for photo editing. It is a major boon for Linux that applications like the Gimp support it. ImageMagick should support it too, for command line / server-side / headless operation.

The algorithm is exposed inside the liblqr-1 package, with the development files inside the liblqr-1-devel package. If liblqr-1 and liblqr-1-devel are installed at the time that ImageMagick is built, a "-liquid-rescale" command line switch becomes available which functions as you would expect.

liblqr-1 and -devel have minimal dependencies: they only require glib2.

Please add liblqr-1-devel as a BuildRequire to ImageMagick so that our standard ImageMagick "convert" command can offer support for seam carving.

Er, on my system I get the standard delegate lib error when trying to use liquid rescale. Looking at the diff for the linked build[1], the changelog indicates that a BuildRequires was added but the diff doesn't actually contain the indicated BR. Neither does the current master.
