[Pkg-gmagick-im-team] Bug#844594: imagemagick: Artefacts running -sharpen on CMYK images

Thu Nov 17 13:22:57 UTC 2016

Package: imagemagick
Version: 8:6.9.6.2+dfsg-2
Severity: normal

Hi,
Calling "convert -sharpen" on a CMYK image results in artefacts and distortions
(such as black lines across the image or black parts missing entirely).

Examples are linked at the upstream bug:
https://github.com/ImageMagick/ImageMagick/issues/299

This has been fixed in 6.9.6.5 or alternatively via
https://github.com/ImageMagick/ImageMagick/commit/b1b4057233710e30d7d68bf8d8a5fcbd0eb7b275

Cheers,
        Moritz
