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
