Public bug reported: When I convert some jpg image to tga format, the tga image is upside down.
The bug only appears with some jpg images, not all. I can convert thousands of jpg images without problems but in some rare images the bug occurs. You can find three jpg images that are known to fail there: https://dl.illwieckz.net/b/imagemagick/bugs/convert-jpg-to-tga-upside-down/convert-jpg-to-tga-upside-down-samples.zip I also attach to this bug report the smallest sample I have. If I convert from jpg to png, the png is ok If I convert from jpg to png then from png to tga, the tga is ok If I convert from jpg to tga, the tga is upside down You can reproduce by downloading the samples, then run this code in the directory containing the samples: for i in *.jpg do n="$(basename "${i}" '.jpg')" convert "${i}" "${n}.png" convert "${i}" "${n}.tga" done You can have a look of the result there: https://dl.illwieckz.net/b/imagemagick/bugs/convert-jpg-to-tga-upside-down/convert-jpg-to-tga-upside-down.png You can also download this script there: https://dl.illwieckz.net/b/imagemagick/bugs/convert-jpg-to-tga-upside-down/convert-jpg-to-tga-upside-down.sh ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: imagemagick-6.q16 8:6.9.10.14+dfsg-7ubuntu2.2 ProcVersionSignature: Ubuntu 5.0.0-21.22-generic 5.0.15 Uname: Linux 5.0.0-21-generic x86_64 ApportVersion: 2.20.10-0ubuntu27.1 Architecture: amd64 CurrentDesktop: GNOME Date: Sun Aug 4 01:59:00 2019 SourcePackage: imagemagick UpgradeStatus: No upgrade log present (probably fresh install) modified.conffile..etc.default.apport: [modified] mtime.conffile..etc.default.apport: 2018-06-16T17:39:00.798346 ** Affects: imagemagick (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug disco ** Attachment added: "noships.jpg" https://bugs.launchpad.net/bugs/1838860/+attachment/5280694/+files/noships.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838860 Title: convert translates upside down some picture when converting from jpg to tga To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/imagemagick/+bug/1838860/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
