Package: exactimage Version: 0.8.5-4 Severity: normal Tags: patch Exactimage has different optimizations that allows to preserve the DCT or at least rearrange it without additional loss of precision during the operations. These optimizations depend on the major version of libjpeg. Result of an mismatch are crashes or other hiccups.
An example for such an hiccup is an endless loop. To reproduce on amd64 $ convert -size 100x100 xc:white white.jpg $ econvert -i white.jpg --rotate 90 -o test.jpg This can be resolved by replacing codecs/jpegint.h, codecs/transupp.c and codecs/transupp.h with the version from libjpeg8. A workaround is to build it against libjpeg62 --- System information. --- Architecture: amd64 Kernel: Linux 3.2.0-3-amd64 Debian Release: wheezy/sid 500 unstable www.deb-multimedia.org 500 unstable http.debian.net 500 testing http.debian.net 1 experimental www.deb-multimedia.org 1 experimental http.debian.net --- Package information. --- Depends (Version) | Installed ==============================-+-============== libc6 (>= 2.4) | libexpat1 (>= 2.0.1) | libfreetype6 (>= 2.2.1) | libgcc1 (>= 1:4.1.1) | libgif4 (>= 4.1.4) | libgomp1 (>= 4.2.1) | libilmbase6 (>= 1.0.1) | libjasper1 | libjpeg8 (>= 8c) | libopenexr6 (>= 1.6.1) | libpng12-0 (>= 1.2.13-4) | libstdc++6 (>= 4.6) | libtiff4 (>> 3.9.5-3~) | zlib1g (>= 1:1.1.4) | Recommends (Version) | Installed =========================-+-=========== edisplay | Package's Suggests field is empty.
