Package: gimp-dds Version: 2.0.7-1 Severity: normal Open this file https://vrmlengine.svn.sourceforge.net/svnroot/vrmlengine/trunk/kambi_vrml_test_suite/textures/016marbre.jpg and save as DDS, checking "Generate mipmaps" (everything else default). Look at mipmaps in the resulting file (e.g. open saved file back by gimp-dds). The lowest 1x1 mipmap contains one almost black (color is #1d1c1c) pixel.
Which is wrong --- the base image is obviously mostly white, so the final 1x1 mipmap should be much lighter. Also, all the colors on previous 2x2 mipmap are much *lighter* than #1d1c1c. So something went wrong when generating (at least) this mipmap level. Not sure whether 2x2 level is 100% correct either (it's a little too dark anyway, although not as black). My resulting DDS file is on http://michalis.ii.uni.wroc.pl/~michalis/tmp/016marbre_with_mipmaps.dds I also tried selecting both mipmaps and DXT1 compression, result is here: http://michalis.ii.uni.wroc.pl/~michalis/tmp/016marbre_s3tc_with_mipmaps.dds Result with S3TC compression has the same problem, so this problem is not related to S3TC. Oh, and I tested reading these DDS files with my own programs, and yes, the last mipmap level *is* almost black. So it's not a problem in DDS reader --- trouble happens at DDS writing, when mipmaps are generated. Versions: I initially saw both problems with 2.0.7 (more precisely, 2.0.7-1 version of Debian package "gimp-dds"). I checked out and compiled trunk (from http://nifelheim.dyndns.org/svn/gimp-dds/trunk ) and both bugs are still there. (I don't see any changes in SVN since around the 2.0.7 release anyway.) My gimp version is 2.6.7-1.1. Submitted by email to upsteam author (mail at the bottom of http://nifelheim.dyndns.org/~cocidius/dds/), without an answer, so resubmitting to Debian hoping for a fix :) -- System Information: Debian Release: squeeze/sid APT prefers testing APT policy: (990, 'testing'), (500, 'stable') Architecture: i386 (i686) Kernel: Linux 2.6.26-2-686 (SMP w/2 CPU cores) Locale: LANG=pl_PL.UTF-8, LC_CTYPE=pl_PL.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages gimp-dds depends on: ii libc6 2.10.2-2 GNU C Library: Shared libraries ii libgimp2.0 2.6.7-1.1 Libraries for the GNU Image Manipu ii libglib2.0-0 2.22.3-1 The GLib library of C routines ii libgtk2.0-0 2.18.3-1 The GTK+ graphical user interface gimp-dds recommends no packages. gimp-dds suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
