Version: (using KDE KDE 3.5.2) Installed from: Ubuntu Packages OS: Linux I have some strange JPEG picture that is rendered incorrectly in *all* KDE software - KolourPaint/Gwenview/Konqueror/.... (with exception of Krita which works 100% correct) - it makes me feel that there is some problem in KDE libs/base/core. The strange JPEG originate from a PDF file. (and, perhaps has CMYK colorspace) This bugs inverts Red & Blue channels. ============================================================================= GNOME software (GIMP 2.2) & ACDSee classic renders that JPEG almost correctly (small glitch/color mistake). Software that reads the files 100% correctly: (PDF or JPEG) 1) Adobe Acrobat 7 - PDF 2) MS Windows XP Paint (strange for MS :) - JPEG 3) KDE Krita 1.5.0 - JPEG Tested on: Windows XP SP2, Kubuntu 6.06 Dapper w/ KDE 3.5.2, SUSE Linux 10.0 w/ KDE 3.4.2 - bugs in KDE detected in both 3.4.2 and 3.5.2 versions.
Created attachment 16411 [details] The buggy JPEG that causes problems in KDE. I think it is a non-standard CMYK JPEG. (instead of RGB) NOTE: compressed into 7-zip - because it takes over 1MB and not works with KDE bugzilla otherwise. Use Ark to open it.
Created attachment 16412 [details] The original PDF file. Works correctly with Adobe Acrobat Reader 7.0. Almost correctly with the GIMP 2.2. w/ postscript plugin.
Alternativaley, the buggy JPEG image is available "as-is" (without 7-zip) to first few people that click below: http://www.yousendit.com/transfer.php?action=download&ufid=64DED58D16614923 NOTE: to correctly see it use: MS Paint XP Adobe Photoshop 9 CS2 KDE Krita 1.5.0
Problem confirmed to be occuring on debian sid with kde 3.5.5 too. Although if kde uses libjpeg I don't see how its a kde problem .. :)
Sorry, I meant kde 3.5.3, really now, I wish someone would give me a 3.5.5 pre release, but let me not change the topic here ;)
update: GNOME is affected too by similar bug - but not exactly the same. see: http://bugzilla.gnome.org/show_bug.cgi?id=343667 So it points us to libjpeg bug - but where is libjpeg bugzilla ? plz help !
http://www.ijg.org/ or maybe you contact the authors (should be in the source packages or documentation) If you're sure that it's a libjpeg problem, please close this report. Thanks.
I now made a small Qt only testprogram. I found this to be a Qt3 bug, as on the same machine the same app compiled with Qt4 and the same libjpg shows a correct result (altough it's interesting that KDE3 can show the correct image in the preview area of the "save as" dialog...)
Hello, In KDE SVN trunk r881398 i cannot reproduce this bug anymore. Thanks.
