(*** This bug was imported into bugs.kde.org ***) Package: kghostview Version: KDE 2.9.1 CVS/CVSup/Snapshot Severity: normal Installed from: Compiled sources Compiler: Not Specified OS: Linux OS/Compiler notes: Not Specified I have a ps file with images in it. With anti-alias on and the default gs parameters at various zoom level various parts of the image are not displayed. This happens with gs 6.51 when it's called with -sDEVICE=x11 AND -dMaxBitmap=10000000. Solution: default either to -DEVICE=x11alpha (as (my) gv does) or remove the -dMaxBitmap=10000000 in the default. If you wanna take a peak at the file please mail me. (Submitted via bugs.kde.org)
further testing showed that it is easy to for example print preview a file in kword with the same result as in #33395 (some parts are missing). Same 'bug' same fix.

First of all thanks for the analysis of the bug. It's is a pity that this= =20 happens since the x11 driver usually gives better results than the x11alph= a=20 driver. Maybe I can adjust MaxBitmap a bit although making at too small=20 slows down Ghostscript considerably. Could you send me the file so I can s= ee=20 if newer ghostscript versions also have this problem. Greetings Wilco
http://partner.advantech.com.tw/epartner/Files/Temp/PCM-5820_DS-19.pdf With this file also some images are not displayed (using KDE 3.1 using gs 6.52 on Linux RedHat 7.2 with Qt 3.1.1) when changing the zoom factor. Some times you see the images, some times not, and sometimes kghostview crashes when zooming.
This is really a bug in gs 6.5x. I don't remember the details of all of this, but it has been fixed in gs 7.05. I myself have PDF documents which were unviewable before upgrading gs. Considering the still large marketshare of gs 6.5x maybe kghostview should cater for it, so I will leave the bug open, but marked down in severity.

Created attachment 1312 [details] test case This file shows works in gs 7.05 always and fails with gs 6.5x for certain values of MaxBitmap. This comes from bug 37287.
Subject: kdegraphics/kghostview CVS commit by luis_pedro: gs 6.5x doesn't work with -dMaxBitmap=... so we detect it and remove that option if we have a broken gs. Note that this might make postscript rendering slower or take an awful lot of memory, but it is better no optimization than one which breaks on certain files.
