The bug is reproduced in the current master branch on GNU/Linux and Android platforms. Hi, We also encountered this issue. Some things we noticed: 1) The issue starts when the output image area exceeds about 20.8Mpix (tested with different files increasing output resolution step by step, and it looks that it always starts at exactly the same point) 2) Everything is fine in 9.52, the problem started in later versions (9.53.x, 9.54, 9.55 all seem to have it) I tested with head (as of https://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=0f03d72f51f09eae5f3a5cfc452d58c19db2756c) and it seems to render fine. I just compiled the latest master and it does appear to be fixed, even for 10x higher resolution. Is there a test for this to make sure it doesn't regress again? |
