There are bugs when I open the ps file used . Please view appendix.
I'm attention. Best regards
Created attachment 2711 [details] foo.tar.bz2 This is a local copy of the sample files repackaged using a well-known free software tools. I cannot reproduce the reported effect on the display device at 300 dpi or lower resolution using v. 8.54 or current HEAD. Please provide detailed information about yoor platform, command line parameters, and compile-time options, if any.
Created attachment 2722 [details] screenshot of gsview showing the same effect as reported The region of interests is a small icon on the top right corner. It does require quite high magnification (beyond 300?). Reproduced with 32-bit gs and 32-bit gsview on x86_64 fc6.
minor change to summary to better reflect the nature of the problem.
Hin Tak: Please send the command line you use from gs (NOT gsview) and the reslution you have on your display. It would be best if it can be reproduced with a png16m or something. I assume that you will test with HEAD if it fails with 8.54 Thank you
Waiting for input from Hin-Tak
Created attachment 4314 [details] trimmed test file trimmed test file from attachment 2711 [details]
Created attachment 4315 [details] screenshot 1 at -r130 with x11alpha device screenshot of gs -sDEVICE=x11alpha -r130 "trimmed test file"
Created attachment 4316 [details] screenshot 2 at -r140 with x11alpha device gs -sDEVICE=x11alpha -r140 "trimmed test file" The visual artefact seems to be transparency related (DEVICE=x11 is clean). Both of these screenshots are with gs 8.62 on linux x86_64. svn current (9017) doesn't build. $ make make: *** No rule to make target `obj/@SYNC@.dev', needed by `obj/clist.dev'. Stop. Apologies, it has been a long time...
Working out it is transparency-related is useful - this: gs -sDEVICE=pngalpha -sOutputFile=test.png -r140 -dBATCH -dNOPAUSE \ "trimmed test file" gives a png file with a similar rendering artefact as with the x11alpha device.
Hin-Tak #9: The @SYNC@ means an autoconf substitution didn't happen. Did you re-run ./autogen.sh? If it still fails after that, please open a new bug at attach your config.log.
Sorry about the stale autoconf. svn9017 builds and has same issue as 8.62 with the pngalpha device as in comment #10. Somebody else can take the "AssignedTo" back now :-).
Re-assigning bugs which still have work to do.
Verified this has some strange rendering going on. Have you look at this Alex?
Bug still reproducible in Ghostscript 9.03
This bug is fixed in the current development version.
Please disregard my previous comment. The bug is still reproducible on x11alpha device.
Closing this as I verified that Adobe does the same thing, so it is not a bug but an issue with the file. To verify, 1) Distill with Acrobat. 2) Open the distilled PDF with Acrobat and in preferences set smooth line art. You will see the same rendering as occurs with GS.
