Bug Description

Binary package hint: ghostscript

If gv is invoked on certain PDF files, a ghostscript crash occurs. However if pdf2ps is run on the offending PDF, the resulting postscript file -can- be displayed by gv.

Attached is an example PDF which works with acroread. When fed to gv, the following appears in a pink "Ghostscript messages" window:

To work around the problem turn off "Antialias" in the "State" menu and the file will display immediately. To let gv permanently start with anti-aliasing turned off, choose "gv Options" in the "State" menu, turn off "Antialias" there, "Save" and "Dismiss".

You are hitting a general problem of recent Ghostscript versions. The anti-aliased X output (output device "x11alpha") is broken and most files do not display in this mode. The workaround for now is to use the non-anti-aliased "x11" standard output device. Therefore I have already changed the defaults in Ghostscript so that a simple "gs <file>" call uses "x11" and not "x11alpha".

I have added a task for "gv" for applying the workaround to the "gv" package so that it comes with anti-aliasing turned off by default.

The problem of the non-working "x11alpha" device is already reported upstream and I hope it will be fixed soon.

summary:	- Some PDFs crash with: /rangecheck in --.discardtransparencygroup + Anti-aliased X display mode of Ghostscript does not work, in gv anti- + aliasing needs to get turned off therefore

According to some ghostscript upstream bug (I do not remember which bug it has been) reducing the value of "-dMaxBitmap" to some very small value is a good workaround, even better than disabling antialias.

This can be done in the window "State -> Ghostscript options".

Feedback to the quality of this workaround is welcome.

According to http://bugs.ghostscript.com/show_bug.cgi?id=689734 this bug has been fixed in rev 12380 of ghostscript, and indeed, using Ghostscript 9.02 + patch 12380, the example file of this bug report is working as expected. (In case you may ask how to install that ghostscript: I did not do my tests with Ubuntu.)

BTW: To disable antialias by default, the following patch will do - just in case you still decide to apply it (patching ghostscript seems to be more reasonable now that a patch is available):

diff --git a/gv/src/gv_user_res.dat b/gv/src/gv_user_res.dat
index 3d8de9c..9ea1473 100644

GV.swapLandscape: False
GV.autoCenter: True

I will not change the ntialias default in upstream GNU gv, as a bugfixed ghostscript is available.
