Problematic pdf file
patch |
||
The file generates a /rangecheck error on --.discardtransparencygroup-- for me when using Windows. Both the HEAD and 8.70 revisions. -sDEVICE=ppmraw also gives the same result for me, so its not specific to PDF touput. Re-assigning to Alex as a PDF interpreter initially, this may need to go to Michael if it turns out to be a transparency problem. This problem appears first in
r10200 | mvrhel | 2009-10-20 23:50:46 -0400 (Tue, 20 Oct 2009) | 72 lines
Reintegration of gs_extendgraphic branch into trunk.
If .pushextendedgstate is commented out, the file runs to completion.
/q { ...
% PDFusingtransparency {.pushextendedgstate cvx} if
... } def
BTW, "PDFusingtransparency {.popextendedgstate cvx} if" should be,
probably, done only for a valid Q, i.e. after the checks.
And why "cvx" ? Removing this fixes the bug. Created attachment 6632 [details]
patch
Remove spurious "cvx" operators after .pushextendedgstate and
.popextendedgstate . Do .popextendedgstate after checking that "Q"
has a correspondingh "q". The latter is not necessary to fix this bug
but may help when PDF file has extra "Q"s .
The patch has been committed as a rev. 11615. Regression testing shows no differences. |
