[Octave-bug-tracker] [bug #45494] Patches have spurious (antialising) lines in vector printout

[John W. Eaton]

Follow-up Comment #11, bug #45494 (project octave):

I started looking at this problem today, then found this (and the other) bug
report.  Before I read through the comments, I discovered that the eps file
generated by gl2ps does not appear to have the extra lines, but the generated
pdf file does.  Or at least the artifacts do not appear when I view the
generated eps file with evince.

Looking at what Octave's print command is doing, I captured the EPS output
from gl2ps and the ghostscript filter command, which is essentially this:


gs -dQUIET -dNOPAUSE -dBATCH -dSAFER -dAutoRotatePages=/None -sDEVICE=pdfwrite
-dLanguageLevel=3 -dEmbedAllFonts=true -dOptimize=true -dEPSCrop
-sPAPERSIZE=letter -dFIXEDMEDIA -sOutputFile="output.pdf" gl2ps-output.eps


The input and output files are attached.

Since displaying the PostScript file doesn't show the artifacts, is there some
way to generate a PDF file that will behave the same way?
