Follow-up Comment #15, bug #45494 (project octave): @jwe: actually I do see antialising lines in the eps from comment #12 when I use either evince or Okular so xpdf/poppler version or graphics hardware may also play a role. The best result I have seen for eps files and 3D surfaces were obtained when I tried to remove the "GL2PS_NO_PS3_SHADING" option in gl2ps-print.cc. The drawback is that ghostscript is unable to convert those postscript level 3 files so we are back at the beginning. @Dmitri:As for the reason for not using the native gl2ps pdf output, I think the idea was to avoid having to fight format specific bugs. Actually the native pdf output is often nicer (it is easy to test it using the -dpdflatex devices) but it has bugs that the postscript doesn't have (and vice versa), see e.g. lit surfaces: clf (); peaks (); shading interp light cd /tmp print -dpdfwrite converted.pdf print -dpdflatexstandalone native system ("pdflatex native") open native.pdf open converted.pdf Note that if you remove the light in this example then "native.pdf" is much nicer than "converted.pdf". _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?45494> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
