[Octave-bug-tracker] [bug #47191] contourf with false colour when saving to pdf

[Pantxo Diribarne]

Follow-up Comment #3, bug #47191 (project octave):

Hi,

I can't reproduce either on linux but this may well be due to a bug in gl2ps
which could show differently in different opengl implementations: the current
version of octave on windows (and on linux) uses gl2ps 1.3.8 which was
affected by a bug that make some patches be hidden behind others. As I believe
that the latest mxe-builds for windows uses the latest version of gl2ps
(1.3.9), can the OP test octave 4.0.1 release candidate:

@Mike:
The diagonal line are a known bug: patches are tesselated into smaller
triangles and the lines you see are an artifact of anti-aliasing. I don't
think ghostscript is responsible, but rather that the viewer behaves
differently with eps and pdf files.
