[Octave-bug-tracker] [bug #44736] OpenGL / gl2ps printing alters or drops axis outline

[Dan Sebald]

Follow-up Comment #4, bug #44736 (project octave):

It may be a viewer issue, but I think only because the layout of objects is
such that it brings out the intricate rendering details of the viewer.

I import patch4.svg into Inkscape and then decompose the plot into atomic
elements.  The white background is drawn as two triangles rather than a
rectangle.  Not a surprise, I suppose, given the octagon and hexadecagon are
triangulated.  And there are, in fact, some other elements coinciding with the
right and top border--some sort of zero thickness fill that only shows up as
dashed outlines in Inkscape--something that I can grab and move around.  There
are two such phantom fills for both the top and right axis borders.  The left
and bottom borders have no such phantom fill.  I believe that is the source of
the problem.

I don't think there is anything that Octave can do.  gl2ps needs to lay things
out in a more render-friendly fashion.
