Hi,
I use Octave [1] to generate plots as svg files and rework them later in Inkscape (0.48.4 in linux mint 17). As Octave uses opengl as its primary graphics renderer, polygons are always tessellated into smaller triangles. Unfortunately the boundary between triangles is visible on screen in Inkscape (see the attached simple plot).
This is also true if I simply draw 2 triangles that have a common boundary, i.e. using "snap to grid" to ensure edges have the exact same coordinates: I can see a white boundary line on screen (and in pdf/eps outputs) between the two triangles. Is there a workaround in Inkscape? Does svg specification have a flag that tels the viewer something like "don't draw boundaries"?
Thanks,
Pantxo
This is a known issue, related to Inkscape's anti-aliasing (which creates those crisp, clean lines), which I thought was going to be improved somewhat with 0.91. And when I look at your file, it does seem somewhat improved to me.
Here's some info in FAQ #C.7. -- https://inkscape.org/en/learn/faq/#There%27s_a_seam,_or_artifact,_between_ad...
I hope that helps :-) brynn

Hi,
Thanks, I'll have to test this very new Inkscape 0.91.
@Jabiertxo: the coordinates are not integers but they are identical.
