[Inkscape-user] Tesselation lines in svg

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
