One can ask "why all this complexity, why do you not simply use Path > Dynamic offset?" Tested, how well the result fits in the original traced curveĬonclusion: quite as good as the original tracing Stroke is outlined (Path > Stroke to Path), removed the fill, new stroke width = 0.5 mmĭivided again like in step 3. In Inkscape the edge will be 2,5mm aside from the path => one of the edges shoud be the wanted centerline trace. New colors are selected to make this explanation clearerĭeleted the red curve, the blue curve got 5 mm wide stroke. If your original was a closed shape like a circle, no divisions at nodes are needed, only Break apart. Remember to confirm all divisions with Path > Break apart.
Traced bitmap, fill removed, 0.5mm strokeĭivided with the node tool to 2 separate curves, end segments are deleted. If your curve happens to be uniformly wide and do not cross itself, you can get a good result:Ī bitmap curve, about 5 mm wide, high contrast, high resolution, sharp, no JPG compression artifacts (=easily traceable) I guess you want so called centerline tracing or a way to convert normal Inkscape tracing result to it.
