With the free open source Inkscape vector graphics application you. it goes bust with open paths and when the curve is near itself. A vector image allows you to edit and resize the image much more easily than a bitmap.
there's no easy to input numeric offset value, it must be adjusted by eye.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. But unfortunately, neither can automatically trace images and convert them to vector format directly on the iPad. If your original was a closed shape like a circle, no divisions at nodes are needed, only Break apart. Go to windows and then Click Image Trace. Do inkscape work, raster to vector, redraw, svg, pdf, eps. Remember to confirm all divisions with Path > Break apart. Convert to vector tracing, raster to vectorize images, turn logo into vector art. Traced bitmap, fill removed, 0.5mm strokeĭivided with the node tool to 2 separate curves, end segments are deleted. Stroke is outlined (Path > Stroke to Path), removed the fill, new stroke width 0.5 mm Divided again like in step 3. 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) In Inkscape the edge will be 2,5mm aside from the path > one of the edges shoud be the wanted centerline trace. SVG by default but there is an option to save as. I guess you want so called centerline tracing or a way to convert normal Inkscape tracing result to it. To save your vector, go to File > Save As and select your extension.
