![]() The Trace Bitmap and Bucket Fill tools are described in parts 79-81, but I recommend starting from part 76 where I also show some manual tracing techniques. Select all Nodes (Ctrl+A) and click 'smooth lines' at the top Manually move some nodes, bezier handles to correct small errors. Simplify the model (Path -> Simplify or Ctrl+L) a few times. This is a subject I cover in some detail in my tutorial series in Full Circle Magazine (free download) - though it predates the addition of centerline tracing, and the layout of the Trace Bitmap dialog has changed somewhat in 1.0. Use the Bezier tool to closely trace the bitmap with straight lines. Generally the bucket tool is not a good choice - it should usually be one of the last things in your arsenal - but for filling a traced bitmap the only other practical alternative is manually drawing the shapes in a layer below the traced bitmap. ![]() Try increasing the Grow/shrink parameter, but this tool always struggles with sharp corners. ![]() Turning off the stroke and setting a fill might be all you need to do, depending on your use for the traced shape.Īs to the white border around the filled colour - that's nothing to do with the bitmap tracing process, and everything to do with the bucket fill tool. Going back to the thin rectangle above, you can see how this would result in a shape that has two lines close together. The problem with double lines is probably that your path has a stroke but no fill. Now mentally make that rectangle thinner and thinner, until it's the thickness of a pen or pencil stroke - it still gets traced as a filled path. During processing the GUI will indeed be locked, Windows might report Inkscape as 'nor responding' if you try to interact with it during this time. Consider tracing a filled rectangle - you would expect to get a filled path as a result. Even though your image may, to you, seem to be made up of individual lines, to the tracing code they're thick shapes to be traced around. In anything other than centerline tracing mode, Bitmap tracing will produce a closed path.
