Potrace Plugin for Sketch

How it works

Potrace for Sketch is based on Potrace, a bitmap tracing algorithm developed by Peter Selinger.

• Select one or more bitmap images and run the plugin.
• Potrace places a new vector graphic on top of each bitmap, and hides the orginal.
• Potrace only processes bitmaps. If you want to process a layer with an image fill, use Layer > Flatten Selection to Bitmap first.

Example
