I often use the 'trace bitmap' function in Inkscape to create a vector image from a raster image. However, on larger or more complicated bitmaps, the program completely freezes. GUIs being what they are, I know that a command-line based approach would suit the task. So what's a good way to do that?

  • Not an answer, but I can't imagine wanting to do such a visual task in a CLI...

    @e100 It's a matter of clicking a tab and choosing a brightness cutoff. I'm not talking about tracing it using a tablet.

  • OK - I haven't used Inkscape to be honest, but in other apps tracing generally involves tweaking several factors interactively.

The software that powers Inkscape's bitmap tracing function is actually a non-GUI program called Potrace, so you're in luck:

This one also supports centerline (for CAD) https://github.com/autotrace/autotrace
