Debugging and Profiling


When an empty file named DEBUG exists, Ink/Stitch will try to connect to PyDev (if it can’t, it will continue on without debugging). Also it will generate SVG files for debugging.


Create an empty file named PROFILE in your inkstitch directory. Ink/Stitch will then run under a profiler and dump the result to profile_stats. It will tell you what functions take how long to run.

Install snakeviz with pip install snakeviz.

Open the statistics with snakeviz This will display a really useful interactive graph in your browser.
