mindthegap is an opensource tracing software developed as a part of a project in Google Summer of Code 2014. It vectorizes bitmaps (currenlty supports png only) without introducing gaps or overlaps between adjacent areas.

- For Linux:
make -f makefile. The binary will be generated inbindirectory. - For windows: Directly use exe file in
exedirectory.
Use mindthegap -h, for further help.
If the input image is such that different regions of the image can have multiple shades of same color then use the noisy switch by -z.
