Welcome to the Drawbot_image_to_gcode wiki!

This software converts a JPEG to GCode line segments for use on a drawbot, polargraph, or vplotter.

It is written in https://processing.org so its simple to change and tweak. The basic algorithm is as follows:

1. Find the darkest pixel in the entire image
2. Lift up the pen
3. Move there
4. Lower the pen
5. Lighten the pixel a bit so it not the darkest anymore
6. Find the darkest pixel a couple pixels away from here
7. Draw a line to it
8. Lighten the pixel a bit so it not the darkest anymore
9. Repeat steps 6-8 about 1000 times
10. Repeat steps 1-9 about 200 times
11. Lift up the pen, and done
