Geert,

My raster-to-toolpath uses the "image magic" libraries to handle reading
and writing the image files. It will take as input any type of image file
that image magick can read. I've used JPG, but usually have converted
files to PNGs before passing them to the converter software.

To make G-code, though, I'll need some simple tutorial. The format of the
tool path files I generate is simple, but not G-code.

For example, to move to a position:

M xx.xx yy.yy zz.zz PP.PP RR.RR WW.WW
where the x,y,z,P,R,W values are the x, y, and z cartesian axis positions,
and the Pitch, Roll, and yaW angles.

To cut to a position, replace the M with a C. The only difference between
M and C is that there are two commands to set movement speed, and the speed
for C moves can be different (usually slower) than the speed for M moves.

The current raster-to-toolpath code generates code where the P, R, and W
values are all zero.

The description of the complete move language is at:

I'd be happy to add a G-code output writer, if someone would give me a
pointer to what G-code works for typical CNC setups.

I've gotten some requests for the code. I can provide direct CVS access,
or could see about preparing a tar file for download.
