I'm not sure if this is the correct forum, but here goes.

I have created a drawing in CAD for an absolute encoder. I can output in DXF file format. I want to have this engraved on glass The person who has the laser engraver says he can only take BMP or JPEG file formats.

Question what is the best way to convert DXF to Bitmap? I only want to do this one application so buying an expensive software program is not an option.
Thanks in advance for your help.
