Very easy for this but probably not for what you want to do, because it's a vector format. The photoplotter projects an image of a selected aperture onto light-sensitive film. You can either flash the light on and off again to create a pad, or draw lines by moving with the light on. But it does not lend itself at all well to rasterised images!

There will be a disc image to play with once I have put together a few more component footprints (and maybe an improved tool for creating them).
