[magick-users] Convert photos for laser engraving?

[George Vandenberghe]

As someone who doesn't do much with images anymore you should take my
advice cautiously.   However the PBM file format is a simple way
to represent black/white images one bit per pixel.   The only way
to get grayscale with PBM is by varying the density of black and white 
points.
Look at the dithering options in convert for possible assistance.    However
dithering does point density manipulation and lines are  a problem I've not
worked with.
