[magick-users] Convert photos for laser engraving?

[Kent]

Hi folks --

I have a client who wants software to convert photo images into a 
form that can be laser-engraved into metal or wood.  I suppose this 
will involve edge detection, and/or a way to translate the gray scale 
into patterns of lines that give the impression of varying 
shades.  The client has specified that the resulting files must be 1 
bit per pixel.  Can IM & MagickWand do this?  Does anyone have 
recommendations on what sort of operations to use?

Thanks --
