I'm looking for references (to code and/or algorithms) for producing bit-map
color output using a half-tone screen algorithm. Since printers use half tone
screens to get lots of colors out of 4-color presses, it seems the same
technique would work well when trying to get 4-color (3 + black) computer
printers to do the same thing.
Algorithms for both variable width line and filled-area output would be useful.
I'd like to play with changing the angle of the screens (rotating them
separately in the X-Y and/or Z planes). Presumably, the screen is a true
filter, so that the final output is clipped at full resolution to the original
dimensions of the object being output.
I can (and probably will end up doing...) spend a lot of time to figure out
how to do all this, but if anybody has already done it, it would sure save a
lot of time! Are there any references to algorithms like this? Can anybody
think of anything else to add to it?
