A while back I tried to use the "object raster" script to create a stippling effect on a raster image. My biggest challenge was figuring out how to increase the dot density in dark spots. Object raster will produce bigger dots in dark areas and smaller dots in light areas but always a dot for each pixel. My solution, I ended up running the script on several rasters, each progressively lighter, and laying the results on top of one another so the dark spots ended up with larger and denser dots and the light spots ended up with smaller, less dense dots. (then using illustrators "transform each" to randomly move them from their original grid orientation).
can anyone think of a way to do this automatically? ideally with only one raster image and possibly with controls that would allow options like:
A. uniform dot size with varying dot density
B. varying dot size with uniform dot density (essentially object raster but with some randomization to keep it from looking like a halftone grid)
C. varying dot density with varying dot size (this would be the very similar to stippling. and with a way to control the amount of variation allowed would be fantastic)
i'm not a programmer, i'm just an artist but I think this would be very useful.
