[Gimp-print-devel] dither stuff

[Robert L K. <rl...@al...>]

I've been playing around with an ordered dither matrix, mostly for my
own edification, and it's producing interesting results, when my
printer cooperates (the lack of cooperation has nothing to do with the
dither pattern; it's a cartridge refill that I did this afternoon that
it seems unhappy about).  It produces somewhat interesting effects;
the dither pattern is very fine, but it produces fine diagonal lines
(not the error diffusion kind; it produces diagonals because I've
biased the matrix position to avoid horizontal and vertical lines).

A side effect is that the output files are much smaller than with
error diffusion.

I haven't put anything into the GUI for it.  Right now it's hardwired
into the Epson driver in my sandbox.  I could check it in if people
want to play with it.
