Method Image.Colortable()->reduce()
- Method
reduce
object reduce(int colors)
object reduce_fs(int colors)
- Description
-
reduces the number of colors
All needed (see create ) colors are kept.
reduce_fs creates and keeps
the outmost corners of the color space, to
improve floyd-steinberg dithering result.
(It doesn't work very well, though.)
- Parameter colors
-
target number of colors
- Returns
-
the new Colortable object
- Note
-
this algorithm assumes all colors are different to
begin with (!)
reduce_fs keeps the "corners" as
"needed colors".
