rep_ordered_dithering

No arguments

Description:

level>0,0<=dither<=1,threshold_map_iter>0,map_pal={ 0 | 1 },_use_previous_threshold_map={ 0 | 1 } :

level_a>0:.:level_z>0,0<=dither<=1,threshold_map_iter>0,map_pal={ 0 | 1 },_use_previous_threshold_map={ 0 | 1 }  :
[palette],0<=dither<=1,threshold_map_iter>0,map_pal={ 0 | 1 },_use_previous_threshold_map={ 0 | 1 } :
level<0,0<=dither<=1,threshold_map_iter>0,spread,_use_previous_threshold_map={ 0 | 1 }
 
Apply ordered dithering effect onto image.
 
Note A: depth_a:.:depth_z implies that the first argument is a set of arguments joined by the : char. This is used for separating bit depth channels.
Note B: Negative value is used to alter values of images without indexing, and that is useful for generating windows-based ordered-dithering with the use of rep_index_by_window_and_color_restriction command.
