<Note> What is Error Diffusion?
It is a method to present the color image or black and white image with less number of
bits/pixel, which may produce few visible patterns such as a snake-like pattern for a certain
type of image but in general the capability of sharp representation is excellent.
Disadvantage is long processing type and this is because errors are measured and
amount of computing required for distribution the errors to neighbor pixels.
It is recommended to use the diffusion algorithm with this SDK.

[Discussion]
