Class TAdBellDithering

Unit

AdBitmapEffects

Declaration

type TAdBellDithering = class(TAdErrorDiffusionDithering)

Description

TAdBellDithering uses the an optimized FloydSteinberg convolution kernel for dithering the bitmap. TAdBellDithering gives you a little better results than TAdFloydSteinberg dithering but needs more time in calculating the results.

TAdErrorDiffusionDithering

TAdErrorDiffusionDithering represent a sort of dithering algorithms that use a convolution kernel in order to diffuse the quantization error to neighbour pixels.

TAdDitheringFilter

A dithering filter allows you to dithre a bitmap.
