ShrinkARGBFormat Method
ShrinkARGBFormat(int, DitheringMethod)
Changes pixel format from 8 bits per channel to lower values with two-dimensional error diffusion.
Declaration
public void ShrinkARGBFormat(int bitsPerChannel, DitheringMethod ditheringMethod)Public Sub ShrinkARGBFormat(bitsPerChannel As Integer, ditheringMethod As DitheringMethod)Parameters
| Type | Name | Description |
|---|---|---|
| int | bitsPerChannel | The target number of bits per channel (from 1 to 8). |
| DitheringMethod | ditheringMethod | The method of two-dimensional error diffusion dithering. |
ShrinkARGBFormat(int, int, int, int, DitheringMethod)
