ToIndexed8bppBitmap Method

ToIndexed8bppBitmap(int, bool)

Creates an opaque Indexed8bppBitmap from the current image using the Octree quantizer algorithm.

Declaration

public Indexed8bppBitmap ToIndexed8bppBitmap(int maxColors, bool appendTransparentColor = false)

Public Function ToIndexed8bppBitmap(maxColors As Integer, Optional appendTransparentColor As Boolean = False) As Indexed8bppBitmap

Parameters

Type	Name	Description
int	maxColors	The maximum number of opaque colors in the palette, from 8 to 256.
bool	appendTransparentColor	Indicates if a transparent color should be added to the palette, if the image is not opaque and the number of opaque colors is less than 256.

Returns

Type	Description
Indexed8bppBitmap	A new instance of Indexed8bppBitmap.

ToIndexed8bppBitmap(uint[], DitheringMethod, bool)

Creates an opaque Indexed8bppBitmap from the current image using the specified palette.

Declaration

public Indexed8bppBitmap ToIndexed8bppBitmap(uint[] palette, DitheringMethod ditheringMethod, bool appendTransparentColor = false)

Public Function ToIndexed8bppBitmap(palette As UInteger(), ditheringMethod As DitheringMethod, Optional appendTransparentColor As Boolean = False) As Indexed8bppBitmap

Parameters

Type	Name	Description
uint[]	palette	The palette with opaque colors for the new image (colors are in 32-bit ARGB format). Elements with index 256 and above are ignored.
DitheringMethod	ditheringMethod	The method of two-dimensional error diffusion dithering.
bool	appendTransparentColor	Indicates if a transparent color should be added to the palette, if the image is not opaque and the number of opaque colors is less than 256.

Returns

Type	Description
Indexed8bppBitmap	A new instance of Indexed8bppBitmap.

ToIndexed8bppBitmap(DitheringMethod)

Creates an Indexed8bppBitmap from the current image.

Declaration

Public Function ToIndexed8bppBitmap(ditheringMethod As DitheringMethod) As Indexed8bppBitmap

Parameters

Type	Name	Description
DitheringMethod	ditheringMethod	The method of two-dimensional error diffusion dithering.

Returns

Type	Description
Indexed8bppBitmap	A new instance of Indexed8bppBitmap.
