GrapeCity.Documents.Imaging.GcBitmap.ToIndexed8bppBitmap
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 Indexed8bppBitmapParameters
| 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 Indexed8bppBitmapParameters
| 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 Indexed8bppBitmap ToIndexed8bppBitmap(DitheringMethod ditheringMethod)Public Function ToIndexed8bppBitmap(ditheringMethod As DitheringMethod) As Indexed8bppBitmapParameters
| Type | Name | Description |
