StuckiColorDithering Class |
Namespace: Accord.Imaging.ColorReduction
The StuckiColorDithering type exposes the following members.
Name | Description | |
---|---|---|
StuckiColorDithering |
Initializes a new instance of the StuckiColorDithering class.
|
Name | Description | |
---|---|---|
Coefficients |
Diffusion coefficients.
(Inherited from ColorErrorDiffusionToAdjacentNeighbors.) | |
ColorTable |
Color table to use for image dithering. Must contain 2-256 colors.
(Inherited from ErrorDiffusionColorDithering.) | |
UseCaching |
Use color caching during color dithering or not.
(Inherited from ErrorDiffusionColorDithering.) |
Name | Description | |
---|---|---|
Apply(Bitmap) |
Perform color dithering for the specified image.
(Inherited from ErrorDiffusionColorDithering.) | |
Apply(UnmanagedImage) |
Perform color dithering for the specified image.
(Inherited from ErrorDiffusionColorDithering.) | |
Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) | |
GetHashCode | Serves as the default hash function. (Inherited from Object.) | |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
ToString | Returns a string that represents the current object. (Inherited from Object.) |
Name | Description | |
---|---|---|
HasMethod |
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.) | |
IsEqual |
Compares two objects for equality, performing an elementwise
comparison if the elements are vectors or matrices.
(Defined by Matrix.) | |
To(Type) | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.
(Defined by ExtensionMethods.) | |
ToT | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.

The image processing routine represents color dithering algorithm, which is based on error diffusion dithering with Stucki coefficients. Error is diffused on 12 neighbor pixels with next coefficients:
| * | 8 | 4 | | 2 | 4 | 8 | 4 | 2 | | 1 | 2 | 4 | 2 | 1 | / 42
The image processing routine accepts 24/32 bpp color images for processing. As a result this routine produces 4 bpp or 8 bpp indexed image, which depends on size of the specified color table - 4 bpp result for color tables with 16 colors or less; 8 bpp result for larger color tables.
Sample usage:
// create color image quantization routine ColorImageQuantizer ciq = new ColorImageQuantizer( new MedianCutQuantizer( ) ); // create 64 colors table Color[] colorTable = ciq.CalculatePalette( image, 64 ); // create dithering routine StuckiColorDithering dithering = new StuckiColorDithering( ); dithering.ColorTable = colorTable; // apply the dithering routine Bitmap newImage = dithering.Apply( image );
