)

<ExtensionAttribute>
Public Shared Sub Quantize ( 
	bitmap As Bitmap,
	quantizer As IQuantizer
)

public:
[ExtensionAttribute]
static void Quantize(
	Bitmap^ bitmap, 
	IQuantizer^ quantizer
)

[<ExtensionAttribute>]
static member Quantize : 
        bitmap : Bitmap * 
        quantizer : IQuantizer -> unit 

Parameters

bitmap

Type: System.DrawingBitmap
A Bitmap instance to be quantized.

quantizer

Type: KGySoft.Drawing.ImagingIQuantizer
An IQuantizer implementation to be used for quantizing the specified bitmap.

Usage Note

Note
This method adjusts the degree of parallelization automatically, blocks the caller, and does not support cancellation or reporting progress. Use the BitmapDataExtensions.BeginQuantize or BitmapDataExtensions.QuantizeAsync (in .NET Framework 4.0 and above) methods for asynchronous call and to adjust parallelization, set up cancellation and for reporting progress.

This method quantizes bitmap in place (its original content will be overwritten). To return a new instance use the ConvertPixelFormat extension method instead.

If the PixelFormat or the palette of bitmap is not compatible with the colors of the specified quantizer, then the result may not be correct.

If bitmap has already the same set of colors that the specified quantizer, then it can happen that calling this method does not change bitmap at all.

Tip
To use predefined colors or custom quantization functions use the static methods of the PredefinedColorsQuantizer class. See the Remarks section of its members for details and examples. To use an optimized palette of up to 256 colors adjusted for bitmap see the OptimizedPaletteQuantizer class.
