Methods

ApplyPaletteDither<TPaletteDitherImageProcessor, TPixel>(in TPaletteDitherImageProcessor, ImageFrame<TPixel>, Rectangle)

Transforms the image frame applying a dither matrix. This method should be treated as destructive, altering the input pixels.

Declaration

public readonly void ApplyPaletteDither<TPaletteDitherImageProcessor, TPixel>(in TPaletteDitherImageProcessor processor, ImageFrame<TPixel> source, Rectangle bounds)
    where TPaletteDitherImageProcessor : struct, IPaletteDitherImageProcessor<TPixel> where TPixel : struct, IPixel<TPixel>

Parameters

Type	Name	Description
TPaletteDitherImageProcessor	processor	The palette dithering processor.
ImageFrame<TPixel>	source	The source image.
Rectangle	bounds	The region of interest bounds.

Type Parameters

Name	Description
TPaletteDitherImageProcessor	The type of palette dithering processor.
TPixel	The pixel format.

ApplyQuantizationDither<TFrameQuantizer, TPixel>(ref TFrameQuantizer, ImageFrame<TPixel>, IndexedImageFrame<TPixel>, Rectangle)

Transforms the quantized image frame applying a dither matrix. This method should be treated as destructive, altering the input pixels.

Declaration

public readonly void ApplyQuantizationDither<TFrameQuantizer, TPixel>(ref TFrameQuantizer quantizer, ImageFrame<TPixel> source, IndexedImageFrame<TPixel> destination, Rectangle bounds)
    where TFrameQuantizer : struct, IQuantizer<TPixel> where TPixel : struct, IPixel<TPixel>

Parameters

Type	Name	Description
TFrameQuantizer	quantizer	The frame quantizer.
ImageFrame<TPixel>	source	The source image.
IndexedImageFrame<TPixel>	destination	The destination quantized frame.
Rectangle	bounds	The region of interest bounds.

Type Parameters

Name	Description
TFrameQuantizer	The type of frame quantizer.
TPixel	The pixel format.
