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.

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

Parameters

processor TPaletteDitherImageProcessor

The palette dithering processor.

source ImageFrame<TPixel>

The source image.

bounds Rectangle

The region of interest bounds.

Type Parameters

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.

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

Parameters

quantizer TFrameQuantizer

The frame quantizer.

source ImageFrame<TPixel>

The source image.

destination IndexedImageFrame<TPixel>

The destination quantized frame.

bounds Rectangle

The region of interest bounds.

Type Parameters

TFrameQuantizer

The type of frame quantizer.

TPixel

The pixel format.

Equals(ErrorDither)

Indicates whether the current object is equal to another object of the same type.

public bool Equals(ErrorDither other)

Parameters

other ErrorDither

An object to compare with this object.

Returns

bool

true if the current object is equal to the other parameter; otherwise, false.

Equals(IDither?)

Indicates whether the current object is equal to another object of the same type.

public bool Equals(IDither? other)

Parameters

other IDither

An object to compare with this object.

Returns

bool

true if the current object is equal to the other parameter; otherwise, false.

Equals(object?)

Indicates whether this instance and a specified object are equal.

public override bool Equals(object? obj)

Parameters

obj object

The object to compare with the current instance.

Returns

bool

true if obj and this instance are the same type and represent the same value; otherwise, false.

GetHashCode()

Returns the hash code for this instance.

public override int GetHashCode()

Returns

int

A 32-bit signed integer that is the hash code for this instance.
