Methods

Blend(Configuration, Span<TPixel>, ReadOnlySpan<TPixel>, ReadOnlySpan<TPixel>, ReadOnlySpan<float>)

Blends 2 rows together

public void Blend(Configuration configuration, Span<TPixel> destination, ReadOnlySpan<TPixel> background, ReadOnlySpan<TPixel> source, ReadOnlySpan<float> amount)

Parameters

configuration Configuration

Configuration to use internally

destination Span<TPixel>

the destination span

background ReadOnlySpan<TPixel>

the background span

source ReadOnlySpan<TPixel>

the source span

amount ReadOnlySpan<float>

A span with values between 0 and 1 indicating the weight of the second source vector. At amount = 0, "background" is returned, at amount = 1, "source" is returned.

Blend(TPixel, TPixel, float)

Blend 2 pixels together.

public abstract TPixel Blend(TPixel background, TPixel source, float amount)

Parameters

background TPixel

The background color.

source TPixel

The source color.

amount float

A value between 0 and 1 indicating the weight of the second source vector. At amount = 0, "background" is returned, at amount = 1, "source" is returned.

Returns

TPixel

The final pixel value after composition.
