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

Blends 2 rows together

Declaration

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

Parameters

Type	Name	Description
Configuration	configuration	Configuration to use internally
Span<TPixel>	destination	the destination span
ReadOnlySpan<TPixel>	background	the background span
