AVL.SubtractFromImage Method

Subtracts a scalar value from each pixel.

Namespace:	AvlNet
Assembly:	AVL.NET.dll

public static void SubtractFromImage(
	AvlNet.Image inImage,
	float inValue,
	out AvlNet.Image outImage
)

Name	Type	Default	Description
inImage	AvlNet.Image		Input image.
inValue	float	50.0f	Value to be subtracted. Default value: 50.0f.
outImage	AvlNet.Image		Output image.

The operation decreases the brightness of the inImage by subtracting a fixed value from each of its pixels.

$\forall_{i,j} \text{\textbf{OutImage} }_{i,j} = \text{\textbf{InImage} }_{i,j} - \text{\textbf{inValue} }$

Whenever the resulting value exceeds the range of pixel values, it is clipped to the nearest proper value.

The SubtractFromImage performed on the sample image with inValue = 50.0.

This operation is optimized for SSE2 technology for pixels of types: UINT8, SINT8, SINT16, REAL.

This operation supports automatic parallelization for multicore and multiprocessor systems.

Hardware acceleration settings may be manipulated with Settings class.
