AVL.RescalePixels(AvlNet.Image, AvlNet.Region, float, float, AvlNet.Image)

Applies linear transformation to pixel values.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax


public static void RescalePixels(
	AvlNet.Image inImage,
	AvlNet.Region inRoi,
	float inA,
	float inB,
	out AvlNet.Image outImage
)

Parameters

inImage
Type: AvlNet.Image
Input image
inRoi
Type: AvlNet.Region
Range of pixels to be processed, or null.
inA
Type: System.Single
Value multiplied
inB
Type: System.Single
Value added
outImage
Type: AvlNet.Image
Output image

Description

The operation applies linear transformation to pixel values.

\[{\forall _{i,j} }{\bf{outImag} }{ {\bf{e} }_{ {\rm{i} },{\rm{j} } } }{\rm{ = } }{\bf{inA} }\cdot{\bf{inImag} }{ {\bf{e} }_{ {\rm{i} },{\rm{j} } } }{\rm{ + } }{\bf{inB} }\]

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

Hardware Acceleration

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.
