FIL.DivideImage

Divides each pixel by a scalar value.

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

C++
C#
 
public static void DivideImage
(
	FilNet.Image inImage,
	NullableRef<FilNet.Region> inRoi,
	float inValue,
	FilNet.Image outImage
)

Parameters

Name Type Range Default Description
inImageFilNet.ImageInput image.
inRoiFilNet.NullableRef<FilNet.Region>Range of pixels to be processed. Default value: ftl::NIL.
inValuefloat2.0fDivisor. Default value: 2.0f.
outImageFilNet.ImageOutput image.

Description

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

\forall_{i,j} \text{\textbf{OutImage} }_{i,j} = \frac{\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.

Examples

DivideImage performed on the sample image with inValue = 2.0.

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.

Errors

List of possible exceptions:

Error type Description
DomainError Division by zero in DivideImage.
DomainError Region exceeds an input image in DivideImage.
