DivideImage
Header: | AVL.h |
---|---|
Namespace: | avl |
Divides each pixel by a scalar value.
Syntax
void avl::DivideImage ( const avl::Image& inImage, atl::Optional<const avl::Region&> inRoi, float inValue, avl::Image& outImage )
Parameters
Name | Type | Default | Description | |
---|---|---|---|---|
inImage | const Image& | Input image | ||
inRoi | Optional<const Region&> | NIL | Range of pixels to be processed | |
inValue | float | 2.0f | Divisor | |
outImage | Image& | Output image |
In-place Processing
This function supports in-place data processing - you can pass the same reference to inImage and outImage

Description
The operation decreases the brightness of the inImage dividing each of its pixels by a fixed value.
Whenever the resulting value exceeds the range of pixel values, it is clipped to the nearest proper value.
Examples
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.
Errors
List of possible exceptions:
Error type | Description |
---|---|
DomainError | Division by zero in DivideImage. |
DomainError | Region exceeds an input image in DivideImage. |
