Assembly: | AVL.NET.dll |
Syntax

C#
public static void SubtractFromImage ( AvlNet.Image inImage, NullableRef<AvlNet.Region> inRoi, float inValue, AvlNet.Image outImage )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | AvlNet.Image | Input image. | |||
inRoi | AvlNet.NullableRef<AvlNet.Region> | Range of pixels to be processed. Default value: atl::NIL. | |||
inValue | float | 50.0f | Value to be subtracted. Default value: 50.0f. | ||
outImage | AvlNet.Image | Output image. |
Description
The operation decreases the brightness of the inImage by subtracting a fixed value from each of its pixels.
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.
Hardware acceleration settings may be manipulated with Settings class.
