FIL.RescalePixels
Applies linear transformation to pixel values.
| Namespace: | FilNet |
|---|---|
| Assembly: | FIL.NET.dll |
Syntax
public static void RescalePixels ( FilNet.Image inImage, NullableRef<FilNet.Region> inRoi, float inA, float inB, FilNet.Image outImage )
Parameters
| Name | Type | Range | Default | Description | |
|---|---|---|---|---|---|
 | inImage | FilNet.Image | Input image. | ||
| inRoi | FilNet.NullableRef<FilNet.Region> | Range of pixels to be processed. Default value: ftl::NIL. | ||
| inA | float | 1.0f | Value multiplied. Default value: 1.0f. | |
| inB | float | 0.0f | Value added. Default value: 0.0f. | |
 | outImage | FilNet.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.
Errors
List of possible exceptions:
| Error type | Description |
|---|---|
| DomainError | Region exceeds an input image in RescalePixels. |
