CreateLogarithmLut
Creates Look Up Table for logarithm operation on image pixels.
Syntax
void avl::CreateLogarithmLut ( atl::Optional<const float&> inScale, float inOffset, bool inNormalizeZero, const avl::PlainType::Type& inOutputType, avl::PixelLut& outLut )
Parameters
| Name | Type | Default | Description | |
|---|---|---|---|---|
 |
inScale | Optional<const float&> | NIL | Scaling factor (default: 255) |
|
inOffset | float | Offset factor | |
|
inNormalizeZero | bool | Specifies whether the output range should be rescaled to start from 0 | |
|
inOutputType | const PlainType::Type& | ||
 |
outLut | PixelLut& |
Description
This operation will create LookUp Table with precalculated values of logarithm operation on all pixel values of type defined in inOutputType. Such LUT can be reused across multiple ApplyPixelLut usages. This filter can create LUTs only for following types: INT8, UINT8, INT16, UINT16.
Remarks
Standard operations like PowerImage, CorrectGamma and LogarithmImage for images of type Int32 and Real are available in Image Point Transforms category.
