virtual void ml::LUTFBlend::clearLutData ( void ) const [protected, virtual]

Clear LUT data objects after rendering.

virtual LUTVisualType ml::LUTFBlend::getRenderType ( LUTDataBase * lutData ) const [inline, protected, virtual]

Get visual type used for rendering.

This method is called by render() and renderRescaled() to initialize the LUT iterator object appropriate for a pair of source/target visual types. By returning the visual type of lutData, we always render directly in the visual type requested.

Reimplemented from ml::LUTFunction.

Definition at line 116 of file mlLUTFBlend.h.

virtual bool ml::LUTFBlend::isValid ( void ) const [virtual]

Return true if the LUT function is valid.

virtual bool ml::LUTFBlend::renderLUTNative	(	LUTDataBase *	lutData,
		LUTIteratorBase *	lutIterator
	)		const `[protected, virtual]`

Render the lookup table into lutData using lutIterator to access and increment the LUT pointers.

Both lutData and lutIterator should be type-cast to a derived, type specific class pointer, according to lutData->getDataType(). Return true if successful.

Implements ml::LUTFunction.

virtual bool ml::LUTFBlend::renderLUTRescaled	(	LUTDataBase *	lutData,
		LUTIteratorBase *	lutIterator,
		double	minIndex,
		double	maxIndex
	)		const `[protected, virtual]`

Render rescaled LUT into lutData using lutIterator to access and increment the LUT pointers.

Both lutData and lutIterator should be type-cast to a derived, type specific class pointer, according to lutData->getDataType(). The LUT is rendered for range minIndex .. maxIndex, but resampled to the index range specified in lutData. Return true if successful.

Reimplemented from ml::LUTFunction.

virtual bool ml::LUTFBlend::renderRescaled	(	LUTDataBase *	lutData,
		double	minIndex,
		double	maxIndex
	)		const `[virtual]`

Render rescaled LUT in (previously initialized) LUTData object.

virtual void ml::LUTFBlend::setBlendingSteps ( int numBlendingSteps ) [virtual]

Set number of blending steps (= number of rows/layers in output 2/3D-LUT, min = 2)
