ml::LUTFPrimitive::ML_CLASS_HEADER ( LUTFPrimitive ) [protected]

template<typename T >

bool ml::LUTFPrimitive::renderLUT	(	LUTData< T > *	lutData,
		LUTIterator< T > *	lutIterator,
		double	center,
		double	width,
		double	edgeWidth
	)		const `[protected]`

Render a LUT primitive (as selected by the _shape member variable) into lutData using lutIterator to access and increment the LUT pointers.

Return true if successful.

virtual bool ml::LUTFPrimitive::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::LUTFPrimitive::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 void ml::LUTFPrimitive::setBaseValue ( double baseValue ) [inline, virtual]

Set base value.
