Member Function Documentation

virtual bool ml::LUTFRescale::getAutoSourceRange ( void ) const [inline, virtual]

Get auto source index range flag.

Reimplemented from ml::LUTFunction.

virtual int ml::LUTFRescale::getNativeMaxIndex ( void ) const [virtual]

Get native maximum index.

Reimplemented from ml::LUTFunction.

virtual double ml::LUTFRescale::getNativeMaxValue ( void ) const [virtual]

Get native maximum LUT value.

Reimplemented from ml::LUTFunction.

virtual int ml::LUTFRescale::getNativeMinIndex ( void ) const [virtual]

Get native minimum index.

Reimplemented from ml::LUTFunction.

virtual double ml::LUTFRescale::getNativeMinValue ( void ) const [virtual]

Get native minimum LUT value.

Reimplemented from ml::LUTFunction.

virtual double ml::LUTFRescale::getSourceMax ( void ) const [virtual]

Get maximum source index.

virtual double ml::LUTFRescale::getSourceMin ( void ) const [virtual]

Get minimum source index.

virtual double ml::LUTFRescale::getTargetMax ( void ) const [inline, virtual]

Get maximum target index.

Definition at line 70 of file mlLUTFRescale.h.

virtual double ml::LUTFRescale::getTargetMin ( void ) const [inline, virtual]

Get minimum target index.

Definition at line 67 of file mlLUTFRescale.h.

virtual LUTVisualType ml::LUTFRescale::getVisualType ( void ) const [virtual]

Get LUT visual type.

Reimplemented from ml::LUTFunction.

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

Return true if the LUT function is valid.

Reimplemented from ml::LUTFunction.

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

virtual bool ml::LUTFRescale::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::LUTFRescale::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::LUTFRescale::setAutoSourceRange ( bool autoSourceRange ) [inline, virtual]

Set auto source index range flag.

Definition at line 55 of file mlLUTFRescale.h.

References ml::LUTFunction::changed().

virtual void ml::LUTFRescale::setInputLUT ( const LUTFunction * inLUT ) [virtual]

Set input LUT, set relative flag to true if input LUT is relative.

virtual void ml::LUTFRescale::setRelative ( bool relative ) [virtual]

Set/reset relative flag, can only be set if input LUT is absolute.

A relative LUT can not be converted to an absolute LUT.

Reimplemented from ml::LUTFunction.
