◆ ApplyGammaExponentCorrection()

template<class P >

static void pcl::GeometricTransformation::ApplyGammaExponentCorrection	(	typename P::sample *	samples,
		size_type	length,
		double	gamma,
		AbstractImage::ThreadData &	threadData,
		int	maxProcessors = `PCL_MAX_PROCESSORS`
	)

inlinestatic

Applies a gamma correction function to a block of pixel sample values.

Parameters

[in,out]	samples	Pointer to the start of a contiguous block of pixel sample values. On input, these values must be expressed in a nonlinear color space with the specified gamma exponent. On output, these values will be expressed in a linear color space.
	length	Number of pixel sample values to process.
	gamma	The gamma exponent of the nonlinear color space. A value gamma > 0 must be specified.
	threadData	Reference to an AbstractImage::ThreadData object for thread control and monitoring.
	maxProcessors	Maximum number of parallel threads to use. The default value does not impose a practical limit.

Definition at line 232 of file GeometricTransformation.h.

◆ ApplyInverseGammaExponentCorrection()

template<class P >

static void pcl::GeometricTransformation::ApplyInverseGammaExponentCorrection	(	typename P::sample *	samples,
		size_type	length,
		double	gamma,
		AbstractImage::ThreadData &	threadData,
		int	maxProcessors = `PCL_MAX_PROCESSORS`
	)

		int	maxProcessors = `PCL_MAX_PROCESSORS`
	)

inlinestatic

Applies an inverse sRGB gamma correction function to a block of pixel sample values.

Parameters

[in,out]	samples	Pointer to the start of a contiguous block of pixel sample values. On input, these values must be expressed in a linear color space. On output, these values will be expressed in the sRGB color space.
	length	Number of pixel sample values to process.
	threadData	Reference to an AbstractImage::ThreadData object for thread control and monitoring.
	maxProcessors	Maximum number of parallel threads to use. The default value does not impose a practical limit.

		size_type	length,
		AbstractImage::ThreadData &	threadData,
		int	maxProcessors = `PCL_MAX_PROCESSORS`
	)

inlinestatic

Applies an sRGB gamma correction function to a block of pixel sample values.

Parameters

[in,out]	samples	Pointer to the start of a contiguous block of pixel sample values. On input, these values must be expressed in the sRGB color space. On output, these values will be expressed in a linear color space.
	length	Number of pixel sample values to process.
	threadData	Reference to an AbstractImage::ThreadData object for thread control and monitoring.
	maxProcessors	Maximum number of parallel threads to use. The default value does not impose a practical limit.

◆ GetNewSizes()

virtual void pcl::GeometricTransformation::GetNewSizes	(	int &	width,
		int &	height
	)		const

pure virtual

Predicts transformed image dimensions.

Parameters

[in,out]	width	Reference to a variable whose value is a horizontal dimension in pixels (width). On output, it will receive the predicted horizontal dimension after the transformation.
[in,out]	height	Reference to a variable whose value is a vertical dimension in pixels (height). On output, it will receive the predicted vertical dimension after the transformation.

Note: This is a pure virtual member function that must be reimplemented in every derived class.

Implemented in pcl::Translation, pcl::Rotation, pcl::Resample, pcl::IntegerResample, pcl::Crop, pcl::AstrometricReprojection, pcl::PolarTransformBase, pcl::VerticalMirror, pcl::HorizontalMirror, pcl::Rotate90CCW, pcl::Rotate90CW, and pcl::Rotate180.

◆ operator=() [1/2]

GeometricTransformation& pcl::GeometricTransformation::operator= ( const GeometricTransformation & )

default

Referenced by pcl::InterpolatingGeometricTransformation::operator=().

◆ operator=() [2/2]

GeometricTransformation& pcl::GeometricTransformation::operator= ( GeometricTransformation && )

default
