Reimplemented from pcl::ImageTransformation.

◆ Center()

DPoint pcl::Rotation::Center ( ) const

inline

Returns the center of rotation. The returned point coordinates are measured in pixels in the image coordinate system.

Definition at line 143 of file Rotation.h.

◆ CenterX()

double pcl::Rotation::CenterX ( ) const

inline

Returns the horizontal coordinate of the center of rotation, measured in pixels in the image coordinate system.

Definition at line 152 of file Rotation.h.

◆ CenterY()

double pcl::Rotation::CenterY ( ) const

inline

Returns the vertical coordinate of the center of rotation, measured in pixels in the image coordinate system.

Definition at line 161 of file Rotation.h.

◆ DisableUnclippedRotation()

void pcl::Rotation::DisableUnclippedRotation ( bool disable = true )

inline

Disables unclipped rotations for this object. See IsUnclipped() for information on unclipped rotations.

Definition at line 213 of file Rotation.h.

◆ EnableUnclippedRotation()

void pcl::Rotation::EnableUnclippedRotation ( bool enable = true )

inline

Enables unclipped rotations for this object. See IsUnclipped() for information on unclipped rotations.

Definition at line 204 of file Rotation.h.

◆ FillValues()

const DVector& pcl::Rotation::FillValues ( ) const

inline

Returns the current vector of per-channel filling values for uncovered image regions.

See the documentation for SetFillValues() for more information.

Definition at line 224 of file Rotation.h.

◆ GetNewSizes()

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

overridevirtual

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.

Implements pcl::GeometricTransformation.

◆ IsUnclipped()

bool pcl::Rotation::IsUnclipped ( ) const

inline

Returns true iff this transformation will preserve the entire target image without clipping any pixels after rotating it.

An unclipped rotation ignores the specified rotation center coordinates (see CenterX() and CenterY(), as well as the class constructor) and rotates images with respect to their geometric centers. To accommodate all rotated pixels in the result, the unclipped rotated image will always be bigger than the original, except for the trivial cases of rotations by 0 and 180 degrees.

Definition at line 195 of file Rotation.h.

◆ SetAngle()

void pcl::Rotation::SetAngle ( double rads )

inline

Sets the rotation angle in radians.

Definition at line 134 of file Rotation.h.

◆ SetCenter() [1/2]

void pcl::Rotation::SetCenter ( const DPoint & center )

inline

Sets the center of rotation. The specified center point coordinates must be expressed in pixels in the image coordinate system.

Definition at line 170 of file Rotation.h.

◆ SetCenter() [2/2]

void pcl::Rotation::SetCenter	(	double	xc,
		double	yc
	)

inline

Sets the center of rotation to the specified coordinates xc and yc, which must be expressed in pixels in the image coordinate system.

Definition at line 179 of file Rotation.h.

◆ SetFillValues()

void pcl::Rotation::SetFillValues ( const DVector & fillValues )

inline

Sets a vector of per-channel filling values for uncovered image regions.

Uncovered regions result when an image is rotated by non-orthogonal angles.

By default, there are no filling values defined (and hence the returned vector is empty by default). When the Rotation instance is executed and a filling value is not defined for a channel of the target image, uncovered regions are filled with the minimum sample value in the native range of the image (usually zero).
