Member Function Documentation

OGRSpatialReference * OGRProj4CT::GetSourceCS

(

)

[virtual]

Fetch internal source coordinate system.

Implements OGRCoordinateTransformation.

OGRSpatialReference * OGRProj4CT::GetTargetCS

(

)

[virtual]

Fetch internal target coordinate system.

Implements OGRCoordinateTransformation.

int OGRProj4CT::Transform	(	int	nCount,
		double *	x,
		double *	y,
		double *	z = NULL
	)			[virtual]

Transform points from source to destination space.

This method is the same as the C function OCTTransform().

The method TransformEx() allows extended success information to be captured indicating which points failed to transform.

Parameters:

	nCount	number of points to transform.
	x	array of nCount X vertices, modified in place.
	y	array of nCount Y vertices, modified in place.
	z	array of nCount Z vertices, modified in place.

Returns:

TRUE on success, or FALSE if some or all points fail to transform.

Implements OGRCoordinateTransformation.

int OGRProj4CT::TransformEx	(	int	nCount,
		double *	x,
		double *	y,
		double *	z = NULL,
		int *	pabSuccess = NULL
	)			[virtual]

Transform points from source to destination space.

This method is the same as the C function OCTTransformEx().

Parameters:

	nCount	number of points to transform.
	x	array of nCount X vertices, modified in place.
	y	array of nCount Y vertices, modified in place.
	z	array of nCount Z vertices, modified in place.
	pabSuccess	array of per-point flags set to TRUE if that point transforms, or FALSE if it does not.

Returns:

TRUE if some or all points transform successfully, or FALSE if if none transform.

Implements OGRCoordinateTransformation.
