GetEmitErrors()

bool OGRProjCT::GetEmitErrors ( ) const

inlineoverridevirtual

Whether the transformer will emit CPLError

Reimplemented from OGRCoordinateTransformation.

GetSourceCS()

OGRSpatialReference * OGRProjCT::GetSourceCS ( )

overridevirtual

Fetch internal source coordinate system.

Implements OGRCoordinateTransformation.

GetTargetCS()

OGRSpatialReference * OGRProjCT::GetTargetCS ( )

overridevirtual

Fetch internal target coordinate system.

Implements OGRCoordinateTransformation.

Initialize()

int OGRProjCT::Initialize	(	const OGRSpatialReference *	poSource,
		const OGRSpatialReference *	poTarget,
		const OGRCoordinateTransformationOptions &	options
	)

< Success
< Success

SetEmitErrors()

void OGRProjCT::SetEmitErrors ( bool  )

inlineoverridevirtual

Set if the transformer must emit CPLError

Reimplemented from OGRCoordinateTransformation.

Transform()

int OGRProjCT::Transform ( int  nCount, double *  x, double *  y, double *  z, double *  t, int *  pabSuccess  )

overridevirtual

Transform points from source to destination space.

This method is the same as the C function OCTTransform4D().

Parameters

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

Returns

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

Implements OGRCoordinateTransformation.
