virtual bool OGRProj4CT::GetEmitErrors ( )

inlineoverridevirtual

Whether the transformer will emit CPLError

Reimplemented from OGRCoordinateTransformation.

OGRSpatialReference * OGRProj4CT::GetSourceCS ( )

overridevirtual

Fetch internal source coordinate system.

Implements OGRCoordinateTransformation.

OGRSpatialReference * OGRProj4CT::GetTargetCS ( )

overridevirtual

Fetch internal target coordinate system.

Implements OGRCoordinateTransformation.

virtual void OGRProj4CT::SetEmitErrors ( bool  )

inlineoverridevirtual

Set if the transformer must emit CPLError

Reimplemented from OGRCoordinateTransformation.

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

overridevirtual

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.

References CPLFree, CPLMalloc(), and TransformEx().

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

overridevirtual

Transform an array of points

Parameters

nCount	Number of points
x	Array of nCount x values.
y	Array of nCount y values.
z	Array of nCount z values.
pabSuccess	Output array of nCount value that will be set to TRUE/FALSE

Returns

TRUE or FALSE

Implements OGRCoordinateTransformation.

References CPLAssert, CPLE_AppDefined, CPLError(), CPLRealloc(), and M_PI.
