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.
