This method converts a given coordinate from one coordinate
system to another.
The X and Y coordinates to be converted should be given in
doubleCoordX anddoubleCoordY respectively. After the
method is completed, the doubleCoordX and
doubleCoordY returns the converted coordinates. A handle to
a coordinate system can be obtained using ICoordSys::GetCSHandle().
HRESULT Reproject(
[in] long FromCSHandle,
[in] long ToCSHandle,
[in, out] VARIANT* doubleCoordX,
[in, out] VARIANT* doubleCoordY)
Parameters:
FromCSHandle – Handle to the coordinate system in which the coordinate is given.
ToCSHandle – Handle to the coordinate system to which you want to convert the coordinate.
doubleCoordX – X coordinate.
doubleCoordY – Y coordinate.
Return Values:
The return value obtained from the returned HRESULT can be one of the following:
