Description

The projectionHint parameter contains information about whether a geometry will cross the coordinate system horizons. If it doesn't, parts of the code that check this and intersect the geometry with the horizons can be omitted. This can dramatically improve performance. Use ISpatialReference3::ProjectionHint to initialize this parameter.

Remarks

By default, ProjectEx will not densify geometries as they are projected. This can lead to the output geometries not reflecting the 'true' shape in the new coordinate system. A straight line in one coordinate system is not necessarily a straight line in a different coordinate system. Set the bAngularDensify parameter if you want to densify the geometries while they are projected.
