Graphic primitive transformations MapTransformation supports transformation into any of the map projections of graphic primitives using the data space primitive drawing routines NhlDataPolygon , NhlDataPolyline , and NhlDataPolymarker . Depending on the setting of the boolean resource mpGreatCircleLinesOn , lines or edges spanning the space between the user-supplied points of a polyline or polygon may be transformed in two different ways. The MapTransformation object does not define any support functions, but inherits all the support functions available to its superclass. Range checking is inadequate for a number of the MapTransformation resources including mpLambertMeridianF , mpLambertParallel2F , mpLambertParallel1F , mpCenterLatF , and mpCenterLonF . This occurs in certain situations that have so far proved to be difficult to pin down.
More work is required.
