Method Detail

readShapePoints

public static int readShapePoints(ByteBuffer buffer,
                                  PolylineArray results)

Reads through a ByteBuffer and converts it to one or more polylines in the given PolylineArray. From there you can decide how to process it - as a point, polygon, etc. This does not necessarily faithfully reproduce the original shape - arcs are plotted as lines at 10 degree intervals, for example.
