map( ) — move and resize a polygon

Synopsis

GD::Polygon::map(srcLeft, srcTop, srcRight, srcBottom,                   destLeft, destTop, destRight, destBottom)

This method will scale an existing polygon to fit a region, changing the values of all of the vertices within the polygon. The first four parameters define the bounding box of the source area and the last four define the bounding box of the destination area.
