subroutine, public shapelib::shpcomputeextents ( type(shpobject), target  psobject ) It recomputes the extents of a shape. This subroutine replaces the existing values of the dfXMin, dfYMin, dfZMin, dfMMin, dfXMax, dfYMax, dfZMax, and dfMMax with updated values based on the current set of vertices for the shape. It is automatically called by shpcreateobject, but if the vertices of an existing object are altered it should be called again to fix up the extents. Parameters psobject shape object to update Definition at line 643 of file shapelib.F90.
