This object is a wrapper for the cgMap_Grid routine in IDL. It provides a simple way to allow map grids on images which use a cgMAP object to set up the map projection space. A map coordinate space must be in effect at the time the Draw method of this object is used.

class: out, optional, type=structure Occasionally, it is useful to have an object class definition as a structure variable. Using this output keyword will allow that.
success: out, optional, type=boolean Will be set to 1 on return, if the operation was successful. Otherwise, this value is set to 0. aws the map grid by calling cgMap_Grid. is method allows the user to get various properties of the object.
