MapInverse Method
The MapInverse method transforms map coordinates from Cartesian (x, y) coordinates to longitude and latitude, using the map projection associated with the graphic.
Example
See the example for the MapForward Method.
Syntax
Result = graphic.MapInverse(X [, Y] [, /RADIANS])
Return Value
The result is a (2, n) array containing the longitude/latitude coordinates.
Arguments
X
An n-element vector containing the x values. If the Y argument is omitted, X must be a (2, n) array of X and Y pairs.
Y
An n-element vector containing y values. If this argument is omitted, X must be a (2, n) array of X and Y pairs.
Keywords
RADIANS
Set this keyword to indicate that the returned longitude and latitude coordinates should be expressed in radians. By default, returned coordinates are expressed in degrees.
