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.
