Other Control Functions

MapViewer provides other useful functions for working with SVG maps. These functions include the following:

• getUserCoordinate(x,y) converts the screen coordinates into the original map data coordinates. This function returns the converted result in an array. The first element of the array is the converted X coordinate, and the second element of the array is the converted Y coordinate.

• getScreenCoordinate(x,y) converts the original map data coordinates into the screen coordinates. This function returns the converted result in an array. The first element of the array is the converted X coordinate, and the second element of the array is the converted Y coordinate.
