B.4 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.
