Flash movie coordinates are measured in Flash movie pixels, which are determined by a movie's original size when it was created in Flash. For the purposes of calculating Flash movie coordinates, point(0,0) of a Flash movie is always at its upper-left corner. (The sprite icon's originPoint property isn't used to calculate movie coordinates; it's used only for rotation and scaling.)

The FlashToStage and the corresponding stageToFlash methods are helpful for determining which Flash movie coordinate is directly over a Presentation window coordinate. When a Flash movie is positioned in the Presentation window, its upper-left corner, expressed as point(0,0), won't always be at the upper-left corner of Authorware's Presentation window, which is also expressed as point(0,0). As a Flash sprite is stretched, its scaleMode property will affect the way its coordinates shift over the Presentation window. Also, Flash movies can be scaled and rotated, further complicating the task of matching coordinates. The FlashToStage and stageToFlash methods make it possible to determine with a high degree of accuracy which coordinate in a Flash movie is directly over a coordinate in Authorware's Presentation window.
