PrintOMatic uses the same basic coordinate system as the Director stage, which places (0,0) at the top-left corner. Coordinate values increase towards the bottom and right sides of the page. All drawing coordinates are specified in points, with 72 points to the inch. All drawing coordinates for objects in PrintOMatic are relative to the page margins, which are set using the mSetMargins method. The drawing area defined by the margins applies to the entire document.
Calling mPageSetup or mSetLandscapeMode may change the size of the page, thereby changing the coordinate system, as well as the values returned by mGetPageWidth and mGetPageHeight. If you store these values in Lingo variables, be sure to reset them after calling mPageSetup or mSetLandscapeMode.
