Positioning Page Elements with Page Coordinate
System Units
Page element extents specified through the API are expressed in Page Coor-
dinate System (PCS) units. The origin (0,0) of this system is located at the
upper-left corner of the paper. Its exact location depends on the current left
and top margins. Unlike the coordinate system that is used on a map, the Y
values increase in the downward direction and the X values increase to the
right. Like the device unit type, the default PCS unit type is a pixel.
