It should be specified relative to the top left corner if page specified relative using DestinationPropertiesBase#page or relative to the bottom left corner if page specified using DestinationPropertiesBase#pageIndex. See Destination description for details.
Optionalzoom?: numberThe zoom factor of the document window, unchanged if null or zero.
Display the page designated by DestinationPropertiesBase#page, with the coordinates (left, top) positioned at the upper-left corner of the window and the contents of the page magnified by the factor zoom. A null value for any of the parameters left, top, or zoom specifies that the current value of that parameter is to be retained unchanged. A zoom value of 0 has the same meaning as a null value.
