INPUT

OUTPUT

none

RETURN VALUE

The position object on success, NULL on failure

DESCRIPTION

A position object is used to track movement of the pointer in an image; thus, it was designed to be used in conjunction with an image object.

The position object displays values in an (X x Y) or (X x Y = Z) format, where X and Y display the location of the pointer in the image object, and the optional Z is the pixel value of the image at that location. When the latter format is used with an RGB image, the format is modified to be ( X x Y = R G B).
