The GDRAW('IMAGE',
. . .) function displays the specified image within opposing pairs
of coordinates. The format of the external image file varies between
operating environments. The (x1, y1) coordinate pair specifies one
corner of the image, and the (x2, y2) coordinate pair specifies the
opposite corner of the image. The
style parameter must be either 'TILE' to copy the image as many times
as necessary to fill the area; or 'FIT' to stretch one instance of
the image to fill the area.
