Modifies the transform of a port such that the edges of the port correspond to the arguments given.
The
set-graphics-port-coordinates
function modifies the transform of the
port
is permanently such that the edges of the port correspond to the values of the arguments.
(set-graphics-port-coordinates port :left -1.0
:top 1.0
:right 1.0
:bottom -1.0)
changes the coordinates of the port so that the point (0 0) is in the exact center of the port and the edges are a unit distance away, with a right-handed coordinate system.
