Converts the coordinates of a point from global coordinates to the local coordinates of the current graphics port (basic or color).

void GlobalToLocal (
    Point *pt
);

pt

A pointer to a point expressed in global coordinates (where the upper-left corner of the main screen has coordinates [0,0]). On return, this point is converted to local coordinates.

DISCUSSION

The GlobalToLocal procedure takes a point expressed in global coordinates (where the upper-left corner of the main screen has coordinates [0,0]) and converts it into the local coordinates of the current graphics port.
