subroutine fudge(xfudge, yfudge)
integer*4 xfudge, yfudge

Pascal
procedure fudge(xfudge, yfudge: longint);

DESCRIPTION

fudge specifies fudge values to be added to the dimensions of a graphics port when it is resized.  Typically, this command is used to provide for a window border.  The extra area will appear as part of the port and will be reflected in the size of the drag box as the user sizes it.  fudge is useful in conjunction with stepunit and keepaspect.  With stepunit the port size is constrained to be:

width = xunit∗n + xfudge
height = yunit∗m + yfudge

for integers n and m. With keepaspect the port size is (w, h) where:

(w−xfudge)∗yaspect = (h−yfudge)∗xaspect

It is called at the beginning of a graphics program that will be run with the window manager. If getport is not called or if the system is not running the window manager, fudge is ignored.
