NAME
fudge - specifies fudge values that are added to a graphics
window when it is resized
SPECIFICATION
C fudge(xfudge, yfudge)
long xfudge, yfudge;
FORTRAN subroutine fudge(xfudge, yfudge)
integer*4 xfudge, yfudge
DESCRIPTION
fudge specifies fudge values that are added to the
dimensions of a graphics window when it is resized.
Typically, you use fudge to create window borders. fudge is
useful in conjunction with stepunit and keepaspect.
With stepunit the window size for integers n and m is:
width = xunit*n + xfudge
height = yunit*m + yfudge
With keepaspect the window size is (w, h) where:
(w-xfudge)*yaspect = (h-yfudge)*xaspect
Call fudge at the beginning of a graphics program. If you do
not call winopen, the system ignores fudge.
