NAME

fudge − specifies fudge values added to a graphics window

SPECIFICATION

C
fudge(xfudge, yfudge)
long xfudge, yfudge;

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

Pascal
procedure fudge(xfudge, yfudge: longint);

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 that runs under the window manager.  If you do not call winopen, or if the window manager is not running, the system ignores fudge.
