NAME

stepunit − specifies that a graphics window changes size in discrete steps

SPECIFICATION

C
stepunit(xunit, yunit)
long xunit, yunit;

FORTRAN
subroutine stepun(xunit, yunit)
integer*4 xunit, yunit

Pascal
procedure stepunit(xunit, yunit: longint);

DESCRIPTION

stepunit specifies that the size of a graphics window changes in discrete steps of xunit in the x direction and yunit in the y direction.  Call stepunit at the beginning of a graphics program that is run in the window manager; it takes effect when winopen is called.  stepunit resizes graphics windows in units of a standard size (in pixels).  When stepunit is called, the dimensions of the graphics window are:

width = xunit∗n
height = yunit∗m

If winopen is not called, or if the system is not running the window manager, stepunit is ignored.
