NAME

stepunit - specifies that a graphport should change 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: long);

DESCRIPTION

stepunit specifies that the size of a graphport will change in discrete steps of xunit in the x direction and yunit in the y direction.  It is called at the beginning of a graphics program that will be run with the window manager and takes effect when getport is called.  It is used to resize graphports in units of a standard size (in pixels).  When stepunit is called, the dimensions of the graphport will be:

width = xunit∗n
height = yunit∗m

If getport is not called, or if the system is not running the window manager, stepunit will be ignored. 

SEE ALSO

getport, fudge

NOTE

This command can be used only in immediate mode.
