stepunit(3G) stepunit(3G)
NAME
stepunit - specifies that a graphics window change size in
discrete steps
SPECIFICATION
C stepunit(xunit, yunit)
long xunit, yunit;
FORTRAN subroutine stepun(xunit, yunit)
integer*4 xunit, yunit
DESCRIPTION
stepunit specifies that the size of a graphics window change
in discrete steps of xunit in the x direction and yunit in
the y direction. Call stepunit at the beginning of a
graphics program; 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.
