stepunit(3G)

NAME
     stepunit - specifies that a graphics window change size in discrete steps

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

PARAMETERS
     xunit   expects the amount of change per unit in the x direction.  The
             amount is measured in pixels.

     yunit   expects the amount of change per unit in the y direction.  The
             amount is measured in pixels.

DESCRIPTION
     stepunit specifies the size of the change in a graphics window in
     discrete steps of xunit and yunit. Call stepunit at the beginning of a
     graphics program; it takes effect when you call winopen.  stepunit
     resizes graphics windows in units of a standard size (in pixels).  If
     winopen is not called, stepunit is ignored.
