stepun(3G)stepun(3G)NAMEstepun - specifies that a graphics window change size in discrete steps
FORTRAN 77 SPECIFICATION
subroutine stepun(xunit, yunit)
integer*4 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.
DESCRIPTIONstepun specifies the size of the change in a graphics window in discrete
steps of xunit and yunit. Call stepun at the beginning of a graphics
program; it takes effect when you call winope. stepunit resizes graphics
windows in units of a standard size (in pixels). If winope is not
called, stepun is ignored.
