keepas(3G)keepas(3G)NAMEkeepas - specifies the aspect ratio of a graphics window
FORTRAN SPECIFICATION
subroutine keepas(x, y)
integer*4 x, y
PARAMETERS
x expects the horizontal proportion of the aspect ratio. The value must
be between 1 and 32767 ($7fff), inclusive.
y expects the vertical proportion of the aspect ratio. The value must
be between 1 and 32767 ($7fff), inclusive.
DESCRIPTIONkeepas specifies the aspect ratio of a graphics window. Call it at the
beginning of a graphics program. It takes effect when you call winope.
The resulting graphics window maintains the aspect ratio specified in
keepas, even if it changes size.
For example, keepas(1, 1) always results in a square graphics window.
You can also call keepas in conjunction with wincon to modify the
enforced aspect ratio after the window has been created.
