Syntax:

ylow = <integer> ;

Option:

-y <pixel>

Range:

0 to 8190. Interpreted as an integer.

Default:

0

Purpose:

Determines the bottom of the image on the screen.

Comments:

The xleft, xright, yhigh and ylow parameters determine the actual pixels to be ren-dered. They do not affect the scene or the view being rendered in any way, but are used to render a rectangular portion of the view.

The rectangle selected must be valid.

That is: 0 <= xleft <xright, and 0 <= ylow < yhigh.

Example:

ylow = 128;
