Syntax:

xleft = <integer> ;

Option:

-x <pixel>

Range:

0 to 8190 (Must be less than xright). Interpreted as an integer.

Default:

0

Purpose:

Determines the left edge 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:

xleft = 128;
