Syntax:

extensionsize = <integer>;

Option:

-E <size>

Range:

Unbounded integer.

Default:

1

Purpose:

This determines the minimum number of digits in the pix file extension.

Comments:

This is used in conjunction with startextension and byextension to label the files output by the renderer when animating with a different extension from the frame number. If the value given to extensionsize is a float, it is rounded to the nearest lower integer.

Example:

extensionsize = 3;

will create <pixfile>.001 for the first frame of an animation.
