SWFDisplayItem::setRatio

Sets the object's ratio

Description

void SWFDisplayItem::setRatio ( float $ratio )

Warning

This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk.

swfdisplayitem::setratio sets the object's ratio to ratio. Obviously only useful for morphs.

The object may be a swfshape, a swfbutton, a swftext or a swfsprite object. It must have been added using the swfmovie::add.

Return Values

No value is returned.

Examples

This simple example will morph nicely three concentric circles.
