# SWFDisplayItem->setRatio()

(PHP 4 >= 4.0.5)

SWFDisplayItem->setRatio() — Sets the object's ratio

### Description

SWFDisplayItem
void setRatio ( float `$ratio` )
Warning

This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function 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.
