SWFDisplayItem::setRatio

(PHP 5 <= 5.3.0, PECL ming SVN)

SWFDisplayItem::setRatio — Sets the object's ratio

说明

void SWFDisplayItem::setRatio ( float $ratio )

Warning

此函数是实验性的。此函数的表象，包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。使用本函数风险自担。

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() .

返回值

没有返回值。

范例

This simple example will morph nicely three concentric circles.
