SWFDisplayItem::setRatio — Sets the object's ratio
$ratio
)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() .
没有返回值。
This simple example will morph nicely three concentric circles.
