Description

void swfdisplayitem->setratio ( float ratio)

警告

本扩展模块是实验性的。该模块的行为,包括其函数的名称以及其它任何关于此模块的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。我们提醒您在使用本扩展模块的同时自担风险。

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().

This simple example will morph nicely three concentric circles.
