# SWFDisplayItem->setRatio

(no version information, might be only in CVS)

SWFDisplayItem->setRatio -- Sets the object's ratio

## Description

void swfdisplayitem->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().

This simple example will morph nicely three concentric circles.

Example 1. swfdisplayitem->setname() example
`<?php $p = new SWFMorph(); $g = new SWFGradient(); $g->addEntry(0.0, 0, 0, 0); $g->addEntry(0.16, 0xff, 0xff, 0xff); $g->addEntry(0.32, 0, 0, 0); $g->addEntry(0.48, 0xff, 0xff, 0xff); $g->addEntry(0.64, 0, 0, 0); $g->addEntry(0.80, 0xff, 0xff, 0xff); $g->addEntry(1.00, 0, 0, 0); $s = $p->getShape1(); $f = $s->addFill($g, SWFFILL_RADIAL_GRADIENT); $f->scaleTo(0.05); $s->setLeftFill($f); $s->movePenTo(-160, -120); $s->drawLine(320, 0); $s->drawLine(0, 240); $s->drawLine(-320, 0); $s->drawLine(0, -240); $g = new SWFGradient(); $g->addEntry(0.0, 0, 0, 0); $g->addEntry(0.16, 0xff, 0, 0); $g->addEntry(0.32, 0, 0, 0); $g->addEntry(0.48, 0, 0xff, 0); $g->addEntry(0.64, 0, 0, 0); $g->addEntry(0.80, 0, 0, 0xff); $g->addEntry(1.00, 0, 0, 0); $s = $p->getShape2(); $f = $s->addFill($g, SWFFILL_RADIAL_GRADIENT); $f->scaleTo(0.05); $f->skewXTo(1.0); $s->setLeftFill($f); $s->movePenTo(-160, -120); $s->drawLine(320, 0); $s->drawLine(0, 240); $s->drawLine(-320, 0); $s->drawLine(0, -240); $m = new SWFMovie(); $m->setDimension(320, 240); $i = $m->add($p); $i->moveTo(160, 120); for ($n=0; $n<=1.001; $n+=0.01) { $i->setRatio($n); $m->nextFrame(); } header('Content-type: application/x-shockwave-flash'); $m->output(); ?>`
