PHP Manual: SWFDisplayItem->setRatio

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);
