Description

new swfbitmap (string filename [, int alphafilename])

Waarschuwing

Deze functie is EXPERIMENTEEL. Dat betekent, dat het gedrag van deze functie, deze functienaam, in concreto ALLES dat hier gedocumenteerd is in een toekomstige uitgave van PHP ZONDER WAARSCHUWING kan veranderen. Wees gewaarschuwd, en gebruik deze functie op eigen risico.

swfbitmap() creates a new SWFBitmap object from the Jpeg or DBL file named filename. alphafilename indicates a MSK file to be used as an alpha mask for a Jpeg image.

Opmerking: We can only deal with baseline (frame 0) jpegs, no baseline optimized or progressive scan jpegs!

SWFBitmap has the following methods : swfbitmap->getwidth() and swfbitmap->getheight().

You can't import png images directly, though- have to use the png2dbl utility to make a dbl ("define bits lossless") file from the png. The reason for this is that I don't want a dependency on the png library in ming- autoconf should solve this, but that's not set up yet.

Voorbeeld 1. Import PNG files


<?php
  $s = new SWFShape();
  $f = $s->addFill(new SWFBitmap("png.dbl"));
  $s->setRightFill($f);

  $s->drawLine(32, 0);
  $s->drawLine(0, 32);
  $s->drawLine(-32, 0);
  $s->drawLine(0, -32);

  $m = new SWFMovie();
  $m->setDimension(32, 32);
  $m->add($s);

  header('Content-type: application/x-shockwave-flash');
  $m->output();
?>
      

And you can put an alpha mask on a jpeg fill.

Voorbeeld 2. swfbitmap() example


<?php

  $s = new SWFShape();

  // .msk file generated with "gif2mask" utility
  $f = $s->addFill(new SWFBitmap("alphafill.jpg", "alphafill.msk"));
  $s->setRightFill($f);

  $s->drawLine(640, 0);
  $s->drawLine(0, 480);
  $s->drawLine(-640, 0);
  $s->drawLine(0, -480);

  $c = new SWFShape();
  $c->setRightFill($c->addFill(0x99, 0x99, 0x99));
  $c->drawLine(40, 0);
  $c->drawLine(0, 40);
  $c->drawLine(-40, 0);
  $c->drawLine(0, -40);

  $m = new SWFMovie();
  $m->setDimension(640, 480);
  $m->setBackground(0xcc, 0xcc, 0xcc);

  // draw checkerboard background
  for($y=0; $y<480; $y+=40)
  {
    for($x=0; $x<640; $x+=80)
    {
      $i = $m->add($c);
      $i->moveTo($x, $y);
    }

    $y+=40;

    for($x=40; $x<640; $x+=80)
    {
      $i = $m->add($c);
      $i->moveTo($x, $y);
    }
  }

  $m->add($s);

  header('Content-type: application/x-shockwave-flash');
  $m->output();
?>
