SWFBitmap

Loads Bitmap object ()
new swfbitmap ( string filename [, int alphafilename] )

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.

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.

Note:

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.

Example 550. Import PNG files

copy to clipboard
<?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.

Example 551. swfbitmap() example

copy to clipboard
<?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();
?>
