SWFBitmap->__construct()

(PHP 5)

SWFBitmap->__construct() — Loads Bitmap object

Description

SWFBitmap

SWFBitmap __construct ( mixed $file [, mixed $alphafile ] )

Warning

This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk.

Creates the new SWFBitmap object from the given file .

Parameters

For both parameters you can provide a file pointer returned by fopen() or the image data, as a binary string.

file

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

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.

alphafile

An MSK file to be used as an alpha mask for a JPEG image.

Examples

Example #1 Importing a DBL file


<?php

$s = new SWFShape();

$f = $s->addFill(new SWFBitmap(file_get_contents("image.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();

?>

Example #2 Using an alpha mask


<?php



$s = new SWFShape();



// .msk file generated with "gif2mask" utility

$f = $s->addFill(new SWFBitmap(file_get_contents("alphafill.jpg"), file_get_contents("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();

?>
