SWFBitmap::__construct

Loads Bitmap object

Description

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();
?>
