SWFBitmap->__construct() -- Loads Bitmap object

Description

class SWFBitmap {

SWFBitmap __construct ( mixed file [, mixed alphafile] )

}

Avertissement

Cette fonction est EXPERIMENTALE. Cela signifie que le comportement de cette fonction, son nom et, concrètement, TOUT ce qui est documenté ici peut changer dans un futur proche, SANS PREAVIS ! Soyez-en conscient, et utilisez cette fonction à vos risques et périls.

Creates the new SWFBitmap object from the given file.

Liste de paramètres

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.

Exemples

Exemple 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();
?>

Exemple 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();
?>
