SWFBitmap::__construct

(PHP 5 <= 5.3.0, PECL ming SVN)

SWFBitmap::__construct — Loads Bitmap object

Beschreibung

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

Warnung

Diese Funktion ist EXPERIMENTELL. Das Verhalten, der Funktionsname und alles Andere, was hier dokumentiert ist, kann sich in zukünftigen PHP-Versionen ohne Ankündigung ändern. Seien Sie gewarnt und verwenden Sie diese Funktion auf eigenes Risiko.

Creates the new SWFBitmap object from the given file.

Parameter-Liste

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

file

Hinweis:
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.

Beispiele

Beispiel #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();
?>

Beispiel #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();
?>
