# 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, 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.

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();
?>`
