SWFBitmap
(PHP 4 >= 4.0.5)
SWFBitmap -- Loads Bitmap object
Description
SWFBitmap
swfbitmap ( 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. |
swfbitmap() creates a new SWFBitmap object from
the Jpeg or DBL file in file.
alphafile is a MSK file to
be used as an alpha mask for a Jpeg image.
Both parameters can be fopen() resources or binary
strings.
Note:
We can only deal with baseline (frame 0) jpegs, no baseline optimized or
progressive scan jpegs!
SWFBitmap has the following methods : swfbitmap->getwidth()
and swfbitmap->getheight().
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.
Example 1. Import PNG files
<?php
$s = new SWFShape();
$f = $s->addFill(new SWFBitmap(file_get_contents("png.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();
?>

And you can put an alpha mask on a jpeg fill.
Example 2. swfbitmap() example
<?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();
?>
