swfbitmap() creates a new SWFBitmap object from
the Jpeg or DBL file named filename.
alphafilename indicates a MSK file to
be used as an alpha mask for a Jpeg image.
注:
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.
例子 1. Import PNG files
<?php
$s = new SWFShape();
$f = $s->addFill(new SWFBitmap("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.
例子 2. swfbitmap() example
<?php
$s = new SWFShape();
// .msk file generated with "gif2mask" utility
$f = $s->addFill(new SWFBitmap("alphafill.jpg", "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();
?>
