<function>swfbitmap</function> creates a new SWFBitmap object from
the Jpeg or DBL file in <parameter>file</parameter>.
<parameter>alphafile</parameter> is a MSK file to
be used as an alpha mask for a Jpeg image.
Both parameters can be <function>fopen</function> resources or binary
strings.
</para>
<note>
<para>
We can only deal with baseline (frame 0) jpegs, no baseline optimized or
progressive scan jpegs!

</note>
<simpara>
SWFBitmap has the following methods : <function>swfbitmap->getwidth</function>
and <function>swfbitmap->getheight</function>.
</simpara>
<para>
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>
<title>Import PNG files</title>
<programlisting role="php">
<![CDATA[
<?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();
?>
]]>
</programlisting>

And you can put an alpha mask on a jpeg fill.
<example>
<title><function>swfbitmap</function> example</title>
<programlisting role="php">
<![CDATA[
<?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
