<title>Introduction</title>
<simpara>
Ming is an open-source (LGPL) library which allows you to create SWF
("Flash") format movies. Ming supports almost all of Flash 4's features,
including: shapes, gradients, bitmaps (pngs and jpegs), morphs ("shape
tweens"), text, buttons, actions, sprites ("movie clips"), streaming mp3,
and color transforms--the only thing that's missing is sound events.
</simpara>
<simpara>
Ming is not an acronym.
</simpara>
<simpara>
Note that all values specifying length, distance, size, etc. are in "twips",
twenty units per pixel. That's pretty much arbitrary, though, since the player
scales the movie to whatever pixel size is specified in the embed/object tag,
or the entire frame if not embedded.
</simpara>
<simpara>
Ming offers a number of advantages over the existing PHP/libswf module.
You can use Ming anywhere you can compile the code, whereas libswf is
closed-source and only available for a few platforms, Windows not one of
them. Ming provides some insulation from the mundane details of the SWF
file format, wrapping the movie elements in PHP objects. Also, Ming is
still being maintained; if there's a feature that you want to see, just
let us know <ulink url="mailto:&email.ming;">&email.ming;</ulink>.
</simpara>
<simpara>
Ming was added in PHP 4.0.5.
</simpara>

<sect1 id="ming.install">
<title>Installation</title>
<para>
To use Ming with PHP, you first need to build and install the Ming
library. Source code and installation instructions are available at the
Ming home page : <ulink url="&url.ming;">&url.ming;</ulink>
along with examples, a small tutorial, and the latest news.
</para>
<para>
Download the ming archive. Unpack the archive. Go in the
Ming directory. make. make install.
</para>
<para>
This will build <filename>libming.so</filename> and install it
into <filename>/usr/lib/</filename>, and copy
<filename>ming.h</filename> into <filename>/usr/include/</filename>.
Edit the <literal>PREFIX=</literal> line in the
<filename>Makefile</filename> to change the installation directory.

uncompress it and copy it to your php modules directory.
(you can find your php module directory by running
<command>php-config --extension-dir</command>).
Now either just add <literal>extension=php_ming.so</literal>
to your <filename>php.ini</filename> file, or put
<literal>dl('php_ming.so');</literal> at the head of all of your
Ming scripts.

oddities (can skip over an initial ID3 tag, but that's about it).
Like <function>SWFShape->addJpegFill</function>, this isn't a stable function- we'll
probably need to make a separate SWFSound object to contain sound types.
</para>
<para>
Note that the movie isn't smart enough to put enough frames in to contain
the entire mp3 stream- you'll have to add (length of song * frames per second)
frames to get the entire stream in.

Yes, now you can use ming to put that rock and roll devil worship music

<para>
What this nonsense is about is, every edge segment borders at most two fills.
When rasterizing the object, it's pretty handy to know what those fills are
ahead of time, so the swf format requires these to be specified.
</para>
<para>
<function>swfshape->setleftfill</function> sets the fill on the left side of
the edge- that is, on the interior if you're defining the outline of the shape in a counter-clockwise
fashion. The fill object is an SWFFill object returned from one of the addFill
functions above.
</para>
<para>
This seems to be reversed when you're defining a shape in a morph, though.
If your browser crashes, just try setting the fill on the other side.

You can't import png images directly, though- have to use the png2dbl

The methods here are sort of weird. It would make more sense to just
have newSWFMorph(shape1, shape2);, but as things are now, shape2 needs
to know that it's the second part of a morph. (This, because it starts
writing its output as soon as it gets drawing commands- if it kept its
own description of its shapes and wrote on completion this and some
other things would be much easier.)

0 is all of the letters written at the same point. This doesn't really work
that well because it inflates the advance across the letter, doesn't add
the same amount of spacing between the letters. I should try and explain
that better, prolly. Or just fix the damn thing to do constant spacing.
This was really just a way to figure out how letter advances work,
anyway.. So nyah.

FDB ("font definition block") is a very simple wrapper for the SWF DefineFont2

SWT Generator template files with the included makefdb utility- look in the

<para>
Browser-defined fonts don't contain any information about the font other
than its name. It is assumed that the font definition will be provided by
the movie player. The fonts _serif, _sans, and _typewriter should always
be available. For example:
<programlisting role="php">
&lt;?php
$f = newSWFFont("_sans");

will give you the standard sans-serif font, probably the same as what you'd get
with <literal>&lt;font name="sans-serif"&gt;</literal> in HTML.

<function>swftextfield</function> creates a new text field object.

they can't be rotated, scaled non-proportionally, or skewed, but they can
be used as form entries, and they can use browser-defined fonts.

<function>swfaction</function> creates a new Action, and
compiles the given script into an SWFAction object.
</para>
<para>
The script syntax is based on the C language, but with a lot taken out- the SWF
bytecode machine is just too simpleminded to do a lot of things we might like.
For instance, we can't implement function calls without a tremendous
amount of hackery because the jump bytecode has a hardcoded offset
value. No pushing your calling address to the stack and returning-
every function would have to know exactly where to return to.

Additionally, the following commands may be used:
<variablelist>
<varlistentry>
<term>duplicateClip(clip, name, depth)</term>

and is at depth depth.
</simpara>
</listitem>
</varlistentry>
<varlistentry>
<term>removeClip(expr)</term>
<listitem>
<simpara>

</simpara>
</listitem>
</varlistentry>
<varlistentry>
<term>trace(expr)</term>
<listitem>
<simpara>

</simpara>
</listitem>
</varlistentry>
<varlistentry>
<term>startDrag(target, lock, [left, top, right, bottom])</term>
<listitem>
<simpara>

<varlistentry>
<term>stopDrag()</term>
<listitem>
<simpara>
Stop dragging my heart around. And this movie clip, too.
</simpara>

</listitem>
</varlistentry>
<varlistentry>
<term>getURL(url, target, [method])</term>
<listitem>
<simpara>
Load the given url into the named target. The target argument can be a
frame name (I think), or one of the magical values "_level0" (replaces
current movie) or "_level1" (loads new movie on top of current movie).
The optional method argument can be post or get if you want to submit
variables back to the server.
</simpara>
</listitem>
</varlistentry>
<varlistentry>
<term>loadMovie(url, target)</term>
<listitem>
<simpara>
Same as above, more or less. Come to think of it, I don't quite know what
the difference is.
</simpara>
</listitem>
</varlistentry>
<varlistentry>
<term>nextFrame()</term>
<listitem>
<simpara>
Go to the next frame.

<listitem>
<simpara>
Start playing the movie.

<varlistentry>
<term>stop()</term>
<listitem>

<simpara>
Stop playing all sounds.
</simpara>
</listitem>
</varlistentry>
<varlistentry>
<term>gotoFrame(num)</term>
<listitem>
<simpara>
Go to frame number num. Frame numbers start at 0.
</simpara>
</listitem>
</varlistentry>
<varlistentry>
<term>gotoFrame(name)</term>
<listitem>
<simpara>
Go to the frame named name. Which does a lot of good, since I
haven't added frame labels yet.
</simpara>
</listitem>
</varlistentry>
<varlistentry>
<term>setTarget(expr)</term>
<listitem>
<simpara>
Sets the context for action. Or so they say- I really have no
idea what this does.
</simpara>
</listitem>
</varlistentry>
</variablelist>
And there's one weird extra thing. The expression frameLoaded(num) can be used
in if statements and while loops to check if the given frame number has been
loaded yet. Well, it's supposed to, anyway, but I've never tested it and I
seriously doubt it actually works. You can just use /:framesLoaded instead.

So, setting a sprite's x position is as simple as <literal>/box.x = 100;</literal>.
Why the slash in front of the box, though? That's how flash keeps
track of the sprites in the movie, just like a unix filesystem-
here it shows that box is at the top level. If the sprite named
box had another sprite named biff inside of it, you'd set its x
position with /box/biff.x = 100;. At least, I think so; correct
me if I'm wrong here.

This simple example will handles keyboard actions.
(You'll probably have to click in the window to give it focus.
And you'll probably have to leave your mouse in the frame, too.
If you know how to give buttons focus programatically, feel free
to share, won't you?)
