WHAT IS SWFMILL?

swfmill is a tool to process Shockwave Flash(TM) (SWF) files.
It can convert SWF from and to an XML-dialect called "swfml", 
which is closely modeled after the SWF file format.

It also provides a libxslt-based XSL transformator that
supports an extension ("swft") which helps with generating
IDs for SWF objects and can import an SWF as XML using an
XPath command (swft:document()).

As a simple application of such functionality, swfmill can
pack together a bunch of media files (jpeg and png images,
other SWF movies, TrueType fonts) into an SWF as "library 
objects" for your attachMovie() pleasure.


WARNING

swfmill is alpha-quality software. It might well not work
as it should. Please report your experiences if that seems
to be the case, send in (if possible small) SWFs or patches.


DEPENDENCIES

swfmill requires, and the windows binary release contains
code from:
	libxml2  - (C) 1998-2003 Daniel Veillard. 
	libxslt/exslt

COMPILING AND INSTALLING
	
on linux, use the "GNU-standard"
	./configure && make && make install

on windoze, if you have use for a tool like this,
you know better than me where to put swfmill.exe.
	
	
USAGE

see swfmill -h for general usage options.

convert an SWF (foo.swf) to XML:
	swfmill swf2xml foo.swf bar.xml
	
convert such XML to SWF:
	swfmill xml2swf bar.xml meep.swf


SIMPLE SWFML DIALECT

for library generation, and probably other fun swf
construction, swfmill supports a simplified XML
dialect. to create a library swf that includes some
assets, construct an XML file that looks like this:

<?xml version="1.0" encoding="iso-8859-1"?>
<movie width="320" height="240" framerate="12">
	<background color="#ffffff"/>

	<frame>
		<library>
			<clip id="jpg" import="library/testjpg.jpg"/>
			<clip id="png" import="library/testpng.png"/>
			<clip id="swf" import="library/shape.swf"/>
		</library>
	
		<font id="vera" import="library/vera.ttf"
			glyphs="abcdefghijklmnopqrstuvwxyz"/>
	</frame>
</movie>

and run swfmill:
	swfmill simple <the-xml-above.xml> output.swf
	
output.swf should now contain the specified assets (the jpg,
pngs, other swf and font) specified.

Some notes:
	* the file paths in the simple xml are relative to
	  where you start swfmill.
	* any <clip import=".."/> that is placed within a
	  <library/> tag will be exported for attachMovie
	  with linkage id == their id attribute. for the above
	  example, you can attach library/testjpg.jpg with:
		_root.attachMovie("jpg","foo",1);
	* the font is available by its id also, and will contain
	  only the characters specified in its glyph attribute.
	  make sure you specify the correct encoding in the
	  <?xml?> processing instruction for special characters.


SHARED LIBRARIES

swfmill supports both generation and use of shared libaries.
To generate a shared libary, simply put your assets in a 
<library/> tag just as for attachMovie (see above).

To use a shared library, the library swf has to be available
both locally and under its "public" URL. Assuming you have
put your library on http://foo.com/library.swf, and the swf
is also in the library/ subdirectory of where you run
swfmill, put this in your definition XML:
	<import file="library/library.swf" 
			url="http://foo.com/library.swf"/>
That should import all symbols that are exported in
library.swf, so they should be available under their name
with attachMovie(). Note: this only works with proper
assets, not with fonts. If you know how to use a font
from a shared library, please tell me.
