README

Transformist is a PHP file conversion library. It provides a high level API to convert files into different formats painlessly.

It is also designed to be easily extended, just by adding custom converters.

Example

Here is what you could do to convert every word documents to PDF files in a directory:

<?php

$Transformist = new Transformist( );
$Transformist->setup(
	'/path/to/directory',
	'application/msword',
	'application/pdf'
);

if ( $Transformist->run( )) {
	// You're good to go !
}

?>

You can use the setup( ) method in different ways to convert multiple documents in one pass:

<?php

// Output directory

$Transformist->setup(
	array( '/path/to/input/directory' => '/path/to/output/directory' ),
	'application/msword',
	'application/pdf'
);


// Conversion of a particular file

$Transformist->setup(
	'/path/to/directory',
	'file.doc',
	'application/pdf'
);


// All files matching a pattern

$Transformist->setup(
	'/path/to/directory',
	'*.doc',
	'application/pdf'
);


// Multiple conversions

$Transformist->setup(
	'/path/to/directory',
	array(
		'*.doc'     => 'application/pdf',
		'image/jpg' => 'image/png'
	)
);

?>

Available conversions

Before going any further, you may want to know about the conversions that Transformist can handle. There's a method for that:

<?php

$conversions = $Transformist->availableConversions( );

?>

This method returns an array of all possible conversions. Each of its key represents an input type, and points to an array of output types.

Typically, it looks like this:

<?php

array(
	'image/jpeg' => array(
		'image/png'
	),
	'image/png' => array(
		'image/tiff'
	)
);

?>

Here you can convert JPG images to PNG, and PNG images to TIFF.

Test

Transformist provides a way to check all converters for validity. Some could be runnable without further configuration, while others could rely on external librairies that must be installed for the converter to work.

<?php

$results = $Transformist->testConverters( );

// Or statically:

$results = Transformist::testConverters( );

?>

$results now looks like this:

<?php

array(
	'Transformist_Converter_Office_Pdf' => true,
	'Transformist_Converter_Office_Png' => 'An external library is missing!',
	'Transformist_Converter_Office_Tiff' => true
);

?>

You should run this function only once when configuring your system or troubleshooting errors, as some converters could do some heavy computation to test their environment.
