A versatile Swiss Army Knife for extraction and processing of IPTC, EXIF and other image metadata.

== Description ==

A must have tool for photographers who edit their images in **Lightroom** or **Photomechanic** and
don't want to waste their precious time by writing all the **keywords** and **categories**
once again by hand.

WordPress by default extracts the **EXIF ImageDescription** of an uploaded image to
the **Description** field and the **IPTC Headline** to the **Title** field of
the **Edit Media** form.

**Image Metadata Cruncher** gives you ultimate controll over this behaviour.
You decide what metadata gets where and in what form.


Moreover, the plugin's simple but powerfull templating system allows you to
convert the extracted metadata into complex strings like:

> Image was taken with Canon 7D, exposure was 1/125s and aperture was f/2.8.

You can even extract metadata to unlimited custom **post meta** that will be saved
with the image to the database.

The plugin also has some usefull public methods which you can use in your code:

This will return the complete metadata of the image in a stuctured array same as {ALL:PHP}.
	
	$metadata = $image_metadata_cruncher->get_meta_by_path( '/path/to/your/image.jpg' );
	
The same but by attachment post ID.
	
	$metadata = $image_metadata_cruncher->get_meta_by_id( $attachment_ID );
	
You can crunch an already uploaded attachment with the `crunch()` method.
The template and its indexes are optional. If missing, templates from plugin's settings will be used.
	
	$template = array(
		'title' => '{IPTC:Title}',
		'caption' => '{IPTC:Caption}',
		'description' => '{IPTC:Headline}',
		'alt' => '{IPTC:Caption}',
		'custom_meta' => array(
			'camera-make' => '{EXIF:Make}',
	 		'camera-model' => '{EXIF:Model}',
		),
	)
	
	$image_metadata_cruncher->crunch( $attachment_ID, $template )

= Is it possible to extract metadata from already uploaded images? =

You can use the plugin's methods like this:

This will return the complete metadata of the image in a stuctured array same as {ALL:PHP}.
	
	$metadata = $image_metadata_cruncher->get_meta_by_path( '/path/to/your/image.jpg' );
	
The same but by attachment post ID.
	
	$metadata = $image_metadata_cruncher->get_meta_by_id( $attachment_ID );
	
You can crunch an already uploaded attachment with the `crunch()` method:
Which will extract metadata from the attachment image file and
update the attachment post according to the optional template array.
Templates from plugin settings will be used for missing indexes.
	
	$template = array(
		'title' => '{IPTC:Title}',
		'caption' => '{IPTC:Caption}',
		'description' => '{IPTC:Headline}',
		'alt' => '{IPTC:Caption}',
		'custom_meta' => array(
			'camera-make' => '{EXIF:Make}',
	 		'camera-model' => '{EXIF:Model}',
		),
	)
	
	$image_metadata_cruncher->crunch( $attachment_ID, $template )
