Read pdf metadata with purePDF | Alessandro Crugnola

In the recent purePDF update I’ve added the getInfo method to the PdfReader class, this allows to extract pdf informations once the document has been parsed.

Here’s an example:

var pdf: ByteArray = URLLoader( event.target ).data as ByteArray;
var reader: PdfReader = new PdfReader( pdf );
reader.addEventListener( Event.COMPLETE, onReadComplete );
reader.readPdf();

function onReadComplete(event:Event):void
{
	var map: HashMap = reader.getInfo();
	for( var iterator: Iterator = map.keySet().iterator(); iterator.hasNext(); )
	{
		var key: String = iterator.next();
		trace( key + ": " + map.getValue( key ) );
	}
}

In this way all the document’s metadata will be traced (Author, Creation Date, Title, Subject, etc..)

In order to extract the field directly simply use:

function onReadComplete(event:Event):void
{
	var map: HashMap = reader.getInfo();
	trace( "Author: " + map.getValue( "Author" ) );
	trace( "Creator: " + map.getValue( "Creator" ) );
	trace( "Title: " + map.getValue( "Title" ) );
}
