Read pdf metadata with purePDF

Alessandro Crugnola actionscript, purePDF , , , , ,
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" ) );
}
