alivePDF, PurePDF and actionscript 3.0

Here's a super rudimentary example to generate a PDF using PurePDF:

// click anywhere
package {
    import flash.display.Sprite;
    import flash.events.Event;
    import flash.events.MouseEvent;
    import flash.net.FileReference;
    import flash.utils.ByteArray;
    
    import org.purepdf.elements.Paragraph;
    import org.purepdf.pdf.PageSize;
    import org.purepdf.pdf.PdfDocument;
    import org.purepdf.pdf.PdfWriter;
    import org.purepdf.pdf.fonts.BaseFont;
    import org.purepdf.pdf.fonts.FontsResourceFactory;
    import org.purepdf.resources.BuiltinFonts;
    
    public class PurePDFExample extends Sprite {
        public function PurePDFExample():void {
            stage.addEventListener(MouseEvent.CLICK, stageClick);
        }
        
        private function stageClick(e:MouseEvent):void {
            generatePDF();
        }
        
        private function generatePDF():void {
            FontsResourceFactory.getInstance().registerFont(BaseFont.HELVETICA, new BuiltinFonts.HELVETICA());
            var bytes:ByteArray = new ByteArray();
            var writer:PdfWriter = PdfWriter.create(bytes, PageSize.A4);
            var document:PdfDocument = writer.pdfDocument;
            document.open();
            document.add(new Paragraph("Hello World!"));
            document.close();
            new FileReference().save(bytes);
        }
    }
}
