With the release of Flash Player 10, you can easily create an image file to display all the contents into an image on the fly. But with the help of 'Alive PDF' and Php, you can actually create PDF on the fly.
So let us take a look at some coding. :D
<?php
$method = $_GET['method'];
$name = $_GET['name'];
if ( isset ( $GLOBALS["HTTP_RAW_POST_DATA"] )) {
// get bytearray
$pdf = $GLOBALS["HTTP_RAW_POST_DATA"];
// add headers for download dialog-box
header('Content-Type: application/pdf');
header('Content-Length: '.strlen($pdf));
header('Content-disposition:'.$method.'; filename="'.$name.'"');
echo $pdf;
} else echo 'An error occured.';
?>The above Php script was taken from the Alive PDF website.The following would be the source file of my Main Application in Flex.
