Dealing with raw jpg data

[joeb]

Hi,

 

I have a flash app that I am developing for doing some photo manipulation.  One of the apps features is to save the updated image back to the server.  I am using a php script to do this.  The script currently gets given the raw jpeg data as a string, and the location for the file to be saved.  I am wondering if i can create an image object of some form from the raw data.

<?php

if ( isset ( $GLOBALS["HTTP_RAW_POST_DATA"] )) {

// get bytearray
$img = $GLOBALS["HTTP_RAW_POST_DATA"];

// add headers for download dialog-box
$fileName=$_GET['name'];
imagejpeg($img, $fileName, 90);

}  else echo 'An error occured.';

?>

 

Right now, the imagejpeg line does not work because it wants an image object and i am giving it a string of raw data.  Is there a simple way to turn the string of raw data into an actual object?

 

Thanks.

 

ps, $img contains the raw data, and $fileName contains the relative server path for the save.
