Hi, currently i'm trying to use imagick to generate some images without saving them on the server and then outputting to the browser, my method of choice was image magic with the imagick extension for php. I read the documentation, and i'm sure the package is installed on my machine (windows xp, with xampp). the class is installed

imagick module  enabled

this is from the phpinfo so i know i have it installed, the thing is when i try to generate an image and save it, it works flawlessly, but when i try to output the image directly, i get the script url as an image

  $draw = new ImagickDraw();

    $draw->setFont('AnkeCalligraph.TTF');
    $draw->setFontSize(52);

    $draw->annotation(110, 110, "Hello World!");
    $draw->annotation(50, 220, "Hello World!");
    $canvas = new Imagick('./pictures/test_live.PNG');
    $canvas->drawImage($draw);
    $canvas->setImageFormat('png');
    header("Content-Type: image/png");
    echo $canvas;

this is the code used. if i use writeimage, then the file on the server is created with no problems. does anyone have any ideas what i'm doing wrong ?
