Im trying to create a rectangle with a tranparent fill in PHP, as I want to be able to eventually change the shape with $_GET, however I cannot get it to work with static values at the moment. All I seem to get is a big black rectangle.

I abandoned my code, as it appeared someone else has been trying this as well at the php website, but still I cant get it to work :-(

What Im tring to do it make something similar to:-
Rounded Rectangle
What I get is:-
Test image
My Code Im trying to get working is:-
<?php

function draw_roundrectangle($img, $x1, $y1, $x2, $y2, $radius, $color,$filled=1) {
    if ($filled==1){
        imagefilledrectangle($img, $x1+$radius, $y1, $x2-$radius, $y2, $color);
        imagefilledrectangle($img, $x1, $y1+$radius, $x1+$radius-1, $y2-$radius, $color);
        imagefilledrectangle($img, $x2-$radius+1, $y1+$radius, $x2, $y2-$radius, $color);

        imagefilledarc($img,$x1+$radius, $y1+$radius, $radius*2, $radius*2, 180 , 270, $color, IMG_ARC_PIE);
        imagefilledarc($img,$x2-$radius, $y1+$radius, $radius*2, $radius*2, 270 , 360, $color, IMG_ARC_PIE);
        imagefilledarc($img,$x1+$radius, $y2-$radius, $radius*2, $radius*2, 90 , 180, $color, IMG_ARC_PIE);
        imagefilledarc($img,$x2-$radius, $y2-$radius, $radius*2, $radius*2, 360 , 90, $color, IMG_ARC_PIE);
    }else{
        imageline($img, $x1+$radius, $y1, $x2-$radius, $y1, $color);
        imageline($img, $x1+$radius, $y2, $x2-$radius, $y2, $color);
        imageline($img, $x1, $y1+$radius, $x1, $y2-$radius, $color);
        imageline($img, $x2, $y1+$radius, $x2, $y2-$radius, $color);

        imagearc($img,$x1+$radius, $y1+$radius, $radius*2, $radius*2, 180 , 270, $color);
        imagearc($img,$x2-$radius, $y1+$radius, $radius*2, $radius*2, 270 , 360, $color);
        imagearc($img,$x1+$radius, $y2-$radius, $radius*2, $radius*2, 90 , 180, $color);
        imagearc($img,$x2-$radius, $y2-$radius, $radius*2, $radius*2, 360 , 90, $color);
    }                
}

$canvas = imagecreatetruecolor(200, 200);
draw_roundrectangle($canvas,10,10,40,40,50,$black);

header('Content-Type: image/jpeg');
imagejpeg($canvas);
imagedestroy($canvas);

?>

Any ideas?
