GD and dynamic coloring

[andyd34]

I am trying to create an image, well I have created the image and am now trying to color it but its not working. here is the image page.

 

$image = imagecreatetruecolor(20, 20);

$back = imagecolorallocate($image, 255,  255,  255);
$fore = imagecolorallocate($image, 77, 77, 77);

// Draw the polygon

imagefilledrectangle($image, 0, 0, 20, 20, $back);

imagefilledpolygon($image, array (20, 20, 20, 0, 0, 0), 3, $fore);

// Output the picture to the browser
header('Content-type: image/png');

imagepng($image);
imagedestroy($image);

 

and here is how I am calling the image

 

<img src="styles/images/start_end.php" />

 

 

is there a way i can dynamically change the image foreground & background colors???

[teamatomic]

<img src="styles/images/start_end.php?fr=255&fg=255&fb=0&br=0&bg=0&bb=0" />

$fr=$_GET['fr'];

....

 

$back = imagecolorallocate($image, $fr,  $fg,  $fb);

$fore = imagecolorallocate($image, $br, $bg, $bb);
