Image creation script problem

[audiopro]

This is part of a image creation script.
All the vars appear to be making the right noises but it does not produce any output.
Is the syntax of the reference to $culler[$i] correct?

for($i=0;$i<100;$i++){
	$rgb = ImageColorAt($im, 1, $i); 
	$r[$i] = ($rgb >> 16) & 0xFF; 
	$g[$i] = ($rgb >> 8) & 0xFF; 
	$b[$i] = $rgb & 0xFF; 
	$culler[$i] = imagecolorallocate ($newim,$r[$i],$g[$i],$b[$i]);
	imageline($newim,0,$i,$width,$i,[red]\$culler[$i][/red]);
}
header ("Content-type: image/jpeg");
imagejpeg($newim);

I have had to work round it by dropping the culler array altogether. I need the array later in the script but I will have to re-create it.

$culler = imagecolorallocate ($newim,200,200,200);
for($i=0;$i<100;$i++){
	$rgb = ImageColorAt($im, 1, $i); 
	$r[$i] = ($rgb >> 16) & 0xFF; 
	$g[$i] = ($rgb >> 8) & 0xFF; 
	$b[$i] = $rgb & 0xFF; 
	[red]$culler[/red] = imagecolorallocate ($newim,$r[$i],$g[$i],$b[$i]);
	imageline($newim,0,$i,$width,$i,$culler);
}
header ("Content-type: image/jpeg");
imagejpeg($newim);

Try:

$culler = imagecolorallocate ($newim,200,200,200);
for($i=0;$i<100;$i++){
    $rgb = ImageColorAt($im, 1, $i); 
    $r[$i] = ($rgb >> 16) & 0xFF; 
    $g[$i] = ($rgb >> 8) & 0xFF; 
    $b[$i] = $rgb & 0xFF; 
    $culler = imagecolorallocate ($newim,$r[$i],$g[$i],$b[$i]);
    imageline($newim,0,$i,$width,$i,$culler);
    $cullerarray[$i] = $culler ; // save the culler here.
}
header ("Content-type: image/jpeg");
imagejpeg($newim);
