gwax's rumblings

As I just recently suggested I might do, I have made a script for automatically generating color cycling animations of arbitrary sizes and speeds.

The script can be used at: http://blog.gwax.com/files/rgbanim.php

The script accepts the parameters height, width, and delay, so it can also be used in more interesting ways. Feel free to play around (if you crash it, let me know).

Ex.: http://blog.gwax.com/files/rgbanim.php?width=100&height=100&delay=7

Or, better still:

 - Width
 - Height
 - Delay

For the curious amongst you, the relatively simple code follows:

< ?php
if(isset($_GET['delay']) && is_numeric($_GET['delay']))
	$delay = max((int)$_GET['delay'], 1);
else
	$delay = 10;
 
if(isset($_GET['width']) && is_numeric($_GET['width']))
	$width = max(min((int)$_GET['width'], 1920), 1);
else
	$width = 320;
 
if(isset($_GET['height']) && is_numeric($_GET['height']))
	$height = max(min((int)$_GET['height'], 1080), 1);
else
	$height = 240;
 
$out = new Imagick();
$out->newImage($width, $height, '#FF0000', 'gif');
$out->setImageDelay($delay);
$out->newImage($width, $height, '#00FF00', 'gif');
$out->setImageDelay($delay);
$out->newImage($width, $height, '#0000FF', 'gif');
$out->setImageDelay($delay);
 
header('Content-type: image/gif');
echo $out->getImagesBlob();
?>
