This function can be used to desaturate an image, i.e. to convert a coloured image into a greyscale:


= new Imagick ("image.jpg");
$im->setImageType (2);
//is now in 256 shades of grey

The cleaner way to set the type to grayscale is to use the Imagick class constant.

$oBw = new \Imagick($sSourceImage);

I've found this to be a rather harsh 'convert to grayscale' approach. Fred's color2gray script works much better, but it's written in Bash. Time to get it ported over lol
