This is how to Monochrome a jpg [on Windows].. since I couldn't find it anywhere else.





<?php


header("Content-type: image/jpeg");





$IMagick = new IMagick('c:\\testing\\fruit.jpg');


$IMagick->setImageColorSpace(Imagick::COLORSPACE_GRAY);





echo $IMagick;


?>

If your getting strange/bad color rendering from a PDF, after trying the colorspace constants noted by jdstraughan, try other values outside that range.



In one case for me only $image->setImageColorSpace(22) provided useful color. I have found posts elsewhere using values up to 255.
