When modifying the saturation of an image, we are doing it with CSS (saturate) with a value between 0 and 1. However, when passing it to Imagick with the command
$img->modulateImage(100,$saturation,100);
the results are not the same. We have multiplied the saturation value by 100, but the results are still not the same as what was applied in CSS.
Does anyone know the equivalence of saturation in CSS to that used by Imagick?
We need to clone the effect of css saturate() to PHP Imagick modulateImage(100,XX,100)
