This method has to be called BEFORE any files are loaded into the Imagick object.

By default, Imagick will incorrectly read CMYK PDFs - it will read each channel as a greyscale page resulting in 4 times the number of pages. By specifying the desired colorspace (usually SRGB) before reading the file, GhostScript will automatically convert it.

= new Imagick();

// set the sampling resolution

// set the desired format

Right now this function doesn't appear to do anything, ref:

As mentioned in the answer, modulateImage works fine as a replacement for converting to gray scale.


= new Imagick("input.jpg");

$image->modulateImage(100, 0, 100);
