demo for getImageHistogram about imagickdemos HOT 1 CLOSED

Sorry no. I just can't justify making demos for other people right now. You should be able to modify the code to do what you want. Just change it bit by bit until it does what you want.

btw i suspect you might actually want to still have the separate colours, even if they are on top of each other on the same histogram. That could be achieved with copying the individual color channels.

$canvas->compositeImage($redHistogram, \Imagick::COMPOSITE_COPYRED, 0, 0);
$canvas->compositeImage($greenHistogram, \Imagick::COMPOSITE_COPYGREEN, 0, 0);
$canvas->compositeImage($blueHistogram, \Imagick::COMPOSITE_COPYBLUE, 0, 0);
