//create a new Imagick object $image = new Imagick('image.jpg'); //set the alpha channel to 100 $image->setImageAlphaChannel(Imagick::ALPHACHANNEL_SET, 100); //save the modified image $image->writeImage('modified_image.jpg');In this example, we set the alpha channel value to 100, which will make the image slightly transparent. The php Imagick library is an object-oriented wrapper for the ImageMagick library. It provides a set of methods for image manipulation and processing.
