Code: Select all
$outputLocation = 'output.png';
$mask = new \Imagick('mask.png');
$overlay = new \Imagick('overlay.png');
$overlay->resizeImage(800, 600, \Imagick::FILTER_LANCZOS, 1);
$overlay->compositeImage($mask, \Imagick::COMPOSITE_COPYOPACITY, 0, 0, \Imagick::CHANNEL_ALPHA);
$overlay->writeImage($outputLocation );
$mask->destroy();
$overlay->destroy();
Does anyone have any idea how I can dramatically reduce the output size? As these images are intended for web and the input files are small, I was expecting around the 50KB-100KB mark or thereabouts.
Appreciate your time, thanks
Edit: I've added the output of `$imagick->identifyImage()` below each image and note that units become Pixels Per Centimeter when the input is "Undefined??" + "PPI". Not exactly sure what I'm looking at when I read 99% of it so hoping it helps with a solution
