Hi!
I’m building an application that resizes clients logo to a certain width/height and also want to add a transparent background. I’m using iMagick and PHP. The following code does not create an image with a transparent background (just creates it on white). What do I need to change? This has been driving me mad.
$thumb = new Imagick($original);
$thumb->thumbnailImage($width,$height,true);
/* create canvas */
$canvas = new Imagick();
$canvas->newImage($width, $height, new ImagickPixel('transparent'), 'png');
$geometry = $thumb->getImageGeometry();
$x = ($width - $geometry['width']) / 2;
$y = ($height - $geometry['height']) / 2;
$canvas->compositeImage($thumb, imagick::COMPOSITE_OVER, $x, $y);
$canvas->writeImage($new_file);
$canvas->destroy();
Thanks in advance.
