There are two graphic files. First file - JPG background image

The second file is a PNG with a figure in the center with a black border around the contour.

Question: How to combine two files with transparency preservation? The background from the first file should be placed inside the shape on the second file (see an example).

Example

Images:

PNG file - profiles.in.ua/tmp/sample2.jpg

JPG file - profiles.in.ua/tmp/sample1.png

I try to do this:

     $ mask = new Imagick (realpath ('mask.png'));

     $ pattern = new Imagick (realpath ('pattern.jpg'));

     $ pattern-> resizeImage ($ mask-> width, $ mask-> height, Imagick :: FILTER_LANCZOS, 1);

     $ pattern-> compositeImage ($ mask, Imagick :: COMPOSITE_ATOP, 0, 0);

     header ("Content-Type: image / png");

     echo $ pattern-> getImageBlob ();

     $ mask-> destroy ();

     $ pattern-> destroy ();

Often this means that both questions are equally useless, although anything can happen .-. Here you can do more in the opposite direction, if I understand the mechanism correctly, but there is no reference to a duplicate to make sure. - D-side

I used something like this, maybe it will help you

$img_path = "img1.jpg"; //передаем скрипту изображение, на которое нужно что-то наложить, в формате .jpg $watermark = "watermark.png"; //тут хранится путь к накладываемому изображению, в формате .png $img = imagecreatefromjpeg($img_path); //создаем исходное изображение $water_img = imagecreatefrompng($watermark); //создаем водный знак $water_size = getimagesize($water_img); //узнаем размеры водного знака, чтобы правильно выполнить наложение imagecopy($img, $water_img, 0, 0, 0, 0, $water_size[0], $water_size[1]); //накладываем водный знак на изображение по заданным координатам. header("Content-type: image/jpeg"); imagejpeg($img, $water_img , 100);
