Use PHP and Imagick to achieve image fusion effects

As a powerful image processing library, Imagick can implement various image operations in PHP, including image fusion effects. In this article, we will learn how to use PHP and Imagick to achieve image blending effects, along with code examples.

First, we need to ensure that the Imagick library has been installed correctly and related extensions enabled. You can look for the following two lines of code in PHP's configuration file. If not found, uncomment them and restart the web server.

;extension=imagick.so
;extension=imagick.dll

Next, we will create a simple PHP script to achieve the image blending effect. First, we need to load the two images to be fused. Image files can be loaded using Imagick's readImage method.

$mainImage = new Imagick('main_image.jpg');
$overlayImage = new Imagick('overlay_image.png');

Next, we need to make sure that both images are the same size so that they align when blending. Image size can be scaled using Imagick's scaleImage method.

$mainImage->scaleImage($overlayImage->getImageWidth(), $overlayImage->getImageHeight());

Then, we can use Imagick’s compositeImage method to fuse the two images. When blending, we can specify a blending mode, such as Imagick::COMPOSITE_BLEND, and the blending transparency.

$mainImage->compositeImage($overlayImage, Imagick::COMPOSITE_BLEND, 0, 0, Imagick::CHANNEL_ALPHA);

Finally, we can save the fused image to disk.

$mainImage->writeImage('result_image.jpg');

The complete code example is as follows:

$mainImage = new Imagick('main_image.jpg');
$overlayImage = new Imagick('overlay_image.png');

$mainImage->scaleImage($overlayImage->getImageWidth(), $overlayImage->getImageHeight());

$mainImage->compositeImage($overlayImage, Imagick::COMPOSITE_BLEND, 0, 0, Imagick::CHANNEL_ALPHA);

$mainImage->writeImage('result_image.jpg');

In the above code, we assume that there is already a main image named main_image.jpg and an image named ## Overlay image of #overlay_image.png. The program will fuse the two images and save the result as result_image.jpg.
