The Imagick Function lets you create and change images using the ImageMagick
API. ImageMagick is a software suite that helps you make, edit, and modify
bitmap images. It reads, writes, and converts images in many formats like DPX,
EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF.
Requirements: You need PHP 5.1.3 and ImageMagick 6.2.4 to install
ImageMagick.
Here is an example of how to use the Imagick::brightnessContrastImage()
function in PHP.
<?php
// require_once('path/vendor/autoload.php');
// Create a new Imagick Object
$image = new Imagick(
'https://Your_Image_URL.png');
// brightnessContrastImage Function
$image->brightnessContrastImage(12, 30);
header('Content-type: image/png');
// Display the output image
echo $image;
?>
Replace "https://Your_Image_URL.png" with the image URL you want to
adjust the brightness and contrast.
This PHP code shows how to adjust the brightness and contrast of an image using the Imagick library.
