tags.php (Raptor's answer)
<?php
include('../config.php');
$image = new Imagick();
$image->readImage("C:/xampp/htdocs/cmanager/uploads");
$image->setImageProperty('keywords', 'Imagick');
print($image->getImageProperty('keywords'));推荐答案
你需要 ImageMagick 的 setImageProperty() 有助于实现您的目标.
You need ImageMagick's setImageProperty() help to achieve your goal.
<?php
$image = new Imagick();
$image->newImage(300, 200, "black"); // or load your PNG into Imagick
$image->setImageProperty('keywords', 'Imagick');
echo $image->getImageProperty('keywords');
?>
需要 PHP 编译 ImageMagick 6.3.2+.
Require PHP to compile against ImageMagick 6.3.2+.
