PHP 给GIF 缩略图实例代码

请注意使用writeImages()而不是writeImage()

<?php
try
{
    // Read in the animated gif
    $animation = new Imagick("animation.gif");
    
    // Loop through the frames
    foreach ($animation as $frame)
    {
        // Thumbnail each frame
        $frame->thumbnailImage(100, 100);
        
        // Set virtual canvas size to 100x100
        $frame->setImagePage(100, 100, 0, 0);
    }
    
    // Write image to disk. Notice writeImages instead of writeImage
    $animation->writeImages("animation_thumbnail.gif");
    echo "Images written";
}
catch (Exception $e)
{
    echo $e->getMessage();
}
?>
