php实现批量压缩图片文件大小的脚本

while (false !== ($file = readdir($handle))) {
    if ($file == '.' || $file == '..') {
        continue;
    }
    write('d:/wamp/www/test/old/'.$file,'d:/wamp/www/test/new/'.$file);
}

closedir($handle);

}

function write($old,$new) {
$maxsize=1000;
$image = new Imagick($old);
if($image->getImageHeight() <= $image->getImageWidth())
{
$image->resizeImage($maxsize,Imagick::FILTER_LANCZOS,1);
}
else
{
$image->resizeImage(0,$maxsize,1);
}
$image->setImageCompression(Imagick::COMPRESSION_JPEG);
$image->setImageCompressionQuality(90);
$image->stripImage();
$image->writeImage($new);
$image->destroy();
}
?>
