PHP獲取圖片每個像素點

     $i = imagecreatefromjpeg("test.jpg"); //圖片路徑
        for ($x = 0; $x < imagesx($i); $x++) {
            for ($y = 0; $y < imagesy($i); $y++) {
                $rgb = imagecolorat($i, $x, $y);
                $r   = ($rgb >> 16) & 0xFF;
                $g   = ($rgb >> 8) & 0xFF;
                $b   = $rgb & 0xFF;
                echo "($r,$g,$b)";
//echo "$rgb ";
            }
            echo "\n";
