PPT Picture Transparency Add transparency gradient effect to PHP picture

Copy the Code code as follows:

$STRIMGSRC = file_get_contents ("http://127.0.0.1/5307754.jpg");
$IMGSRC = imagecreatefromstring ($STRIMGSRC);
$IMGSRC = Imagecreatefromjpeg ("5307754.jpg");
$IMGSRCW = Imagesx ($IMGSRC);
$imgsrch = Imagesy ($IMGSRC);
$width = 30;
$x 1 = 2;
$x 2 = $IMGSRCW-$x 1-20;
$y 1 = ($imgsrch-$width)-2;
$y 2 = $y 1 + $width;
$steps = $x 2-$x 1;
for ($i = 0; $i < $steps; $i + +)
{
$alphax = Round ($i/($steps/127)) +60;
if ($alphax >= 128)
$alphax = 127;
$alpha = Imagecolorallocatealpha ($imgsrc, 255, 255, 255, $alphax);
Imagefilledrectangle ($IMGSRC, ($i + $x 1), $y 1, ($i + $x), $y 2, $alpha);
}
Header (' Content-type:image/jpeg ');
Imagejpeg ($IMGSRC);
Imagedestroy ($IMGSRC);
?>
