Question

I have sent a base64 encoded string via AJAX to PHP and created an image resource with imagecreatefromstring – all is fine.

Now I want to get the base64 encoded string after resizing te image, but i CANT find a function to get the base64encoded string.

Taken from http://www.php.net/manual/en/book.image.php#93393

$image = imagecreatefromstring($file);

// start buffering
ob_start();
imagepng($image);
$contents =  ob_get_clean();

echo "<img src='data:image/png;base64,".base64_encode($contents)."' />";

imagedestroy($image);
