Reproduce code:
---------------
$file = '/path/to/Screenshot.png';
$path = '/var/www/html/images/temp.png';
$type = mime_content_type($file);
$i = imagecreatefrompng($file);
list($width, $height) = getimagesize($file);
if ($width > $height) $scale = $width / 260;
else $scale = $height / 240;
$imgWidth = round($width/$scale, 0);
$imgHeight = round($height/$scale, 0);
$newI = imagecreatetruecolor($imgWidth, $imgHeight);
$bgColor = imagecolorallocate($newI, 51, 85, 204);
imagefilledrectangle($newI, 0, 0, $imgWidth, $imgHeight, $bgColor);
imagecopyresampled($newI, $i, 0, 0, 0, 0, $imgWidth, $imgHeight, $width,
$height);
if ($type == 'image/jpeg') imagejpeg($finalImg, $path, 70);
else if ($type == 'image/x-png' || $type == 'image/png')
imagepng($finalImg, $path, 70);
header('Content-type: image/png');
imagepng($path);
Expected result:
----------------
prints the newly resized and created image to the screen
Actual result:
--------------
error: Allowed memory size of 8388608 bytes exhausted (tried to allocate
5242880 bytes) in /var/www/html/tmp/png-img.php on line 5
