Question

PHP Image resize returns only black background.

I read all similar posts here, but none of them fixed my problem.

Here is the code:

$namef = $_FILES['image']['name'];

$tmp_name = $_FILES['image']['tmp_name'];

$src = imagecreatefromjpeg($tmp_name);

$location = "../userpictures/standard/".$mdid.".".$mzad;

move_uploaded_file($tmp_name, $location);

list($width, $height, $type, $att) = getimagesize($location);

$newwidth = 200;
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);

imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,
 $width,$height);

$locations = "../userpictures/medium/".$mdid.".".$mzad;

imagejpeg($tmp,$locations,100);

move_uploaded_file($tmp_name, $location);

I’ve checked whether this code was valid on php tutorials and it was ok with the code.

Answer 1

You create your images with imagecreatetruecolor, which create a new image of W x H filled in black.

See http://php.net/manual/en/function.imagecreatetruecolor.php:

imagecreatetruecolor() returns an image identifier representing a black image of the specified size.
