[Resolved] resizing image, and placing on background

[robtbs]

Hi, im having some problem placing an image on top of a black background...

the image just displays as black...

Heres my code so far...

//notes
/*
$size is generated using getimagesize()
and $ret is the ratio i want to resize to...

a maximum of 200 px wide
a maximum of 170 px high

$the_height is retrieved from $_GET['h']
$the_width is retrieved from $_GET['w']
$theimage is retrieved from $_GET['loc']
*/

//code
$final = imagecreatetruecolor($the_width, $the_height);
$thumb = imagecreatetruecolor($ret[0], $ret[1]);
$black = ImageColorAllocate($final, 0, 0, 0); 
imagefill($final, 0, 0, $black);
$image = imagecreatefromjpeg($theimage); 
@imagecopyresized($thumb, $image, 0, 0, 0, 0, $ret[0], $ret[1], $size[0], $size[1]);
$dest_x = $size[0] - $the_width / 2;
$dest_y = $size[1] - $the_height / 2;

//merge ontop of bg
imagecopy($final, $thumb, $dest_x , $dest_y, 0, 0, $ret[0], $ret[1]); 

imagejpeg($final,'',80); 
imagedestroy($image);
imagedestroy($thumb);
imagedestroy($final);

Many thanks in advanced

resolved it...
was my calculations the wrong way round 😉

for any one interested heres the final code.. i removed one of the image resources as it wasnt needed

$final = imagecreatetruecolor($the_width, $the_height);
$image = imagecreatefromjpeg($theimage); 

$x_dif = $the_width - $ret[0];
$y_dif = $the_height - $ret[1];

$x_dif = $x_dif / 2;
$y_dif = $y_dif / 2;

$dest_x = $x_dif;
$dest_y = $y_dif;

@imagecopyresized($final, $image, $dest_x, $dest_y, 0, 0, $ret[0], $ret[1], $size[0], $size[1]);

imagejpeg($final,'',80); 
imagedestroy($image);
imagedestroy($final);
