help in gd image manipulation

[cityboy101]

i have this situation:

ch = curl_init();

$timeout = 0;

curl_setopt ($ch, CURLOPT_URL, $xmyurl);

curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

// Getting binary data

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);

$image = curl_exec($ch);

curl_close($ch);

 

and display the output this way:

header("Content-type: image/png");

echo $image;

 

now what i want to do is edit $image as png file using gd. i tried it:

header('Content-type: image/png');

$xbase = @imagecreatetruecolor(130,168);

$xback=imagecolorallocate($xbase, 39,138,; //green

imagefill($xbase,0,0,$xback);

imagecopy($xbase,$image,0, 28, 0, 0, 130,140);

imagepng($xbase);

 

what supposed to happen is $image should be inside $xbase frame. however it doesnt work, instead only $xbase is showing. what to do with this?
