help on image header

i have a web service and accessing it is done thru query string. how
to access a certain header field using php? the sample program i saw
was done in java and it goes like this:

String shortcutcode = connection.getHeaderField("ShortCut");
ByteArrayInputStream bis = new ByteArrayInputStream (imageBytes,
0,imageBytes.length);
BufferedImage bim = ImageIO.read(bis);
bim = bim.getSubimage(0,0,bim.getWidth(),bim.getHeight()-12);


how to do the same in php?

 

please provide more details .. i dont seem to understand what you exactly mean..

 

actually i was able to get the desired string from the returned header by this way:

$ch = curl_init();
$timeout = 0;
curl_setopt ($ch, CURLOPT_URL, $xmyurl);
curl_setopt($ch, CURLOPT_HEADER, 1);

ob_start();
curl_exec($ch);
$s=ob_get_contents();
ob_end_clean();

at the same time this webservice returns also a binary bytecode to generate the image...i tried to continue the code this way but it doesnt return the complete image:

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
$image = curl_exec($ch);
curl_close($ch);

$n=strpos($s,'ShortCut:')+9;
$code = substr($s,$n,8);

header('Content-type: image/png');
$xim=@imagecreatefromstring($image);

$xbase = @imagecreatetruecolor(130,168);
$xback=imagecolorallocate($xbase, 255,255,255); //green
imagefill($xbase,0,0,$xback);

$xhead=@imagecreatefrompng('x.png');
imagecopy($xbase,$xhead,10,0,0,0,108,28);
imagecopy($xbase,$xim,0, 28, 0, 0, 130,140);
imagepng($xbase);

 

hmmmm ...interesting piece of code.. could you show me the output this file for a header ?

 

actually its quite confidential...due to company privacy. anyhow i will describe it to you, its fairly simple. all i wanted to is this:

1. from that webservice get a certain set of strings from the header
2. next, generate the image.

and these 2 steps will be done at the same time.

to get the header value:
$ch = curl_init();
$timeout = 0;
curl_setopt ($ch, CURLOPT_URL, $xmyurl);
curl_setopt($ch, CURLOPT_HEADER, 1);

ob_start();
curl_exec($ch);
$s=ob_get_contents();

now from the same url i want also to generate the image on the file. if just to create the image:

$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);

now...how to combine both functions?

 

i'm not pretty sure with this either .doesn't "imagecreatefromstring" create the needed image ?
