Resize slike iz jedne u drugu promenljivu

^{26.07.2011. u 01:59 - pre 155 meseci}

Znaci imam jednu promenljivu koja je ustvari slika

ja mislim da se to kreira ovako

$img = imagecreatefromjpeg( $srcFile );

e sad hteo bih da tu sliku resizujem da joj sirina bude 550npr ali da se odnos strana ne izgubi tj da ostane isti.
Posle toga dobijenu sliku treba ponovo upisati u neku promenljivu da bi ostatak koda mogao da odradi ubacivanje texta i ostalo.
Pravim sajt za pravljenje demotivacija-vukajlija postera.

Nasao sam neki kod od nekih rusa - radi sve ali ne radi resize pa sam hteo da pomocu datalife engine-a i tog koda napravim ceo sajt koji ce slagati te postere i gde ce korisnici moci da ih generisu i postavljaju

evo ga kod (znaci radi sve samo ne smanjuje slike ako su ogromne)

Code:
<?php

  if (!defined("DATALIFEENGINE"))
  {
    die("Hacking Attemp!");
  }

    function win_to_utf($s)
{
for($i=0, $m=strlen($s); $i<$m; $i++)
{
$c=ord($s[$i]);
if ($c<=127)
{$t.=chr($c); continue; }
if ($c>=192 && $c<=207)
{$t.=chr(208).chr($c-48); continue; }
if ($c>=208 && $c<=239)
{$t.=chr(208).chr($c-48); continue; }
if ($c>=240 && $c<=255)
{$t.=chr(209).chr($c-112); continue; }
if ($c==184) { $t.=chr(209).chr(209);
continue; };
if ($c==168) { $t.=chr(208).chr(129);
continue; };
}
return $t;

    echo "picture file not found\n";
    exit;
  }
  $img = imagecreatefromjpeg( $srcFile );
  list($w, $h) = getimagesize( $srcFile );

  $ha1 = imagettfbbox($headerSize, 0, $font1, $header );

    $tpl->compile('content');
    $tpl->clear();
?>

malo ima nekih hijeroglifa ali to je zbog ruske cirilice.

Ako neko moze da pomogna... Hvala :)
