imagecopyresized just copies

[Andy Pieters <mailings@xxxxxxxxxxxxxxxx>]

Hi all

I wanted to make a simple script to make a resized image from an uploaded one.

I used the example found on the php.net website


							   list($width,$height,$type)=getimagesize($newfile);
							   $newwidth=350;
							   $newheight=50;
							   $thumb=imagecreatetruecolor($newwidth,$newheight);
							   $thumbname=str_replace(".$filedetails[extension]",
													  "_thumb.$filedetails[extension]",$newfile);
							   $main=null;
							   switch($type)
							   {case 1: 	$main=imagecreatefromgif($newfile);	#gif
											break;
								case 2:		$main=imagecreatefromjpeg($newfile); #jpeg
											break;
								case 3:		$main=imagecreatefrompng($newfile); #png
											break;
							   }
							   if(!(is_null($main)))
							   {imagecopyresized($thumb,$main,0,0,0,0,$newwidth,$newheight,$width,
$height);
								switch($type)
								{case 1:	imagegif($main,$thumbname);
											break;
								 case 2:	imagejpeg($main,$thumbname);
											break;
								 case 3:	imagepng($main,$thumbname);
								 chmod($thumbname,0600); #read&write for apache only
								}
								imagedestroy($main);
								imagedestroy($thumb);

When I examine the two files, the are binary different but size and width are 
equal.

Anybody know why?

With kind regards


Andy
