vb.org Archive - Scaling Images

Well, last night I made this image scaling script, and then forgot what it was for... and then it dawned on me - it could be used for fixing the problem with some fixed skins where images that are posted that are too big mess up the skin... So, here's the script:

PHP Code:


		
			
<?



// Scale Function



function scale($file) {



  // Set Globals



  $mw = 400; // Max Thumbnail Width

  $mh = 400; // Max Thumbnail Height



  // Get Initial Image Dimensions



  $image = getimagesize($file);

  $w = $image[0];

  $h = $image[1];



  // Calculate Thumbnail Dimensions



  if ($w > $mw or $h > $mh) {



    if ($w > $h) {



      $tw = $mw;

      $d = ($w / $mw);

      $th = ($h / $d);



    }



    else {



      $th = $mh;

      $d = ($h / $mh);

      $tw = ($w / $d);



    }



  }



  else {



    $tw = $w;

    $th = $h;



  }



  // Display Image



  echo"<img src=\"{$file}\" width=\"{$tw}\" height=\"{$th}\" border=\"0\">";



}



// Scale image.jpg



scale("image.jpg");



?>

I assume you could just stick that in the BBCode interperator somehow... The only problem I could think of would be that forums can have multiple skins, but I'm sure there's a way to fix that... I don't remember why I decided to post this, but... uhh...

Enjoy!

EDIT: Notice that I make alot of references to... "thumbnail" in the script. That's because it was originally a thumbnail script and then I sort of changed my mind about what it should do...
