Good 'n Fast thumbnail script?!

marxx · 09-30-2007, 06:35 AM

Hello all!

Does anyone know good and fast thumbnail script?
I have trying many thumbnail functions and scripts and none of them are:
- fast enough
- Doesn't do what it should
- Is too complicated

Perfect script for me would be:
- What rename files
- Support for .gif .jpeg .png .bmp
- easy to use.. Function would be the best!

Before you post "Do it yourself" .. Well, I have try many times, but my skills just aren't that good! (yet) :(
I would use this in site where member is uploading picture, script is generating 3 versions of it. Small thumbnail (80x80), preview thumbnail (150x150) and view image (640x480) and uploading those own folder.

Thanks for all help - Marxx

I use the following function, but I wrote it almost a year ago now so it may not be the best way of doing it. You've got to remember though that manipulating images is an intensive task in itself.

PHP Code:


			
function doResize($szSource, $szDestination, $szExtension, $iResizeWidth, $iResizeHeight)
{
    declare(ticks = 1)
    {
        $szExtension = strtolower($szExtension);
        
         switch($szExtension)
         {
             case('jpg'):     $pSource = imagecreatefromjpeg($szSource); break;
             case('jpeg'):     $pSource = imagecreatefromjpeg($szSource); break;
             case('gif'):     $pSource = imagecreatefromgif($szSource); break;
             case('wbmp'):     $pSource = imagecreatefromwbmp($szSource); break;
             case('png'):     $pSource = imagecreatefrompng($szSource); break;
         }
         
         $pResized = imagecreatetruecolor($iResizeWidth, $iResizeHeight);
         list($iWidth, $iHeight) = getimagesize($szSource);
        
         if(!imagecopyresampled($pResized, $pSource, 0, 0, 0, 0, $iResizeWidth, $iResizeHeight, $iWidth, $iHeight))
         {
             return false;    
         }

        switch($szExtension)
        {
             case('jpg'):     $pResult = imagejpeg($pResized, $szDestination, 100); break;
             case('jpeg'):     $pResult = imagejpeg($pResized, $szDestination, 100); break;
             case('gif'):     $pResult = imagegif($pResized, $szDestination); break;
             case('wbmp'):     $pResult = imagewbmp($pResized, $szDestination); break;
             case('png'):     $pResult = imagepng($pResized, $szDestination); break;
         }
         
        if($pResult)
        {
            return true;
        }
            
        return false;
    }
}

Does anyone have a newer script that works like this?
Or is this script still up to date? :)

Resizing has never really been a fast task. Very server intensive. I'd say that's the best you're going to get because although the code may be a little out-dated, the process remains the best way to do it:

Load the original image into a new resource
Extract the original image's height and width
Create a blank canvas
Resize the original image and place it into the new canvas
Save the image

Try the imagemagick extension, its muchos better at image manipulation but its very hard to grasp as there is not much in terms of documentation on it.
