Fun Stuff!

Hi ho! I would like to ask another question.

 

I have a function that allows me to scale an image, how would I do it as a class?

function image_resize($iImage, $allowedwidth, $allowedheight)
{
   list($width, $height, $type, $attr) = getimagesize($iImage);

      if($width > $allowedwidth || $height > $allowedheight)
       {
         
          if ($width > $height)
          {
            $offset = $width / $allowedwidth ;
            if ($offset<=1)
            {
            $offset = $width - $allowed;
            $newimagewidth =$width - $offset;
            $newimageheight =$height - $offset;
            }
            else
            {
            $newimagewidth =$width / $offset;
            $newimageheight =$height / $offset;
           }            
    
          }
          elseif ($width < $height)
          {
             $offset = $height / $allowedwidth ;
            if ($offset<=1)
            {
            $offset = $height - $allowed;
            $newimagewidth =$width - $offset;
            $newimageheight =$height - $offset;
            }
            else
            {
            $newimagewidth =$width / $offset;
            $newimageheight =$height / $offset;
            }            
          }
}

you don't need a class.. this is single function!

[atholon]

it will be called many times though for different variables.

 

[teng84]

function can be called may times ? then whats the problem with that.

it will be called many times though for different variables.

 

 

 

If you are resizing images so many times maybe you should think about making multiple copies initially stored in the desired sizes to save time.

lol I am trying to apply classes but I don`t understand when you'd need one then.

I can't seem to get it to return the values correctly.

 

     if (isset($image2))
   {
     image_resize($image2, 100, 100);
     echo("<br><br><div align=\"right\"><a href=\"$image2\" target=\"_blank\"><img border=\"0\" border=\"#C0C0C0\" src=\"$image2\" width=\"$newimagewidth\" height=\"$newimageheight\" align=\"top\"></a>");
     }
