Correction?

First of all, excuse me about my english.

In the function resize_limitwh i wonder if the good code would be this one:

function resize_limitwh($imgwidth,$imgheight,$newfile=NULL)
{
list($width, $height, $type, $attr) = @getimagesize($this->imgFile);
if($imgwidth/$width < $imgheight/$height){
if($width > $imgwidth)
$image_per = floor(($imgwidth * 100) / $width);
}else{
if(floor($height >$imgheight))
$image_per = floor(($imgheight * 100) / $height);
}
$this->resize_percentage($image_per,$newfile);

}

As you can see this code compare the percentage of reduction aplied and choose the smallest one. I understand the purpose of this function is this one, isn`t it?

First of all, thanks for your class.

i have test the David code and well.. i think that is diferent the funcionallity.I prefer the original one.

I have found an error. The function _createImage().
In the first line of this function, you call $imgFile var, but this not declared. it's necessari to change for $this->imgFile to get the class value propierty.

thanks again

good class, change the line 210, because it removed some colors to PNG images, imagecolorstotal () is only for *. gif

if($this->imgType=='GIF' )
{
$colorcount = imagecolorstotal($this->_img);
if ($colorcount == 0) $colorcount = 256;
imagetruecolortopalette($newimg,true,$colorcount);
}
