Can't you just divide the width and height by the same number?

 

eg. To halve the size output it at (width / 2) x (height / 2)

 

Seems easiest way to me..

below is the code i used.. hope it will help..

 

function r ($image,$size,$dir,$ext_name="", $tocopy=0, $todir='')
{		


	$path_to_file = $dir;
	$image=$path_to_file.$image;

	if(file_exists($image)) {
		list($imgWidth,$imgHeight,$type,$imgAttr)=getimagesize($image);
		$tempno = max($imgWidth, $imgHeight);
		if($tempno > ($size - 1)){
			$proportion = ($size / $tempno);
			$width = round($imgWidth * $proportion);
			$height = round($imgHeight * $proportion);
		} else {
			$width = $imgWidth;
			$height = $imgHeight;
		}

		$ext=getFileExtension($image);
		$ext=".".$ext;
		$image=ereg_replace($ext, "", $image);
		resize($width,$height,"$image"."$ext_name");
	}
}
