Best cropping method?

[atholon]

Hi there,

 

I am trying to figure out the best way to crop any image (with differing dimensions) to the same size without distorting it. My target thumbnail size would be 110 x 110.

 

Any ideas?

Here is part of a script I made awhile ago that will resize to a max width or height (depending on the layout of the image) and keep the ratio:

<?php
	$maxWidth = 300;
	$maxHeight = 225;
	move_uploaded_file($_FILES['upfile']['tmp_name'], "images/".$_FILES['upfile']['name']);
	$imgSize = getimagesize("images/".$_FILES['upfile']['name']);
	if ($imgSize[0] > $maxWidth && $imgSize[0] > $imgSize[1])
	{
		$newWidth = $maxWidth;
		$newHeight = ($maxWidth/$imgSize[0])*$imgSize[1];
	}
	else if ($imgSize[1] > $maxHeight)
	{
		$newWidth = ($maxHeight/$imgSize[1])*$imgSize[0];
		$newHeight = $maxHeight;
	}
	else
	{
		$newWidth = $imgSize[0];
		$newHeight = $imgSize[1];
	}
?>
