add extra space [SOLVED]

[robjuffermans]

Hi,

I'm trying to resize images with a fixed height and variable width to a certain ratio 1:sqrt(2). If the image is too width then I can crop it, but if it's too small how can I make the width bigger without stretching up the image? So I just want to add extra space.

Regards, Rob
