If an image has a lot of curved/diagonal lines, upscaling will make everything blurry, but these lines will be more faithful. <br /><br />This picture has a lot of rounded lines in there, and these will all be more accurately represented after upscaling. Try the same on something with mostly vertical/horizontal lines, and the result will be much poorer. <br /><br />Basically, this is just spatial anti-aliasing doing its magic. inachoshttps://www.blogger.com/profile/01797318008249681236noreply@blogger.com
