demonstration of different resizing techniques using this image!

in order: bilinear, bilinear low quality, fant, adaptive sharp, lanczos, bicubic, bicubic smooth, nearest neighbor, and the last one is the big image resized by changing the width in html! they also have the names of the resizing method in the "title" attribute so it'll show if you mouse over.

this was done using paint.NET, a free image editing program whose website is, infuriatingly, not paint.net.

options looks like this in paint.NET (probably similar elsewhere)

(if you're curious, the image is a cover of a smutty 20s magazine (public domain!) that i edited to tidy up a bit because i like the covergirls.)
