Rick Brewster has replied in another thread that downscaling uses « supersampling » and upscaling uses bicubic, which is clearly stated in the GUI when resizing. However, I still think that a sharp Lanczos resize should be added (I can even code it if required...) and will produce much better result than the bicubic and better results than bicubic + sharpen.

I have not found a similar request on the forum. I have noticed, when upsizing a picture, that the resize algorithm could yield better (in my opinion) results. A resize by a factor 2 for example is much sharper and better looking when performed with video editing tool AviSynth (using function LanczosResize()) than with Paint.NET, which yields a blurred picture. I would suggest implementing LanczosResize or a similar sharp resize. Before someones ask and tells me upsizing is bad, I had done that because I was convinced that by using the suitable software I could make a better looking picture than leaving this task to the photo book printers (photoways.com).
