To test the app, I took some screenshots of standard-sized application and file icons in Windows. A typical icon image is 32 by 32 pixels when displayed at desktop resolutions of 72 dpi--pretty small and, when you enlarge them, they look pretty chunky, like billboards made of Lego bricks. SmillaEnlarger's algorithm does a remarkable job of turning even an incredibly minute bitmap into something close to a blurry snapshot. While this is the full extent of its abilities, you might want to keep SmillaEnlarger in your digital imagery toolkit for a photographic rainy day.
