AndreaMosaic is a small utility designed to create mosaics from photos.
For mosaic production, you need to make sure you use photos that will function as elements of an image mosaic, as well as a pic that is being used to build the mosaic matrix. Changing the settings will allow you to create various mosaic images if you already have it all.
With AndreaMosaic you can create photographic mosaics from your own photos. Each photographic piece of mosaic image is a photo and does not have a color, which is how mosaic works.
