SmillaEnlarger is a small graphical tool ( based on Qt ) to resize, especially magnify bitmaps in high quality. ( The used algorithm is an invention of my own )
No one would mistake the enlarged results as an original, unenlarged photo but the program works better than the other enlargement algorithms I've used. The new UI is intuitive.
Seems a very good algorithm. Enlarged a phone camera picture to 5 times original wilh the best method available in Serif Photoplus and with this program and this one definitely produced superior results. I wouldn't recommend doing that level of enlargement but I think I could get away with it if I wante a 64 inch by 48 inch image printed.
