Thanks for testing Animation Paper and evaluating it together with others.
The vision of Animation Paper is to do “traditional” animation in an easy, modern and digital way. So this doesn’t exactly scream for scanned drawings and peghole detection. However, we do have it on our list of wanted features because we do appreciate its usability and eligibility.
One great advantage of Animation Paper is that your drawings and lines done within Animation Paper is fully scaleable. So no matter how much you blow your drawings up they will stay crisp. No degradation or blurriness of your lines when lassoing and scaling/rotating. You are also able to work in one (lower) resolution and then export in a higher resolution once you are finished animating. But all this only works if you are drawing directly within the line engine of Animation Paper with, say, a Wacom tablet – if you on the other hand import scanned images they will be static bitmap with a finite resolution. I hope my explanation makes sense – please let me know 😉
