I'm looking at it now, thanks.
What I would like to make is a drawing web app to allow users to draw individual inbetween frames of an animation. I want to be able to draw key frames ahead of time and have the app show two of them on screen at once at 50% opacity so the user can draw a new image over top, using them as guides. Then when they are done, press a button and save the image to become a new key frame to be served at 50% opacity to them or another user.
Does this seem possible? Here is a list of some things I would like it to do.
1. load images from a server (might get around this by just putting the images directly into the app and updating it as needed)
2. Save new generated images. (they could also just be saved within the app if that is easier) but I need to be able to get them out.
3. Unique user session to keep multiple people from working from the same images.
I realize request 3 might be difficult. Any thoughts?
