Ben,

I'll be using the library for an annotation tool. Where I have an image as background and use the library to draw and comment onto the image.

Then I'll save the annotations as a separate transparent png to the server and any textboxes as an array to maintain editability.

The thing I'm not certain about is keeping the annotations editable. So once I load an annotation image I can use the eraser tool on it etc. And then resave it as a new image. Can you give me some tips on how I can load the image in and make it editable(like a breakapart at runtime)?
