I want to be able to combine an image and the output from peninput.
Concept Use: User takes picture with phone, adds notations/text using PenInput, combined image + peninput is then saved somewhere.
Concept Implementation: Add "Background Image" property to the PenInput. Then, in my app - I can set the Background image to something from my camera or elsewhere. PenInput is a layer on top of background image. Output is background + Pen layer.
Other Concept: Create SET method for IMAGE property on PenInput. Then, user is able to SET the image + modify image. GET Method then returns the combined image automatically. This method allows for some different functionality as then users are technically able to edit the base image (erase parts of the image).
Ideally, the combined image + peninput will be stored in base64 binary.
