Hi all. I am writing an app that will convert touchscreen user inputs (such as the user 'handwriting' on the screen) into vectors that can then be saved and recalled later. I need to get the vectors into a format I can store locally, either as a file or in an SQLite database. Just wondering if anyone had any pointers as to how to get started... my initial thought was to listen for MotionEvents and when an ACTION_DOWN is detected, record the coordinates and use this as the vector's start point, and then record intermediate coordinates as the ACTION_MOVE is triggered (used to help define the shape of this Path they are creating), ending the stroke vector on ACTION_UP... but this results in many many intermediate points per vector (30 or 40) and with several hundred vectors (a full page of handwritten text on a tablet for example) this solution gets quickly out of hand as each page will potentially require tens of thousands of points...
Any suggestions on a better way to represent and store user-inputed vectors/paths? Or maybe another approach completely? Thanks for any help!
