I want to know if there is a function with which we can smooth out line joining two( or more )points . I've read we can do it with Quad and cubic splines or something but I am not clear with them. i want a simple function which can be computed efficiently with a mobile device , so can someone explain Quad spline .Help appreciated

This picture shows my requirement.

    I guess that every mobile device offers some API, like HTML5 canvas, that supports splines out of the box. Why not use a standard solution?2012-06-03

    because they don't let you get points out of a path and then tweak with that points before drawing . I am developing an android drawing app and using a path does smooths my line but then i can just draw solid along that line , i wish to draw bitmaps along that smoothed path but android canvas has canvas.drawpath(path,paint) alone .2012-06-03
