I am writing android app where I have a canvas that can be zoomed in or out and translated in any direction. Now what I need to know is what is the position of user finger ON CANVAS, not on screen. The problem is that I have to write this app with API 9 compatibility.
What I have achieved is that without scaling everything works well.
I learned a lot of information from this forum and will definitely use/visit it regularly. My profession is canvas photography. And I do job on tocanvas.net. I like to create photo to canvas. If any body in this forum interested in canvas print let me know.
I've implemented some kind of a vector map using Android's SurfaceView and a Canvas.
Each element of the map is represented by a path that is being drawn in a for loop that draws each path onto the canvas.
