I use canvas or maybe Wedge shape in kinetic framework to load 2 circle image, 1 for image background, 1 for image percentage of pie.
I bind touchstart, touchmove, touchend event for canvas container. Then i face 2 problem :
first thing how to use canvas load a portion of circle image. For example : just load 1/4 of image circle.
second thing is how to calculate portion of pie based on point of touch, when we touch down and move finger percentage of pie will increase and decrease as well.
please give me some suggestion or example. thanks in advance
