Multitouch on HTC resistive screen honestly ? Phone ReviewsI'm not sure how you'd implement this into an actual ROM, but as an app it wouldn't be too challenging. I might give it a go myself if no-one else does.If you have an anchor point for the first finger then you know the point it reads when the second finger is placed will be equidistant from both fingers. It will also intersect the vector from finger A to finger B. So long as your first finger stays near this vector (ie. there's no twisting, just a pinch in a straight line) then you could quite easily work out the distance between your fingers and therefore the scale factor for the image.Ideas?
