The ActionComponents.ACImageView is a custom ImageView with built-in helper routines to automatically handle user interaction such as dragging (with optional constraints on the x and y axis), events such as Touched, Moved and Released and image loading, scaling and rotation. The ActionComponents.ACImageView includes a DisposeImage method to release the memory being held by an image Bitmap. Memory will automatically be purged before loading a new image into this ActionComponents.ACImageView. More...
