I need a component which handles touch events and checks against a
number of masks to see which region encloses the touch.
Does such a component exist already?
I started working on implementing a simple version but am currently
hung up on how to read the value of a pixel from an image. Context:
I've got a background PNG image.
I've captured a touch on the image.
I'd like to look up the coordinates in one or more auxillary
bitmap images (masks) to see if
the user has clicked on a section of interest.
Any clues?
Many thanks in advance!
Ken
