Renderscript - processing 2 images

Question

Quickly going through the documentation I haven't found any obvious way of passing 2 images as inputs - has anyone done this or know if its possible with the current implementation?

Cheers, Josh

Kernel inputs are currently limited to a single allocation. You can pass additional allocations at the global scope and then use rsGetElementAt(thealloc, coords...) to get the data out of them.

Thanks Jason, do you know if there is a performance cost of using rsGetElementAt(thealloc, coords...)? At the moment I'm using NDK/OpenCV - runs fine on a Samsung Note but the Sony Z takes almost twice the time (which is why I'm looking at alternatives). – Josh Mar 17 '13 at 20:29
