I'm currently looking for a way to use a black and white bitmap to mask the alpha channel of another bitmap or Drawable on Android. I'm curious as to what the best way to do this is.

This seems to be a very common problem of mine: data = [1 2 3; 4 5 6]; mask = [true false true]; mask = repmat(mask, 2, 1); data(mask) ==> [1; 4; 3; 6] What I wanted was [1 3; 4 6]. Yes I can just reshape it to the right size, but that seems the wrong way to do it. Is there a better way? Why doesn't data(mask) return a matrix whe...
Hi all What I am trying to achieve might be trivial, however I am loading a PNG mask which does not have a transparent background, but rather a black background, with the shape defined on top in white (the actual mask which needs to be applied).

So my main portfolio class (the one where I'm assembling everything) calls an instan...
