  Do you mean in terms of hit testing? Gideros already makes use of the alpha channel when drawing bitmaps...

  I have almost finished game and I need to create custom sized scrollview/tableview with results. I got stuck with this because of custom mask for Shape/Sprite
  
  (sorry for my english)

  It looks like you need some sort of clipping. Unfortunately, I think this is not supported..? Can any developer comment here?
  
  You should post some code, I think.

  Yeah, for example, me, I can't still understand what the problem is. Any code, example, video, screenshot would be helpful

  @pykaso, masking is not yet a feature available, which can limit a few things. However there are ways to overcome this and visually achieve the result you want (not a very good solution, but gives the visual result)

  as @OZapps said there are solutions, like putting Bitmap (with transparent center) on top of it. Or Shape object, that fills everything around. There's probably even a solution with Meshes, which could be even more efficient.

  @ar2rsawseen Is it possible to have a Shape with a hole in it? Or would you need multiple shapes?

  @john26 no not in the middle, but you also don't need multiple shapes. Imagine as it is a huge fat snake biting its own tail, this way you can (in circular way) draw the same with one Shape.

  @john26 and @ar2rsawseen - couldn't you just use a very thick stroke on the shape? I haven't messed with shapes much so don't know if it's possible or not, but wouldn't that give you a hole in the middle?
  
  Either way, masks and clipping are desperately needed.

  @moopf
  set the line style thickness to a large number and you have a thick stroke.
  
  Update: Oh Sorry, you were not asking, but suggesting
