Make a certain part of image transparant

Hi all,

 

I am trying to create a ColorSplash-alike app..

 

1. I have 2 ImageViews, one is on top of another.

2. The one on top is grayscaled, while the one below still have its color.

 

I would like to make a certain part of the grayscaled image become transparent (the part where the user touch), and then save it into a file.

 

I have been wondering for a while now.

 

Could anyone explain the logic behind this? Thank you..

Re: Make a certain part of image transparant

Divide one on top to 2 images. So then user touch interface this image disappears.
