Thanks i alraedy try it.

Core.bitwise_not(rgbaInnerWindow,rgbaInnerWindow);

but i got only a small ligne on the rigth of the image.

I tried to set another Destination Mat. But impossible to convert it after. And that crash the appli. See my previous post.

inverting is just bitwise_not

for a more general example, see here: https://github.com/opencv/opencv/blob...

There is no use of the bitwise_not on the ImageManipulationsActivity. there is one in the camera control but it is an camera.setColloEffect.

If you do not know said nothing.

o_O are you now saying that if it doesnt suit your direct needs, people should simply shut up? Seriously cv kids these days ...
