Invert layer button!

What do you mean precisely by 'invert'?
Invert the pixels of a media as in make all black pixels white and all white pixels black? Or invert, or 'flip' a layers orientation?
With pixels you can use the filters to do this.
With orientation you can use the rotation Z.
Unless there is something else you mean by invert?
