I see there is no CopyOpacity in the choices of composite. Is it gone for good? Is there a choice to take the place of it if it is gone for good?

Is there a CopyAlpha? Its the same as CopyOpacity.

I tried CopyAlpha. It does nothing. I used this on an image and nothing happened.

Doh! You must use the 'Intensity' composite op. It takes the intensity of the composite image and injects it into the alpha channel of the image.

Intensity doesn't work like CopyOpacity.

I used CopyOpacity on this image:

Using this mask:

Getting this result:

Using Intensity I get this:

As you can see you don't get the same result. I would be a happy camper if you could make Intensity work like CopyOpactiy or bring back CopyOpacity in version 7.00...

Thanks
