I was trying out the new addon. I was checking out to see if the background image to
the camera worked and it does work. Thanks.
I noticed something never had seen before. There are thin dark lines around the edges.
I noticed them more after I came from outside but now they are dimmer.
I eyes are getting used to the light inside the house.

I don't clearly see the problem in your image but for your description it seems something that could be fixed with pre-multiplied alpha

Maybe more white wall will make it a bit more obvious.

Where can I find the option: pre-multiplied alpha ?
Can not find it.

It is something the addon enables/disables internally when transparent background is enabled/disabled.
It should already work.

Can you upload the scene so I can check?

Here is the test scene for download:

I had a look at your scene yesterday.
I can get it to work correctly in the Blender compositor.
But the imagepipline plugin always shows dark edges, no matter if I disable/enable the premultiply alpha plugin.

Thanks,
It might not be a serious problem.
It might be something rarely seen.
