Processing TIFF/PNG Layers

Greetings: Does anyone know where I can see an example of how to process/add layers to a TIFF image? I want to be able to grab an image, separate the layers (CGLayer?) into their separate contexts for the user to work with; and add a new transparent layer.

Specifically,
1)  allowing the user to draw/edit upon a layer above a static layer per
button.

2) Combine the layers back into the TIFF/PNG for storage.


I believe the same could be done with a PNG image?


Regards,

Ric,
neophyte.
