Good to know. Is there an example somewhere that shows how to do that in a step by step manner?

What I would like is to be able to load an image from the raw file as the camera generally would have the user see it using the user's white balance and so on, exposed as they see it on the camera's preview. Ideally, it would be ready to view and do further adjustments to if desired.

This sequence:

iProcessor.raw2image();
iProcessor.subtract_black();
iProcessor.dcraw_process();

resulted in a deep red image. Not correct at all.

If I load it with just this...

iProcessor.raw2image();

...I can, with a serious gaussian blur and a window and level adjustment, turn it into something close to what it should be.

So I'm still missing something.
