Thank you Alex, this is exactly what I wanted. I can now get a raw undebayered buffer from LibRaw and display it on my image preview screen as a greyscale image. Of course, I see the bayer pattern on the preview display. Ultimately, I would like to be able to debayer the buffer using a nearest neighbour algorithm purely for the live preview screen and save a undebayered TIFF files.
This leads me onto my final question. Is it possible for LibRaw to return the camera bayer pattern, for example, RGGB, BGGR, GBGR or GRGB or is this not possible?
