I've just tried reading raw format files from a couple of different cameras, and I'm immediately presented with an image. Perfect, thank you.
But ... you knew it was coming ... the images are all loaded as 24-bit RGB; where I know that at least some of the raw files contain 12-bits and 14-bits of information per channel per pel.
What I would like to do is be able to extract and save that information as a (say) 48-bit tiff file.
I suspect that this is not a sufficiently widely wanted feature to warrant adding it to the program, so I'm wondering if the raw-file read routines that IV uses are available as source?
I'm programmer and comfortable with writing tiff files using libTiff; I just need to be able to read the raw format(s) and get access to the data therein.
I'm specifically interested in .CR2, .arw and .rw2 mostly used by Panasonic and Canon.
I'd willing feed back anything I develop back to IV for inclusion if that was something that would fit.
Can you guys help me?
Thanks, Buk
