Hi folks I've read that the implementation of Frank Markesteijn's X-Trans interpolation code in darktable is much faster than that in LibRaw or dcraw.
Is that correct? For better or worse I'm using LibRaw to extract regular raw Bayer image data and processing that myself, but for Fuji X-Trans and Foveon images I'm letting LibRaw::process() convert the image to a 3 colour RGB image and catching the output. Sad to say that the interpolation time for 3 passes of xtrans_interpolate() in LibRaw is might slow (40 seconds or so on my i7 lappie). So, if it is practical and you folks are OK with it, I'd like to "borrow/reuse" that code in DeepSkyStacker. Please could someone who knows point me to the relevant source code file on Github so I can take a look to see if I could adapt it in a subclass of LibRaw? If someone could indicate how this speed up was achieved I'd be most interested to know and also whether it might be OpenMP compatible? PS does Frank Markesteijn contribute here?
