Hi! Interesting format - I was expecting a DNG-like format (TIFF structure with LJPEG data).
* How do I differentiate between a JP4 and JPG image, beside the extension. * Is there documentation for the makernote other than the java code? * The colorspace - is it fixed, or read from EXIF - can we expect an ICC profile? I cannot see any big issues in supporting modes 0-2 in Rawstudio, since it seems like a pretty basic adjustment of the ordinary JPEG loader into a separate loader. I'm not sure it belongs in Rawspeed at the moment, since it is more related to JPEG rather than uncompressed RAW data, but I could add a basic framework which loads images through libjpeg. I would have to make a minor adjustment to the framework, since it only handles TIFF-based images at the moment, but that part isn't a big issue. I think the easiest proof of concept is to implement a loader in Rawstudio, and move the reordering/un-gamma into RawSpeed. Regards, Klaus Post http://www.klauspost.com
