[sane-devel] backend Kodak i260 Image depth 48 bits stream. How is coded?

Allan:

   A 1.5 bytes per pixel cool!. Maybe was my imagination, but I can see a 
odd repeated image when I open the RAW image with Photoshop CS2 with this options:

 1200 width, 1000 height, 3 channels, 16 bits depth and 0 bytes size header. 


  I'd put a zip-file with the RAW image on the next url 
  (a Windows-generated JGP image of the same car was included too)

   http://www.upitus.net/08354nussl68/imageCar.zip.htm

   and here too

  The scanner header-image date values are:

sounds like it is compressed. i think the 48 bit value is a red
herring. the i1860 requires something like 96 bits in that spot, even
though it only scans in 24 bit color.

no, shortened form of YCbCr.

sounds good. i might be able to figure it out.
