Hello Alex,
   Regarding your comment above, I have few mroe queries, if you please can
answer.
  What if user manually enters below information needed in the Digikam tool for
thsi format file:
>> 1) image size (full size and real image size) 
>> 3) bayer pattern (this format is GRBG)

>> 2) black and white levels (possibly per-channel)
  What is this. data. Is it the two values for black and white?

>> 4) white balance data
What comprises of this data? Is it some color temperature or white point for
that temperature? Why is this data needed? 

>> 5) color data.
What is this data? Why is it needed?

Basically, why would white balance data and color data be needed in a raw file.
I don't want to any Image processing on it. All I want is to be able to use
Digikam to open this raw format(with user inputing some parameters to help it
interpret it), then convert it to some other format say DNG. and store the DNG
file.  
BTW, does DNG file format need White balance, Color data information ? 

thank you.
-AD.
