Trying to use the trick...

I took the unprocessed_raw.cpp, clean it a little bit the code and processed a 11MB image raw file, but the resultant have 55MB, so i assume that there is a post-processing when saving the file in .tiff format.

I basically want to extract the raw image data, without metadata, read it, make a little processing and then save it in a new file.

In order to do that, your suggestion looks what i need to do, but can you please give a reference code about how to implement it?. I'm not asking for an elaborate coding, only a few lines in order to follow the idea.

I'm not c++ expert, so if the question is basic or simple, i'm sorry.
