color value = image[pixel number][COLOR(row,col)], indeed, but it is not intended to use this way.
If one uses dcraw_process(), he will get image[] with interpolated colors after this call.
If one uses own processing, he hardly need 4-component image[] array.
raw2image is *compatibility layer* for some programs created to use with Libraw pre-0.15 (separate raw_image and image was introduced in version 0.15).
