Well, if you dont want to reprogram dcraw, you can use it or a GUI version of it like my Image View Plus More 3 and set the parameters in the last steps such that they have no effect. Here I set toe = 0 gamma = 1, colourspace = raw, white balance = 1, 1, 1, and highlights = keep.
And the result:
Which can then be saved as 16bit png, or 16bit ppm or ...

I think this should be moved to Stackoverflow.
You can solve this problem. There is a clear indication that Libraw provides a good entry point. You can download additional demoisaicing methods here. So you could tap into that.
However, you probably have to do a bit of programming yourself, therefore this should be moved to StackOverflow.

An image has a fixed number of horizontal and vertical pixels. The DPI number just tells a printer (if the driver isn't used to override it) what the printed size of the ...

You can scale it up to a certain limit with acceptable quality. If the original image is very high quality you can do up-sampling with great success. The printer and image viewer will do it, but you want to control how it is done. If you are going to process the image and add effects, upsample first, so the added things will be the true output resolution.

Every digital image has a specific size: the width and height in pixels. The amount of information depends on that.
In digital image files, the number of pixels per inch is just a hint. It indicates a proportion that should be used for calculating the actual size of the image when printed.
If you have an image of 1000x1000 pixels and you print it at ...
