Getting RGB values for each pixel from a raw image in C

Question

I want to read the RGB values for each pixel from a raw image. Can someone tell me how to achieve this? Thanks for help!

the format of my raw image is .CR2 which com

Answer 1

None of the methods posted so far are likely to work with a camera "raw" file. The file formats for raw files are proprietary to each manufacturer, and may contain exposure data, calibration constants, and white balance information, in addition to the pixel data, which will likely be in a packed format where each pixel can takes up more than one byte, but less than two.

I'm sure there are open-source raw file converter programs out there that you could consult to find out the algorithms to use, but I don't know of any off the top of my head.

Just thought of an additional complication. The raw file does not store RGB values for each pixel. Each pixel records only one color. The other two colors have to be interpolated from heighboring pixels. You'll definitely be better off finding a program or library that works with your camera.
