CPlease complete this task as part of your GSoC 2018 application.
This challenge is mandatory if you apply for T720, T724
The goal is to build a small application which decodes a buffer with raw image data from the AXIOM Beta and converts it using the [LodePNG library](http://lodev.org/lodepng/) to create a viewable PNG image.
GitHub: https://github.com/lvandeve/lodepng# Create a simple C/C++ console application
Raw data (4096x3072, 12bit): http://files.apertus.org/AXIOM-Beta/snapshots/portraits/portrait-gainx2-offset2047-20ms-02.raw12
# Create simple C/C++ console application# Add lodepng.cpp and lodepng.h files in order to use LodePNG (no static or dynamic build was provided by the developer yet)
# Add lodepng.cpp and lodepng.h files in order to use LodePNG (no static or dynamic build was provided by the developer yet)# Read image data from a RAW12 file
# Read image data from RAW12 file into a buffer# Save one of the Bayer channels (any of them) as a grayscale 16-bit PNG using the LodePNG library
# Add routines to convert from 12bit to 16bit data and convert the every pixel from the image dataSample raw data (4096x3072, 12bit): [portrait-gainx2-offset2047-20ms-02.raw12](http://files.apertus.org/AXIOM-Beta/snapshots/portraits/portrait-gainx2-offset2047-20ms-02.raw12)
# Output 16bit PNG that can be viewedBonus points if the application runs on the [Axiom BETA firmware in QEMU](https://github.com/apertus-open-source-cinema/axiom-beta-qemu)
