Need modifications in a C language project

Job ID: 39112135

Budget: $30 – $250 USD

I'm seeking an expert in data encoding libraries to modify the library from supporting 8 colors to 16 colors to store data. This upgrade will enable a 4-bit color combination instead of the current 3-bit setup. The main use case for this modification is document storage or encoding.

Key Responsibilities:
* Modify the library to support a new 16-color scheme.
* Ensure all encoding and decoding functions are compatible with the expanded color set.
* Update lookup tables, color-mapping logic, and bit-packing mechanisms as necessary.

Testing:
* I do not have test cases available. I will need you to create them to verify the extended functionality.

Ideal Skills:
* Extensive experience in C programming
* Strong background in image/color processing,data encoding and library modification.
