Look into run length encoding - much simpler than jpeg and the 
information is widely available. With only 4 colours you can use RLE4 
which saves even more space. 

Hi,

For the jpeg library, I am using a windows bitmap, which takes a
considerable amount of space. Since I am only using 4 colors, RGB and
black, I am looking at reducing the size of the bitmap input file.
Where and how can I configure the library so it can effectively use a
smaller input file for jpeg encoding?
