I have A 65kb image (Dimension 256 X 256), uncompressed in BMP format. i want to compress that image using this algorithm but the dimension changes. I want o maintain the same 256 X 256 dimension after compression. I am not sure is it possible or not. if yes, how?

Very clean code, very easy to use and understand. Recommended if you are trying to learn about compression algorithms!

Not a good implementation. The performance is so bad even for a 512x512 size of image.
