LZD Image Compression/Decompression
« on: June 28, 2018, 12:39:25 am »
Hey all, I have been playing with compression. I made a Python program that compresses data, such as a TI Image, as well as a calculator program that can decompress such data to the graph screen.

While the Python program is general-purpose, the Z80 program assumes that the input is a compressed image, so you can mess things up! The neat thing is that in my example, the calc program (LZD) and the compressed data, along with their file headers, all came out to less than the size of the original image!
