The secret behind Block Indexed is the incredible accuracy. It was designed to keep the image in track, even in a huge magnetic storm. It is the right format for your survival kit, da Vinci would have chosen it to store the Mona Lisa.

BLINX stores portions of color values along with a position index value. One portion has a dimension of 16x8 pixels and consists of one color component only and is compressed with a simple run length encoding to ensure a lossless 8bit storing.

This index concept leads into a very stable image conservation. And BLINX is very easy to copy and move.
