The .six file extension is used for raster images saved in the Sixel format. Developed in the 1980s by the Digital Equipment Corporation, this image type was initially meant to be printed by a DEC dot matrix printer. Sixel is a graphics compression technique. It is named after the six pixels that are used in each cell of an image. Sixel images are made up of a series of cells. Each cell contains six pixels. The pixels are arranged in a rectangular grid. It could also be displayed on a computer terminal. Other manufacturers, notably HP, later adopted the file format. Today, six files can be viewed and converted with programs like ImageMagick.
