Convert SGI to SIX

The SGI file extension stands for Silicon Graphics Image, a raster graphics file format developed by Silicon Graphics Inc. primarily for their IRIS workstations. This format, originating in the late 1980s, supports uncompressed and RLE-compressed data with up to 48-bit color (16 bits per channel for RGB) and an alpha channel. SGI files are widely utilized in 3D graphics, visualization, and high-end imaging due to their ability to store high-quality images and intricate details, making them an essential asset in professional graphics and animation industries.

The SIX file extension, short for "six pixels", is a bitmap graphics format developed by Digital Equipment Corporation (DEC) for their terminals and printers. Introduced initially to send bitmap graphics to DEC dot matrix printers like the LA50, SIX later facilitated the transfer of soft fonts to terminals such as the VT220. This format encodes images using a series of six-pixel-high patterns, making it efficient for transmitting graphics over 7-bit serial links. Rediscovered around 2010, SIX remains in use with modern terminal emulators for tasks like video playback.
