DEC Six Pixels (.six)

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.

The High Efficiency Image File Format (HEIF) is a modern image format designed for superior compression efficiency and enhanced image quality. Originating in 2015, HEIF was developed by the Moving Picture Experts Group (MPEG) and utilizes the High Efficiency Video Coding (HEVC) codec to store image data. It supports a wide range of multimedia applications, including single images, image sequences, auxiliary image items, and non-image items, making it highly versatile for professional and consumer usage in various devices and platforms. Its ability to maintain high image quality while reducing file size significantly improves storage efficiency and accelerates data transmission.
