Convert HEIC to SIXEL

The High Efficiency Image Container (HEIC) is a file extension used to store images and image sequences, leveraging the High Efficiency Image Format (HEIF). Developed by the Moving Picture Experts Group (MPEG) and introduced in 2015, HEIC files are acclaimed for their superior compression efficiency, which allows for high-quality images at smaller file sizes. This format is widely used in modern digital devices, including smartphones and cameras, to optimize storage capacity without compromising image quality. It supports advanced features such as live photos, burst photo sequences, and transparent images, making it integral for contemporary digital imaging solutions.

The SIXEL, or "six pixels", is a bitmap graphics format created by Digital Equipment Corporation (DEC) for their terminals and printers. Initially designed for DEC dot matrix printers like the LA50, it enabled the efficient transfer of bitmap graphics using a series of ASCII characters. Each character represents a 6-pixel high row, making it suitable for 7-bit serial communication. This format was later adapted for modern terminal emulators, extending its utility beyond its original scope.
