Convert XCF to SIXEL

The XCF (eXperimental Computing Facility) file extension is the native image format of the GIMP image-editing program. It stores comprehensive image data, including layers, channels, transparency, paths, and guides, facilitating non-destructive editing. Developed by GIMP, XCF ensures all editing information is preserved, allowing users to revert to any editing stage. While primarily used within GIMP, some other programs also support XCF files.

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.
