Convert XCF to SIX

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 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.
