Technically it may not be, but xterm has supported it approximately forever, and xterm is the de-facto standard minimum terminal emulator.

That's very helpful to know, thanks! So Sixels are a reasonably-popular de facto standard already, which I did not understand.

  They date to DEC terminals of the early '80s. DEC was involved in developing X Windows (competing with other windows systems like Sun's NeWS) and xterm supports many of the DEC terminal extensions to ANSI X3.64.

    early 90s, and i don't think xterm's sixel support is nearly that old

      I thought the VT240 had sixels as well as ReGIS, but now I'll have to look it up. Edit: (a) The VT240 (1984) did do sixels (§4.18.1 of VT240 Series Programmer Reference Manual). (b) xterm didn't add it until 2013. Maybe I was thinking of dxterm? Now I have to look that up. Edit 2: I was almost certainly thinking of dxterm. I can't find a specific reference for the Ultrix version (which I had used) but the VMS version (which I didn't) had sixel support circa 1990.

        aha, thanks for the correction; i thought it was vt320 and up only was that for images tho or just softfonts
        kps 3y ago
        Both. It's barely mentioned, though, and clear that they intended people to use ReGIS instead, presumably due to bitmaps not being very useful at 19.2K.

        just wait until the sixel hipsters find out about naplps and ripscrip
        kps 3y ago
        I hadn't heard of RIPscrip but NAPLPS/Telidon were big here — in the sense of talk and free money, not in the sense that anyone actually used them. (I remember the hype, but it was before my working life. I have a Telidon keypad in my hoard, though.) Thanks for the correction about xterm, BTW. I think I believed, until yesterday, that dxterm was an xterm derivative.

        sure, i wasn't really sure about xterm, and i appreciate you digging up the truth
