I don't know how much ReGIS it supports, but it very definitely supports sixel graphics quite nicely: https://mediacru.sh/plKQQj7ymWNT https://mediacru.sh/plKQ

I don't know how much ReGIS it supports, but it very definitely supports sixel graphics quite nicely: https://mediacru.sh/plKQQj7ymWNT https://mediacru.sh/plKQQj7ymWNT The only limitation I've found is that the standard ppmtosixel conversion tool spits out 8-bit control-characters, but xterm seems to only recognise their 7-bit equivalents (hence the sed command in that screenshot).
