I think I'll start with SIXEL and add ReGIS later. http://www.macterm.net As long as you can get to the stream before macterm do, sure. Reading through all the blurb on that page actually never suggest that anything like that is possible, but it might be. I just couldn't find it.

But if you want to play with soft fonts, or sixel graphis (or ReGIS), you need to intercept the incoming byte stream to Terminal.app, and then interpret that stuff to pull out what you are expected to display. Johnny That was going to be my basic approach, write a little shim that looks for control chars and if it sees ReGIS/SIXEL it draws a canvas, otherwise it passes it along to Terminal.app.. Some guys did with PNGs and JPEGs in Python, this could be fun.. sampsa
