[FAQ?] Graphics? Yes we can! about runcpm HOT 4 CLOSED

What I still haven't understood of Sixel graphics is how some applications manage to play animations and videos via Sixel functionality. I think I understood how to output graphics as if I'm commanding a 6 needles colour printer. But that's it for now.

On XTerm I see the graphics when XTerm gets the Sixel end command. Other terminals may behave differently. But there is a Xserver for Sixel terminals too and that gets updated whenever changes occur. That's still a mystery to me how that is done and "Read the (libsixel-)source, Luke!" is beyond my time budget and attention span.

The top msg contains a simple demo in HiTech-C.

I never thought RunCPM could do it ... :)

Sixel graphics behaves like a colour dot matrix printer but I did not use use colour to keep the example simple.

The Mandelbrot image is calculated in fixed point arithmetic to get an acceptable speed. With a maximum resolution of 1/4092 that sure is not able to yield deep zooms.

But I think it is ok as example and for wetting the appetite for more experiments.

Well... there is no standard for graphics with CP/M

Oh, yes, we already have a standard.

Its name is GSX (Graphics System eXtension) from Digital Research.
