Re: How many colors?

Cool!

I'm glad you like it.

I'll have to get my stuff together and release version 10.0.
It uses function pointers that get set only once whenever a change is made
to the frame buffer resolution. That way the right function gets called
automatically with no time wasted on a switch statement. It is WAY faster
than the version that is on the web now. It is written in C, but it acts
like C++.

I guess I don't really understand your first question. You can't get more
than 16 colors out of any terminal because the program that runs to display
in the terminal has no way to ask for more than the 16 usual colors. The
colors are set with escape sequences; a coded string of characters. These
can also set absolute cursor position anywhere on the screen and do other
things like reverse the text foreground and background or make it blink.
It's not really graphics at all. You have no pixels; only character cells;
and it is (supposed to be) OS independent.

James.   :o)
