Re: Hiw to use graphics in gforth?

[paul . ortais]

Hello Anton, Joe,

I wasn't the initiator of this request, but it directly relates to a 
concern of mine.
Though I can live with just at-xy and and scarce polices, the lack of 
graphics words in Gforth, and the reluctance to provide them in general 
in Forth, has something extremely bizarre that I concluded is a part of 
an "elite" club wanting to remain tiny.

Anton, in your answer to Joe,  I can hardly figure what "open a pipe" 
means in reality for me, or "through the C interface" etc.

Reading this I imagined that if only there is a single (Forth) word, for 
a given OS ok, to draw a pixel where I need it with graphic attributes, 
That would be cataclysmic in the Forth world. Like:
: Pix. ( RGB i j --)
  ????????
;
Then many would be in heaven.

And if this is out of reach, something like
: GraphPg. ( i j --)
  cols 0 do
    raws 0 do
      I maxcols * J + My-rgb-shadow-screen pix.
    loop
  loop
;
Would be the first step to an interview with St Peter.
Juste with that, we can do the maths.

But am I dreaming ?

(A bit of help to Joe)
Have wonderful times, thought lovers
Paul
