Hi,

In Linux's textual enviroment (not in X, not by GTK+ or Qt lib),
how can I draw a line for example? or draw a blue circle?
with C or C++ ...

TIA and forgive me for my poor English written.

I suppose you want to use framebuffer device ? Look for SDL library so

Could you be please be more clear?

Because this question:

...could probably be answered best with:

Code:

#include <stdio.h>

int main()
{
    puts("--------------------------------");
    return 0;
}

...and I guess this is not what you mean...

And for a blue circle in textual mode, try :

Code:

#include <stdio.h>

int main()
{
    puts("\033[34m");
    system("banner o");
    puts("\033[0m");
    return 0;
}

There's also the nicely named libcaca:

Maybe something like this ...

Code:

convert -size 420x420 "xc:#FFFFFF" -draw 'line 225,200 200,200' test.jpg
or
convert -size 420x420 "xc:#FFFFFF" -draw 'circle 225,200 200,200' test.jpg

Hey, I haven't used banner for years!!!
I remember using it in Unix, but not in linux, most distros don't have banner
then I googled it and found the source.
You made me a happy man

...well for about 15 minutes
