I am trying to draw a thick line using c++, and add a border to this line from all side. I am using moveto, lineto functions, but not sure how to track the line width to draw borders. this is require for generic line.
A:
The easiest way is to use an existing library to do this. The most popular libraries for C and C++ development are OpenGL, DirectX, SDL, and ALLEGRO. I'd recommend any of them other than DirectX for the purpose of keeping your code portable.
Hope this helps, good luck!

A:
You may have to use MoveTo and LineTo functions. As you didn't describe much about your need, not sure what exactly you want.

A:
If you only have MoveTo and LineTo, a simple way to draw what you describe is to draw a thick line from point A to point B, then a slightly narrower line from A to B again. It will look like the second line has a border around it in the colour of the first line.

this good suggestion, but sometimes i need to draw the thick street then draw a one pixel width border to give some effect like antilias
