Hi, I need to paint the line witch links two points.

I developed my own solution using the straight line equation, but my results are different than using the "professional" programs (such as GIMP or even MS Paint).

Here is a example of what I want: alt text

But my algorithm does this: alt text

*The green point is out of the figure and this is not possible.

Any ideas? Anyone know which code is been using for this, in "professional" apps?

Thanks! Daniel.
