Thanks, I used your code, but I have some doubts.

I tried x1 = 0, y1 = 0, x2 = 10, y2 = 4

With your code it should be:

0       0
1       0
2       0
3       1
4       1
5       2
6       2
7       2
8       3
9       3
10      4

I tried my initial idea, so a new picture, I draw a line and check pixel by pixel the color. Using new render (on osx) I have antialias and so many colours, using old render I have only black and white, but not same pixels.

0       0
1       1
2       1
3       1
4       2
5       2
6       3
7       3
8       3
9       4
10      4

Code of the test is available, just ask it.
Any suggestion? Have I to check every line I process? Seems I have to do it about 2'000'000 times for my project.
Thanks
Fabio Soggia
