I have a little problem to draw lines into a BaseBitmap.
When all the lines are inside the area, it's ok, but when there is one point out of the bitmap area, the line is not drawn.

Is there a way to set a kind of clipping region for a basebitmap, to be able to draw lines who exceed the bitmap area ?

It's ok, I used the Cohen–Sutherland algorithm to make the clipping and it works fine !
For anyone who want ot use it : don't forget to use (Width - 1) and (Height - 1) for the size of the area in the algorythm, because it represent the max position pixel value (for 100 width, pixels X are 0 to 99).
