Hi,
Thanks for your response. I actually dont know. But plz provide me the points where it should develop a Bezeir curve and provide me a reason for this linear behavior also.

Well, first have a look at Bézier curve description in Wiki.
Now take a sheet of paper, draw the XY-axes and put all your four points on the paper based on the coordinates you set:

Zulfi.

Why don't you think about it a bit. Come up with some points that don't form a straight line. Use a pencil and paper if you have to.

Hi,
Thanks for your advice and time. Actually i thought these are control points. Most slides show drawing of bezeir curves using control points. I thought its also using the same logic. Okay i would try with some non-linear points.
