Yes its better to read the document..I have tried for the rectangle...I that i have found one thing CvRect and cvRectagle() does the main thing..But for circle,is there any thing apart from cvCircle().

"Yes its better to read the document"

so DO it !

circle() is actually the first function in the first link. you did not find it, because you did not care to read it.

If you do not have enough time to read the manual why do you think we have enough time to answer your question? Is your time more valuable than ours?
