HI. What do you use to display your graphic? OpenGL? You should give more information if you would like us to help you

ohh sure i want to rotate it through c programmin usin putimage and getimage func i open it by using gmode ginit and gdriver

You have to calculate left and top based on the rotation you want combining with the getimage is done from.

As Shabbir says, this is pretty basic stuff. You can consider the line between the point of rotation and any given point (a pixel) as a vector. This vector can be expressed as an angle with respect to some coordinate system. To rotate it, one merely adds the angle of rotation. I suggest you review your trigonometry.

no i have already did that even if i use getimage i get the image in the memory but i cannot rotate through putimage as it only use top left corner and not the right corner and even try to get the coordinates and put the image in new coordinates and do rotation like this i used write algo but program gets terminated automatically and c gets closed

This is not a rotation-related phenomenon. I suggest that you deside what your REAL question is, then ask it as clearly as possible. "C gets closed"? C is a language. We don't get to use it anymore?
