I need code for rotating an image in C++ which functions like imrotate function of matlab. Please suggest a good link. Or if someone can provide the code for imrotate.
Or at least please explain the algorithm.
Its not a homework. I need this code for my project. And we can use any external library or code.

<asp:ListItem>Rotate 180 degree Clockwise with a horizontal flip and vertical flip</asp:ListItem> <asp:ListItem>Rotate 180 degree Clockwise with a vertical flip</asp:ListItem> <asp:ListItem>Rotates 270 degree Clockwise but not flip the image</asp:ListItem>
rotate left: Shift + Ctrl + R or [ rotate right: Ctrl + R or ]
OpenCV2.0 has several computer vision and image processing tools. Specifically warpAffine (by defining the rotation matrix) will solve your problem with rotating an image.
The 2x3 transformation matrix mentioned in the documentation is as follows:
where θ is the angle of rotation and tx and ty is the translation along the x and y axes respectively.
You can get the source code here.
Also, OpenCV2.0 has many MATLAB-esque functions like imread, etc.
