ok thanks

, what i want to do involves both simple and `hard` transformations:
1. zoom in/out ; mouse wheel will just zoom in/out on the image
2. Drag and drop:
Suppose that A (rectangle)is my Picture Ctr,and B is my image.
Normally B is exactly the size of A and the size of the image.
When i click and drag the image in the Picture Ctrl the image will follow my mouse , so when i move right the image will move right. The backgound will be white or black

Hard:
3. Rotate the image in the 2D space.
When i click the corner of the image for example, the picture will rotate around the center.
4. Rotate in 3D space. But i'm not sure if i want to do this.
Imagine you are looking to a plane in space from (0,0,0). The image is at (1,0,0) with the normal (-1,0,0) facing you.
You should be able to rotate the image about Y and Z only around the origin.

Thanks,
Raxvan.
