I have defined my object with the below function.
imshow(I);
h = impoly;
M = ~h.createMask();
I(M) = 0;
As an example I have attached an image with rotated object inside. I would be grateful if you could help me with that. The rotation angle, center point and distance from the center point is defined previously.

You have to crop the image, use imcrop(). Then rotate using imrotate(). After that it's just geometry and pasting. See attached copy and paste demo.

Many thanks for your answer. Actually when I want to use imrotate() in 'loose' method, image would not be displayed. I can't use 'crop' method due to the reason that I want to rotate selected part of image without any cropping. I would be grateful if you could help me with that.
