Rotate an image without having a deformation

Hello,

I am trying to rotate an image by X degrees using imrotate. But if X isn't equal to 90 or -90, the image will be deformed. An example:

Is there any another solution?

From the documentation:

B = imrotate(A,ANGLE,METHOD,BBOX) rotates image A, where BBOX specifies

the size of the output image B. BBOX is a text string that can have

either of the following values. The default value is enclosed in braces

({}).

{'loose'} Make output image B large enough to contain the

entire rotated image. B is generally larger than A.

'crop' Make output image B the same size as the input image

A, cropping the rotated image to fit.

In other words, the default behavior does not crop the image. If the image is being cropped, it's either because you're cropping it, or it's because you're not using imrotate().

A = imread('cameraman.tif');
B = imrotate(A,20); % default behavior
imshow(B) % no cropping
