Image rotation along the frame

I am trying to rotate an image but the out image has the black background at the tilted edges. I have attached both the input and output images. In the output image there is black background after rotation of the image. Could you please suggest how to avoid this. I need only my image in that place. When you see the brick.000 and brick.030 images even after rotation there is no black background in brick.030

You have to crop the image to get rid of the black border. If you want to get the same size as the input image the you have to resize it after cropping.
See this answer for more details. https://stackoverflow.com/questions/5789239/calculate-largest-rectangle-in-a-rotated-rectangle#7519376

Change it to as follows. The size mismatch is due to author not considering the color (3rd) dimension.
tl = round(max(size(B,[1 2])/2 - hw/2,1));
