Hey everyone,

As you can tell from the the title, my problem is that the area of the ROI changes after I rotate it. For instance, I draw a ROI in the fist image, safe it to the ROI manager and measure the area, e.g. 10. I then apple the same ROI to a second image. Now I have to rotate the ROI a little bit, without changing the dimensions. When I now measure the area of the ROI in the second image, I get slightly different values for the are, e.g. 6. How do I fix this problem so that the ROI has the same area in both images, although rotated a bit?

I didn't found any solution to the problem on google, so I thought to ask around here. Hope one of you can help! Thanks a lot!
