I am using the roi = drawellipse command from the image processing toolbox (https://www.mathworks.com/help/images/ref/drawellipse.html) to label some elliptical shapes in image.
This returns an Ellipse (roi) object. One property is the "Rotation angle" which according to the documentation (retrieved 30.11.2021) is:
- Rotation angle of the ROI, specified as a number. The angle is measured in degrees in a clockwise direction around the center of the ROI.
However, if I rotate by hand the ellipse in a COUNTER clockwise direction, the angle increases (thus the angle is measured in degrees in a counter clockwise direction). Is this a typo in the documentation or am I missing something?
I am using:
