2017-09-12 04:21:35 -0600 | marked best answer | orientation angle of ellipse Hello everyone, I am having some trouble in understanding how the angle parameter of the ellipse function actually works. In the documentation it is meant to be anti-clockwise and referring to the main axis. Therefore, for instance, if I try to draw an ellipse of size (100,50) and angle 45 deg I expect it to be in the first quadrant while instead it is in the second. For instance this:
leads to the image below. Of course if I switch the axis the orientation gets correct but this seems to be in contrast with the image shown in the documentation. (opencv drawing doc) What am I misunderstanding? |
