Get PriceHi i am trying to draw an ellipse using opencv but i have difficulty in understanding its angle arguments even it is not clear from the picture in opencv docs i tried following line eimg256256200100090180002554aa i got the result as below that means startangle is taken from positive x axis in clockwise direction and that is same for endangle
