The first argument is the point where we rotate the image (in this case, the center cX and cY of the image). We then specify , the number of (counterclockwise) degrees by which we will rotate the image. In this case, we are going to rotate the image 45 degrees.

Web2D Rotation about a point. Rotating about a point in 2-dimensional space. Maths Geometry rotation transformation. Imagine a point located at (x,y). If you wanted to rotate that point around the origin, the coordinates of the new point would be located at (x',y'). x ′ = x cos θ − y sin θ y ′ = y cos θ + x sin θ. Where θ is the angle ... WebYou can use the counterclockwise one all the time, if you agree that a clockwise rotation would be a negative counterclockwise rotation.
