Function opencv::imgproc::get_rotation_matrix_2d

pub fn get_rotation_matrix_2d(
    center: Point2f, 
    angle: f64, 
    scale: f64
) -> Result<Mat>

Calculates an affine matrix of 2D rotation.

The function calculates the following matrix:

where

The transformation maps the rotation center to itself. If this is not the target, adjust the shift.

Parameters

• center: Center of the rotation in the source image.
• angle: Rotation angle in degrees. Positive values mean counter-clockwise rotation (the coordinate origin is assumed to be the top-left corner).
• scale: Isotropic scale factor.
