Obtains the rotation matrix required for affine transformation.

hi_s32 hi_mpi_vpc_get_rotation_matrix(hi_float_point center_point, hi_double angle, hi_double scale, hi_transform_matrix *matrix)

Parameter	Input/Output	Description
center_point	Input	Rotation center point of the input image.
angle	Input	Rotation angle. A positive value indicates anticlockwise rotation.
scale	Input	Resizing parameter. If the value of scale is greater than 1, the image is upscaled. If the value of scale is less than 1, the image is downscaled.
matrix	Output	Rotation matrix for affine transformation.
