bool mindspore::dataset::GetRotationMatrix2D(float x, float y, double angle, double scale, LiteMat &M)
Matrix rotation.
- Example
/* Get Rotation matrix */ double angle = 60.0; double scale = 0.5; LiteMat M; GetRotationMatrix2D(1.0f, 2.0f, angle, scale, M); std::cout << M.width_ << " " << M.height_ << " " << M.channel_ << std::endl;
- Parameters
x – [in] The value of the x-axis of the coordinate rotation point.
y – [in] The value of the y-axis of the coordinate rotation point.
angle – [in] Rotation angle.
scale – [in] Scaling ratio.
M – [in] Output transformation matrix.
- Returns
Return true if transform successfully.
