bool mindspore::dataset::GetRotationMatrix2D(float x, float y, double angle, double scale, LiteMat &M)

Matrix rotation.

参数

• 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.

返回

Return true if transform successfully.
