- Parameters:
handle – [in] Handle to the operator.
Must not be NULL.
stream – [in] Handle to a valid CUDA stream.
in – [in] input tensor / image batch.
out – [out] output tensor / image batch.
angleDeg – [in] angle used for rotation in degrees.
shift – [in] value of shift in {x, y} directions to move the center at the same coord after rotation.
interpolation – [in] Interpolation method to be used, see NVCVInterpolationType for more details.
- Return values:
NVCV_ERROR_INVALID_ARGUMENT – Some parameter is outside valid range.
NVCV_ERROR_INTERNAL – Internal error in the operator, invalid types passed in.
NVCV_SUCCESS – Operation executed successfully.
