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.

NVCVStatus cvcudaRotateVarShapeSubmit(NVCVOperatorHandle handle, cudaStream_t stream, NVCVImageBatchHandle in, NVCVImageBatchHandle out, NVCVTensorHandle angleDeg, NVCVTensorHandle shift, const NVCVInterpolationType interpolation)

Functions

NVCVStatus cvcudaRotateCreate(NVCVOperatorHandle *handle, const int32_t maxVarShapeBatchSize)

Constructs and an instance of the rotate operator.

Parameters:

  • handle – [out] Where the image instance handle will be written to.

    • Must not be NULL.

  • maxVarShapeBatchSize – [in] maximum batch size for var shape operator

Return values:

  • NVCV_ERROR_INVALID_ARGUMENT – Handle is null.

  • NVCV_ERROR_OUT_OF_MEMORY – Not enough memory to create the operator.

  • NVCV_SUCCESS – Operation executed successfully.
