nvjpeg2kEncodeParamsSetEncodeConfig()
***************************************
Sets the JPEG2000 header parameters that are defined in :ref:`nvjpeg2kEncodeConfig_t<nvjpeg2kencodeconfig-label>`.
This API should always be called during the encode process.

**Signature:**

.. code-block:: cpp

    nvjpeg2kStatus_t nvjpeg2kEncodeParamsSetEncodeConfig(
            nvjpeg2kEncodeParams_t encode_params, 
            nvjpeg2kEncodeConfig_t* encode_config);

**Parameters:**

.. list-table::
  :header-rows: 1
  :widths: 15 10 10 20

  * - Parameter
    - Input/Output
    - Memory
    - Description
  * - nvjpeg2kEncodeParams_t encode_params
    - Input/Output
    - Host
    - encode parameters handle
  * - nvjpeg2kEncodeConfig_t* encode_config
    - Input
    - Host
    - pointer to nvjpeg2kEncodeConfig_t


**Returns:**

:code:`nvjpeg2kStatus_t` - An error code as specified in :ref:`nvjpeg2kapireturncodes-label`



nvjpeg2kEncodeParamsSetQuality()
*********************************
This API allows the application to set the target PSNR value when lossy encode is required.


**Signature:**

.. code-block:: cpp

    nvjpeg2kStatus_t nvjpeg2kEncodeParamsSetQuality(
            nvjpeg2kEncodeParams_t encode_params, 
            double target_psnr);

**Parameters:**

.. list-table::
  :header-rows: 1
  :widths: 15 10 10 20

  * - Parameter
    - Input/Output
    - Memory
    - Description
  * - nvjpeg2kEncodeParams_t encode_params
    - Input/Output
    - Host
    - encode parameters handle
  * - double target_psnr
    - Input
    - Host
    - target PSNR value in db


**Returns:**

:code:`nvjpeg2kStatus_t` - An error code as specified in :ref:`nvjpeg2kapireturncodes-label`
