GetUser3DLUTIndex 

Gets the index in the 3D LUT buffer corresponding to a triplet of red, green, and blue values.

Syntax 

ADLX_RESULT     GetUser3DLUTIndex (adlx_int lutSize, const ADLX_UINT16_RGB * rgbCoordinate, adlx_int* index)

Parameters 

  1. [in] lutSize adlx_int The size of the User 3D LUT.

  2. [in] rgbCoordinate ADLX_UINT16_RGB* The co-ordinates of a user 3D LUT.

  3. [out] index adlx_int* The pointer to a variable where the index is returned.

Return Value 

If the index of the 3D LUT from a flat array is successfully returned, ADLX_OK is returned.

If the index of the 3D LUT from a flat array is not successfully returned, an error code is returned.

Refer to ADLX_RESULT for success codes and error codes.

Remarks 

The 3D LUT table must contain between 5 and 17 points. Each point is defined by a triplet of red, green, and blue values.

GetUser3DLUTIndex is useful when constructing the 3D LUT buffer to set using SetHDRUser3DLUT , SetSDRUser3DLUT and SetAllUser3DLUT .

Additional Info 

Note: SetAllUser3DLUT sets a custom 3D LUT data for both the SDR mode and HDR mode of a display.

Setting a custom 3D LUT data suitable for the SDR mode of the display with SetSDRUser3DLUT will delete the custom 3D LUT data for the HDR mode that was previously created with SetAllUser3DLUT . If a custom 3D LUT data suitable for the HDR mode is also required, it must be set with SetHDRUser3DLUT .

Setting a custom 3D LUT data suitable for the HDR mode of the display with SetHDRUser3DLUT will delete the custom 3D LUT data for the SDR mode that was previously created with SetAllUser3DLUT . If a custom 3D LUT data suitable for the SDR mode is also required, it must be set with SetSDRUser3DLUT .
