Syntax

public static class ColorLUTTrilinear

Methods

nppiLUT_Trilinear_8u_AC4IR(CUdeviceptr, Int32, NppiSize, CUdeviceptr, IntPtr[], Int32[])

Four channel 8-bit unsigned 3D trilinear interpolated look-up-table in place color conversion, not affecting alpha. Alpha channel is the last channel and is not processed. The LUT is derived from a set of user defined mapping points through trilinear interpolation.

Declaration

public static NppStatus nppiLUT_Trilinear_8u_AC4IR(CUdeviceptr pSrcDst, int nSrcDstStep, NppiSize oSizeROI, CUdeviceptr pValues, IntPtr[] pLevels, int[] aLevels)

Parameters

Type	Name	Description
CUdeviceptr	pSrcDst	In-Place Image Pointer.
System.Int32	nSrcDstStep	In-Place Image Line Step.
NppiSize	oSizeROI	Region-of-Interest (ROI).
CUdeviceptr	pValues	Device pointer aLevels[2] number of contiguous 2D x,y planes of 4-byte packed RGBX values
System.IntPtr[]	pLevels	Host pointer to an array of 3 host pointers, one per cube edge, pointing to user defined INPUT level values. (Npp8u*)
System.Int32[]	aLevels	Host pointer to an array of 3 user defined number of input/output mapping points, one per 3D cube edge.

Returns

Type	Description
NppStatus	StepError, NotEvenStepError, NullPointerError, AlignmentError, StepError, SizeError - ::NPP_LUT_NUMBER_OF_LEVELS_ERROR if the number of levels is less than 2 or greater than 256.

nppiLUT_Trilinear_8u_AC4R(CUdeviceptr, Int32, CUdeviceptr, Int32, NppiSize, CUdeviceptr, IntPtr[], Int32[])

Four channel 8-bit unsigned 3D trilinear interpolated look-up-table color conversion, not affecting alpha. Alpha channel is the last channel and is not processed. The LUT is derived from a set of user defined mapping points through trilinear interpolation.

Declaration

public static NppStatus nppiLUT_Trilinear_8u_AC4R(CUdeviceptr pSrc, int nSrcStep, CUdeviceptr pDst, int nDstStep, NppiSize oSizeROI, CUdeviceptr pValues, IntPtr[] pLevels, int[] aLevels)

Parameters

Type	Name	Description
CUdeviceptr	pSrc	Source-Image Pointer.
System.Int32	nSrcStep	Source-Image Line Step.
CUdeviceptr	pDst	Destination-Image Pointer.
System.Int32	nDstStep	Destination-Image Line Step.
NppiSize	oSizeROI	Region-of-Interest (ROI).
CUdeviceptr	pValues	Device pointer to aLevels[2] number of contiguous 2D x,y planes of 4-byte packed RGBX values
System.IntPtr[]	pLevels	Host pointer to an array of 3 host pointers, one per cube edge, pointing to user defined INPUT level values. (Npp8u*)
System.Int32[]	aLevels	Host pointer to an array of 3 user defined number of input/output mapping points, one per 3D cube edge.

Returns

Type	Description
NppStatus	StepError, NotEvenStepError, NullPointerError, AlignmentError, StepError, SizeError - ::NPP_LUT_NUMBER_OF_LEVELS_ERROR if the number of levels is less than 2 or greater than 256.

nppiLUT_Trilinear_8u_C4R(CUdeviceptr, Int32, CUdeviceptr, Int32, NppiSize, CUdeviceptr, IntPtr[], Int32[])

Four channel 8-bit unsigned 3D trilinear interpolated look-up-table color conversion, with alpha copy. Alpha channel is the last channel and is copied to the destination unmodified. The LUT is derived from a set of user defined mapping points through trilinear interpolation.

Declaration

public static NppStatus nppiLUT_Trilinear_8u_C4R(CUdeviceptr pSrc, int nSrcStep, CUdeviceptr pDst, int nDstStep, NppiSize oSizeROI, CUdeviceptr pValues, IntPtr[] pLevels, int[] aLevels)

Parameters

Type	Name	Description
CUdeviceptr	pSrc	Source-Image Pointer.
System.Int32	nSrcStep	Source-Image Line Step.
CUdeviceptr	pDst	Destination-Image Pointer.
System.Int32	nDstStep	Destination-Image Line Step.
NppiSize	oSizeROI	Region-of-Interest (ROI).
CUdeviceptr	pValues	Device pointer to aLevels[2] number of contiguous 2D x,y planes of 4-byte packed RGBX values
System.IntPtr[]	pLevels	Host pointer to an array of 3 host pointers, one per cube edge, pointing to user defined INPUT level values (Npp8u*).
System.Int32[]	aLevels	Host pointer to an array of 3 user defined number of input/output mapping points, one per 3D cube edge.

Returns

Type	Description
NppStatus	StepError, NotEvenStepError, NullPointerError, AlignmentError, StepError, SizeError - ::NPP_LUT_NUMBER_OF_LEVELS_ERROR if the number of levels is less than 2 or greater than 256.
