TextureDecodeBlockToRG

Decodes texture BC5 blocks to two-channel image.

Syntax

IppStatus ippiTextureDecodeBlockToRG_BC5_8u_C1C2R(const Ipp8u* pSrc, Ipp8u* pDst, Ipp32u dstStep, IppiSize roiSize);

pSrc	Pointer to the BC5 encoded source data.
pDst	Pointer to the destination image.
dstStep	Distance in bytes between starts of consecutive lines in the destination image.
roiSize	Size of the destination ROI in pixels.

The function ippiTextureDecodeBlockToRG is declared in the ippj.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function decodes BC5 texture blocks pSrc to the two-channel image and stores result in pDst.

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error if pSrc or pDst pointer is NULL.
ippStsSizeErr	Indicates an error condition if roiSize has a field with zero or negative value.
ippStsStepErr	Indicates an error condition if srcStep has a zero or negative value.
