TextureDecodeBlock

Decodes texture BC4 blocks to the one-channel image.

Syntax

IppStatus ippiTextureDecodeBlock_BC4_8u_C1R(const Ipp8u* pSrc, Ipp8u* pDst, Ipp32u dstStep, IppiSize roiSize);

pSrc	Pointer to the BC4 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 ippiTextureDecodeBlock is declared in the ippj.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function decodes BC4 texture blocks pSrc to the one-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.
