TextureEncodeBlock

Encodes a texture image to the BC4 format.

Syntax

IppStatus ippiTextureEncodeBlock_BC4_8u_C1R(const Ipp8u* pSrc, Ipp32u srcStep, IppiSize roiSize, Ipp8u* pDst);

pSrc	Pointer to the source image ROI.
srcStep	Distance in bytes between starts of consecutive lines in the source image.
roiSize	Size of the source and destination ROI in pixels.
pDst	Pointer to the destination image.

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

This function encodes a one-channel texture image ROI pSrc to BC4 compression format 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.
