Parameters
pBGR
Pointer to the source image ROI.
bgrStep
Distance in bytes between starts of consecutive lines in the source image.
pYCC
Array of pointers to the destination image ROI in each plane.
yccStep
Distance in bytes between starts of consecutive lines in the destination image.
roiSize
Size of the source and destination ROI in pixels.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts the 48-bit
BGR
image
pBGR
to the
YCoCg
image
pYCC
according to the following formulas:
Y = ((R + 2*G + B)+ 2)/4
Co = ((R - B) + 1))/2
Cg = (( - R + 2*G - B) + 2)/4
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error.
ippStsNullPtrErr
Indicates an error condition if one of the specified pointers is
NULL
.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
