Parameters
pSrc
Pointer to the source image ROI.
srcStep
Distance in bytes between starts of consecutive lines in the source image.
pDst
Pointer to the destination image ROI.
dstStep
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
Cb'Y'Cr'
image
pSrc
, packed in the
4:2:2 sampling
format, to the 24-bit gamma-corrected
R'G'B'
image
pDst
according to the same formulas as the function
ippiYCbCrToRGB
does.
A
CbYCr
image has the following sequence of bytes:
Cb0Y0Cr0Y1
,
Cb1Y2Cr1Y3
, ... .
The output
R'G'B'
values are saturated to the range [0..255].
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr
Indicates an error condition if
pSrc
or
pDst
is
NULL
.
ippStsSizeErr
Indicates an error condition if
roiSize
has a field with a zero or negative value.
