Parameters
- pSrc
- Pointer to the source image ROI. An array of pointers to the ROI in each separate plane of the source planar image.
- srcStep
- Distance in bytes between starts of consecutive lines in the source image. An array of such distances in bytes for each plane of the source planar 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.
- aval
- Constant value to create the fourth channel.
Description
This function operates with ROI (see Regions of Interest in Intel
IPP).
This function converts the
Y'Cb'Cr'
image pSrc
with 4:2:2
sampling
(see Table “Pixel-Order Image Formats”
and Table “Planar
Image Formats”
for more details) to the gamma-corrected B'G'R'
image pDst
according to the same
formulas as the function ippiYCbCrToRGB
does.The output
B'G'R'
values are saturated to the range [0..255].The fourth channel is created by setting channel values to the
constant value
aval
.Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error condition ifpSrcorpDstisNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSize.widthis less than 2 orroiSize.heightis less than 1.
