Parameters
- pSrc
- An array of pointers to ROI in separate planes of the source image.
- srcStep
- An array of distances in bytes between starts of consecutive lines in the source image planes.
- 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 fourth channel.
Description
This function operates with ROI (see Regions of Interest in Intel
IPP).
This function converts the planar
Y'Cb'Cr'
image pSrc
to the three- or
four-channel image pDst
.To compute gamma-corrected R'G'B'
(B'G'R'
) channel
values the above formulas are used. The difference is that ippiYCbCr411ToBGR
uses the input
data in the 4:1:1 sampling
format (see Table “Planar
Image Formats”
for more details). 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 ifroiSizehas a field with a zero or negative value.
