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 YUV image
pSrc
, packed in the 4:2:2
sampling format, to the gamma-corrected RGB/BGR image pDst
for digital component
video signals in compliance with the ITU-R BT.709 Recommendation [ITU709] for high-definition TV (HDTV). The source YUV image has the
following sequence of bytes: UYV|YUY|VYU|YVY, ... . The conversion is performed
according to the following formulas:R = Y + 1.540*(V -
512)
G = Y - 0.459*(V - 512) -
0.183*(U - 512)
B = Y + 1.816*(U -
512)
The output RGB/BGR values are saturated to the range R [0..31], G
[0..63], B [0..31].
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.
