YUV422ToRGB
Converts a YUV image with the 4:2:2 sampling to the RGB color model.
Syntax
Case 1: Operation on pixel-order data
IppStatus ippiYUV422ToRGB_8u_C2C3R(const Ipp8u*
pSrc

Parameters
- pSrc
- Pointer to the source image buffer for pixel-order image. An array of pointers to the source image buffer in each color plane for planar image.
- srcStep
- Distance in bytes between starts of consecutive lines in the source image for operations with ROI. An array of three values in case of planar image.
- pDst
- Pointer to the destination image buffer for pixel-order image. An array of pointers to the destination image buffers in each color plane for planar image.
- dstStep
- Distance in bytes between starts of consecutive lines in the destination image for operations with ROI.
- roiSize
- Size of the source and destination ROI in pixels.
- imgSize
- Size of the source and destination images in pixels for operations without ROI.
Description
This function converts the
Y'U'V'
image
pSrc
to the gamma-corrected
R'G'B'
image
pDst
according to the same formulas as the function
ippiYUVToRGB
does. The difference is that
ippiYUV422ToRGB
4:2:0 sampling
the input data to be in
4:2:2 sampling
format (see
Table
“Pixel-Order Image Formats”
and
Table
“Planar Image Formats”
for more details).
The function
ippiYUV422ToRGB_P3AC4R
additionally creates an alpha channel in the destination image with alpha values set to zero.
Some function flavors operates with ROI (see
Regions of Interest in Intel IPP
). The function flavors that do not use ROI operate on the assumption that both the source and destination images have the same size and occupy a contiguous memory area, which means that image rows are not padded with zeroes. In this case the step arguments are not needed.
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error condition ifpSrcorpDstisNULL.
- ippStsSizeErr
- ndicates an error condition ifroiSizeorimgSizehas a field with a zero or negative value.
