Parameters
- pSrc
- Pointer to the source image.
- srcRoi,srcRoiL
- Region of interest in the source image (of theIppiRectorIppiRectLtype).
- srcSize,srcSizeL
- Size of the source image.
- srcStep,srcStepL
- Distance, in bytes, between the starting points of consecutive lines in the source image.
- scale[4]
- Coefficients by which the resulting RGB channels are multiplied after interpolation. By default, equal to 1.0.
- pDst
- Pointer to the destination image.
- dstStep,dstStepL
- Distance, in bytes, between the starting points of consecutive lines in the destination image.
- grid
- Specifies the configuration of the Bayer grid in the source image. The function copies 2-pixel width border pixels from the internal neighborhood pixels. The following values are possible:ippiBayerBGGRippiBayerRGGBippiBayerGBRGippiBayerGRBG
Description
This function operates with ROI (see
Regions of Interest in Intel IPP
).
This function transforms the one-channel gray-scale image
pSrc
that is produced by applying the color filter array (CFA) to 24-bit three-channel RGB image using the Variable Number of Gradients (VNG) demosaicing algorithm.
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error.
- ippStsNullPtrErr
- Indicates an error condition if one of the specified pointers isNULL.
- ippStsSizeErr
- Indicates an error condition if thesrcSizeorsrcSizeLhas a field that is less than 2, or if thesrcRoiorsrcRoiLhas a field with a negative or zero value.
- ippStsBadArgErr
- Indicates an error condition ifgridhas an illegal value.
