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.
- pSrcDst
- Pointer to the source and destination image ROI for the in-place operation.
- srcDstStep
- Distance in bytes between starts of consecutive lines in the source and destination image for the in-place operation.
- 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 takes the absolute value of each channel in each pixel of the source image ROI and places the result into a destination image ROI. It operates on signed data only. Note that the functions with the
AC4
descriptor do not process alpha channels.
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error condition if one of the specified pointers isNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSizehas a field with zero or negative value.
