Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance, in bytes, between the starting points of consecutive lines in the source image.
- pDst
- Pointer to the destination image ROI.
- dstStep
- Distance, in bytes, between the starting points 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 the starting points of consecutive lines in the source and destination image for the in-place operation.
- roiSize
- Size of the source and destination ROI, in pixels.
- pBuffer
- Pointer to the work buffer. To compute the size of the buffer, use theippiWinHammingGetBufferSizeorippiWinHammingSepGetBufferSizefunction.
Description
These functions operate with ROI (see Regions of Interest in Intel IPP).
These functions compute the Hamming (triangle) window samples, multiply pixel values of the source image
pSrc
(pSrcDst
for in-place flavors) with these samples, and store results in the destination image pDst
( pSrcDst
for in-place flavors).The Hamming window function for one-dimensional case with 
M
elements is defined as follows:
The
ippiWinHammingSep
flavor applies the window function successively to the rows and then to the columns of the image.Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error whenpSrcorpDstpointer isNULL.
- ippStsStepErr
- Indicates an error whensrcStepordstStepvalue is zero or negative.
- ippStsSizeErr
- Indicates an error when width or height of images is less than, or equal to zero.
