Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance in bytes between starts of consecutive lines in the source image buffer.
- srcRoiSize
- Size of the source image ROI in pixels.
- pDst
- Pointer to the destination image ROI.
- dstStep
- Distance in bytes between starts of consecutive lines in the destination image buffer.
- dstRoiSize
- Size of the destination image ROI in pixels.
- pState
- Pointer to the state structure for the resize filter.
Description
This function operates with ROI (see ROI Processing in Geometric
Transforms).
This function resizes the source image
pSrc
using the special generic
filters. The state structure pState
contains the parameters of filtering and must be initialized
by the function ippiResizeFilterInit
beforehand.Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error.
- ippStsNullPtrErr
- Indicates an error condition if one of the specified pointers isNULL.
- ippStsStepErr
- Indicates an error condition ifsrcStepordstStephas a zero or negative value.
- ippStsSizeErr
- Indicates an error condition ifsrcRoiSizeordstRoiSizehas a field with zero or negative value.
- ippStsContextMatchErr
- Indicates an error condition if a pointer to an invalid state structure is passed.
