ResizeFilter

Changes the size of an image using a generic filter.

Syntax

IppStatus ippiResizeFilter_8u_C1R(const Ipp8u*
pSrc
, int
srcStep
, IppiSize
srcRoiSize
, Ipp8u*
pDst
, int
dstStep
, IppiSize
dstRoiSize
, IppiResizeFilterState*

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 is
NULL
.
ippStsStepErr
Indicates an error condition if
srcStep
or
dstStep
has a zero or negative value.
ippStsSizeErr
Indicates an error condition if
srcRoiSize
or
dstRoiSize
has a field with zero or negative value.
ippStsContextMatchErr
Indicates an error condition if a pointer to an invalid state structure is passed.
