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* pState);

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.
