Syntax

IppStatus ippiResizeFilterInit_8u_C1R(IppiResizeFilterState* pState, IppiSize srcRoiSize, IppiSize dstRoiSize, IppiResizeFilterType filter);

Include Files

ippi.h

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib

Parameters

pState

Pointer to the state structure for resize filter.

srcRoiSize

Size of the source image ROI in pixels.

dstRoiSize

Size of the destination image ROI in pixels.

filter

Type of filter used in resizing; possible values: ippResizeFilterHann, ippResizeFilterLanczos

Description

This function operates with ROI (see ROI Processing in Geometric Transforms).

This function initializes the state structure pState for the resizing filter used by the function ippiResizeFilter. The size of the structure must be computed by the function ippiResizeFilterGetSize beforehand. The type of filter is specified by the parameter filter and it must be the same as in the function ippiResizeFilterGetSize.

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error.

ippStsNullPtrErr

Indicates an error condition if the pState pointer is NULL.

ippStsSizeErr

Indicates an error condition if srcRoiSize or dstRoiSize has a field with zero or negative value.

ippStsNotSupportedModeErr

Indicates an error condition if filter has an invalid value.
