)
IW_DECL(IppStatus) iwiDivC(
    const double        *pValues,    
    const IwiImage      *pSrcImage,

);

Parameters

pValues

Pointer to the array containing values by which the source image is divided: one element for one channel.

pSrcImage

Pointer to the image to be divided.

pDstImage

Pointer to the resulting image (can be the same as pSrc2Image).

pAuxParams

Pointer to the auxiliary parameters structure. If NULL, default parameters are used.

pTile

Pointer to the IwiTile structure for tiling. If NULL, the whole image is processed.

Auxiliary Arguments

Argument Default Value Description

rpundMode

ippRndNear

Rounding mode.

algoMode

IppAlgHintNone

Accuracy mode.

scaleFactor

0

Scale factor.

chDesc

iwiChDesc_None

IwiChDescriptor value.

Description

This function divides an image by a constant and puts the resulting image to pDstImage.

This function supports the following features:

Feature Support
In-place mode Yes
64-bit sizes No
Internal threading No
Manual tiling Yes
IwsTile simple tiling Yes
IwsTile pipeline tiling Yes

Return Values

ippStsDataTypeErr

The dataType value is illegal.

ippStsNumChannelsErr

The value for channels is illegal.

ippStsSizeErr

Values for size fields are illegal.

ippStsNullPtrErr

At least one of the pointers (except pTile) is NULL.

ippStsNoErr

No errors.
