Parameters
pValues |
Pointer to the array containing values by which the source image is multiplied: one element for each channel. |
pSrcImage |
Pointer to the second image. |
pDstImage |
Pointer to the resulting image (can be the same as pSrcImage). |
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 |
---|---|---|
roundMode |
IppRndNear |
Rounding mode. |
algoMode |
IppAlgHintNone |
Accuracy mode. |
scaleFactor |
0 |
Scale factor. |
chDesc |
iwiChDesc_None |
IwiChDescriptor value. |
Description
This function multiplies an image by a constant value 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. |
