iwiScale_GetScaleVals

Syntax



    
IW_DECL(IppStatus) iwiScale_GetScaleVals(
    IppDataType srcType,    
    IppDataType dstType,   
    Ipp64f     *pMulVal,    
    Ipp64f     *pAddVal     
);
Parameters
srcType
Data type of the source data.
dstType
Data type of the destination data.
pMulVal
Pointer to the multiplier used for scaling.
pAddVal
Pointer to the offset value for scaling.
Description
This function returns the multiplier and offset values to perform accurate data range scaling between two data types with the
iwiScale
 function.
Return Values
ippStsDataTypeErr
The
dataType
 value is illegal.
ippStsNullPtrErr
At least one of the pointers (except
pRoi

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
