iwiColorConvert

Syntax

class IwiColorConvertParams: public ::IwiColorConvertParams
{
public:
    IW_BASE_PARAMS_CONSTRUCTORS(IwiColorConvertParams, iwiColorConvert_SetDefaultParams)
    IwiColorConvertParams() {}
};
IW_DECL_CPP(IppStatus) iwiColorConvert(
    const IwiImageArray         &srcImages,
    IwiColorFmt                  srcFormat,
    IwiImageArray               &dstImages,
    IwiColorFmt                  dstFormat,
    Ipp64f                       alphaVal   = IwValueMax,
    const IwiColorConvertParams &auxParams  = IwiColorConvertParams(),
    const IwiTile               &tile       = IwiTile()
);
Parameters
srcImages
The array object of source images.
srcFormat
Color format of the source images.
dstImages
The array object of destination images.
dstFormat
Color format of the destination images.
alphaVal
Value to set to the alpha channel in case of
X
->
XA
 conversion.
auxParams
Reference to the auxiliary parameters structure.
tile
Reference to the
IwiTile
 object for tiling. By default, no tiling is used.
Description
This function performs conversion between basic color formats: Gray, RGB, BGR, RGBA, BGRA. For more information about the supported color models and conversion process, refer to Color Conversion.
Exception Values
ippStsSizeErr
Values of the
size
 fields are illegal.
ippStsInplaceModeNotSupportedErr
In-place operation is not supported:
pSrc
 is equal to
pDst
.
ippStsNullPtrErr
At least one of the pointers (except
tile
) is
NULL
.
Return Values
ippStsNoErr
No errors.

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.
