GrayToRGB
Coverts a gray scale image to RGB/BGR by copying luminance component to color components.
Syntax
IppStatus ippiGrayToRGB_<mod>(const Ipp<datatype>* pSrc, int srcStep, Ipp<datatype>* pDst, int dstStep, IppiSize roiSize);
Supported values for mod:
8u_C1C3R | 16u_C1C3R | 32f_C1C3R |
IppStatus ippiGrayToRGB_<mod>(const Ipp<datatype>* pSrc, int srcStep, Ipp<datatype>* pDst, int dstStep, IppiSize roiSize, Ipp<datatype> aval);
Supported values for mod:
8u_C1C4R | 16u_C1C4R | 32f_C1C4R |

Libraries: ippcore.lib, ippvm.lib, ipps.lib, ippi.lib
Parameters
pSrc |
Pointer to the source image ROI. |
srcStep |
Distance, in bytes, between the starting points of consecutive lines in the source image. |
pDst |
Pointer to the destination image ROI. |
dstStep |
Distance, in bytes, between the starting points of consecutive lines in the destination image. |
roiSize |
Size of the source and destination ROI, in pixels. |
aval |
Constant value to create the fourth channel. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP ).
This function converts a gray scale image to an RGB/BGR image by copying luminance component to color components.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error. |
ippStsNullPtrErr |
Indicates an error when pSrc or pDst is NULL. |
ippStsSizeErr |
Indicates an error condition if roiSize has a field with a zero or negative value. |
Example
The code example below demonstrates how to use the ippiGrayToRGB_8u_C1C4R function.
const int WIDTH = 2; const int HEIGHT = 1; Ipp8u pSrc[WIDTH * HEIGHT] = { 113,113, }; Ipp8u pDst[WIDTH * HEIGHT * 4]; int srcStep = WIDTH, dstStep = WIDTH * 4; IppiSize roiSize = {WIDTH, HEIGHT}; IppStatus status = ippiGrayToRGB_8u_C1C4R(pSrc, srcStep, pDst, dstStep, roiSize, 0xFF); if ( status == ippStsNoErr) { printf("PASS:\n(%3d %3d %3d %3d), (%3d %3d %3d %3d)\n", pDst[0], pDst[1], pDst[2], pDst[3], pDst[4], pDst[5], pDst[6], pDst[7]); } else printf("FAIL: status = %d\n", status);
Result:
PASS: (113 113 113 255), (113 113 113 255)
