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 whenpSrcorpDstisNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSizehas 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)
