Get RGB pixels from input image and reconstruct an output image in opencv

Question

I want to load the image in opencv and split the image into channels(RGB) and i want to increase any one of the colors and getting that corresponding output image.is there a

@karlphillip: Generally a better solution for RGB images - handles any padding at row ends, also parallelizes nicely with OMP !

for (int i=0; i < height;i++) 
{
    unsigned char *pRow = pRGBImg->ptr(i);
    for (int j=0; j < width;j+=bpp) 
    // For educational puporses, here is how to print each R G B channel:
      std::cout << std::dec << "R:" << (int) pRow->imageData[j] <<  
                          " G:" << (int) pRow->imageData[j+1] <<  
                          " B:" << (int) pRow->imageData[j+2] << " "; 
    }
}
