Is there any function to manipulate channels?

[Parad0x84]

I was wondering is there any function to discard channels from image, add blank channels and merge channels with another image?

[Parad0x84]

I guess there is not, so I tried to implement something like this, but it doesn't work as expected for less than 4 channel images(32 bit)
Image class has following members:
m_ImageData (std::shared_ptr<Color>)
m_ImageSize (custom struct with 2 integers)
m_ImageChannels(Channel count of image which is passed as desired channels when loading image from disk)

Color is just a wrapper around uint8_t. It just has 1 member

Is there anything wrong with this?

bool Image::SplitChannels(std::string* OutFiles)
{
if(!HasValidImage())
return false;

  Color** Buffers = new Color* [m_ImageChannels];

  for(int i = 0; i < m_ImageChannels; i++)
        Buffers[i] = new Color[m_ImageSize.X * m_ImageSize.Y];


  for(int j = 0; j < m_ImageSize.X * m_ImageSize.Y; j++)
  {
        for(int i = 0; i < m_ImageChannels; i++)
              Buffers[i][j] = GetRawData()[(j * m_ImageChannels) + i];
  }


  for(int i = 0; i < m_ImageChannels; i++)
        stbi_write_png(OutFiles[i].c_str(), m_ImageSize.X, m_ImageSize.Y, 1, Buffers[i], 0);

  return true;

}

Edit: I have no idea why github refusing to highlight first part of code, but I hope it's readable enough
