Вот фрагмент файла GreyMultiBitmap.cpp, начинающийся со строки 9:

Код: Выделить всё

template 
std::shared_ptr CGrayMultiBitmapT::CreateNewMemoryBitmap() const
{
std::shared_ptr pBitmap;
if (static_cast(m_pBitmapModel))
{
CBitmapCharacteristics bc;
m_pBitmapModel->GetCharacteristics(bc);
if (bc.m_lNrChannels == 1)
return m_pBitmapModel->Clone(true);
else
{
bc.m_lNrChannels = 1;
return CreateBitmap(bc);
}
}
return std::make_shared();
}

Кто-нибудь может объяснить:
