Printing text with transparent background

[Odglog]

Hi
I'm creating a text console application. I have a function that takes a SMALL_RECT and fills the area with a given character. In my application, the background is going to be multicolored, the problem is when after changing the background color and I want to print a rectangle, I get a black background behind the text. So is there any way to tell the program to just print the text without changing the background color?

This is how I print the rectangles:

BOOL fillArea(const SMALL_RECT* lpScrollRectangle, WCHAR c)
{
	HANDLE hConsoleOutput = GetStdHandle(STD_OUTPUT_HANDLE);
	CONSOLE_SCREEN_BUFFER_INFO csbi;
	if (GetConsoleScreenBufferInfo(hConsoleOutput, &csbi))
	{
		CHAR_INFO fi = { c, csbi.wAttributes };
		if (!lpScrollRectangle)
		{
			csbi.srWindow.Left = 0;
			csbi.srWindow.Top = 0;
			csbi.srWindow.Right = csbi.dwSize.X - 1;
			csbi.srWindow.Bottom = csbi.dwSize.Y - 1;
			lpScrollRectangle = &csbi.srWindow;
		}
		return ScrollConsoleScreenBufferW(hConsoleOutput, lpScrollRectangle, 0, csbi.dwSize, &fi);
	}
	return FALSE;
}

void print(SMALL_RECT rr,WCHAR wc)
{
	SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), 5);
	fillArea(&rr,wc);
}


int main()
{
  //The background is already colored  

  print({5,5,10,10},'*');


  std::cin.get();
  return 0;
}

Since there are multiple colors, I don't want to waste time checking for the background color (if that's possible) on every character, I just want to passively print the text on the background, like a transparent text.

Thanks :)

There is no transparent, so it looks like you need to read each cell to find out what's there in order to combine it with what you want to print.
