Also I forgot to add that
Code: CPP
BOOL TransparentBlt(
  HDC hdcDest,
  int nXOriginDest,
  int nYOriginDest,
  int nWidthDest,
  int hHeightDest,
  HDC hdcSrc,
  int nXOriginSrc,
  int nYOriginSrc,
  int nWidthSrc,
  int nHeightSrc,
  UINT crTransparent
);
can also help but its for transparent output.
