L_VOID LBitmapWindow::SetROP3(uROP3)
Sets the Windows ROP3 code to use when painting.
The Windows ROP code that determines how the bitmap is updated. This parameter takes the same codes as the Windows BitBlt function. For ordinary painting, use SRCCOPY.
None.
The default (for normal painting) is SRCCOPY. You can specify any of the ROP3 codes that the Windows BitBlt function uses.
Win32, x64.
