  45 and a printer also has a device context. In this way, the same piece
 
  46 of code may write to a number of different devices, if the device
 
  47 context is used as a parameter.

1582         be flushed to this DC when this object is destroyed. You may
 
1583         pass ``None`` in order to just initialize the buffer, and not
 
1586     :param buffer: If a `wx.Size` object is passed as the 2nd arg then
 
1587         it is the size of the bitmap that will be created internally
 
1588         and used for an implicit buffer. If the 2nd arg is a
 
1589         `wx.Bitmap` then it is the explicit buffer that will be
 
1590         used. Using an explicit buffer is the most efficient solution
 
1591         as the bitmap doesn't have to be recreated each time but it
 
1592         also requires more memory as the bitmap is never freed. The
 
1593         bitmap should have appropriate size, anything drawn outside of
 
1594         its bounds is clipped.  If wx.NullBitmap is used then a new
 
1595         buffer will be allocated that is the same size as the dc.
 
1597     :param style: The style parameter indicates whether the supplied buffer is
 
1598         intended to cover the entire virtual size of a `wx.ScrolledWindow` or
 
1599         if it only covers the client area.  Acceptable values are
 
1600         ``wx.BUFFER_VIRTUAL_AREA`` and ``wx.BUFFER_CLIENT_AREA``.
