- // function is necessary for you to Blit an arbitrary bitmap (which may
- // have the wrong depth). wxDC::SelectObject will compare the depth of the
- // bitmap with the DC's depth, and create a new bitmap if the depths
- // differ. Eventually we should perhaps make this a public API function so
- // that an app can efficiently produce bitmaps of the correct depth. The
- // Windows solution is to use SetDibBits to blit an arbotrary DIB directly
- // to a DC, but this is too Windows-specific, hence this solution of
- // quietly converting the wxBitmap. Contributed by Frederic Villeneuve
