C++ (Cpp) wxBitmap::GetPalette Examples

Example #1

File: splash.cpp Project: BauerBox/wxWidgets

static void wxDrawSplashBitmap(wxDC& dc, const wxBitmap& bitmap, int WXUNUSED(x), int WXUNUSED(y))
{
    wxMemoryDC dcMem;

#ifdef USE_PALETTE_IN_SPLASH
    bool hiColour = (wxDisplayDepth() >= 16) ;

    if (bitmap.GetPalette() && !hiColour)
    {
        dcMem.SetPalette(* bitmap.GetPalette());
    }
#endif // USE_PALETTE_IN_SPLASH

    dcMem.SelectObjectAsSource(bitmap);
    dc.Blit(0, 0, bitmap.GetWidth(), bitmap.GetHeight(), &dcMem, 0, 0, wxCOPY,
            true /* use mask */);
    dcMem.SelectObject(wxNullBitmap);

#ifdef USE_PALETTE_IN_SPLASH
    if (bitmap.GetPalette() && !hiColour)
    {
        dcMem.SetPalette(wxNullPalette);
    }
#endif // USE_PALETTE_IN_SPLASH
}

Example #2

File: splash.cpp Project: EdgarTx/wx

    if (bitmap.GetPalette() && !hiColour)
    {

}

Example #3

File: bitmap.cpp Project: gitrider/wxsj2
