C++ (Cpp) bitmapFile Examples

Example #1

File: SplashContainer.cpp Project: Tumunu/Mauru

// member functions
void CSplashContainer::ConstructL(const TRect &aRect)
{
  iBitmap = new(ELeave)CFbsBitmap();

  CreateWindowL();

  SetRect(aRect);
  SetExtentToWholeScreen();

  TFileName bitmapFile(KDrawBitmapPath);
  User::LeaveIfError(CompleteWithAppPath(bitmapFile));

  iLogoBitmap = new(ELeave)CFbsBitmap();
  User::LeaveIfError(iLogoBitmap->Load(bitmapFile, EMbmMauruSplash));

  ActivateL();
}

Example #2

File: CDXGraph.cpp Project: niepp/sperm-x

bool CDXGraph::SnapshotBitmap(const char * outFile)
{
	if (mBasicVideo)
	{
		long bitmapSize = 0;
		if (SUCCEEDED(mBasicVideo->GetCurrentImage(&bitmapSize, 0)))
		{
			bool pass = false;
			unsigned char * buffer = new unsigned char[bitmapSize];
			if (SUCCEEDED(mBasicVideo->GetCurrentImage(&bitmapSize, (long *)buffer)))
			{
				BITMAPFILEHEADER	hdr;
				LPBITMAPINFOHEADER	lpbi;

				lpbi = (LPBITMAPINFOHEADER)buffer;

				int nColors = 1 << lpbi->biBitCount;
				if (nColors > 256)
					nColors = 0;

				hdr.bfType		= ((WORD) ('M' << 8) | 'B');	//always is "BM"
				hdr.bfSize		= bitmapSize + sizeof( hdr );
				hdr.bfReserved1 	= 0;
				hdr.bfReserved2 	= 0;
				hdr.bfOffBits		= (DWORD) (sizeof(BITMAPFILEHEADER) + lpbi->biSize +
						nColors * sizeof(RGBQUAD));
