[vtkusers] create bitmap

[cspl]

dear friends,

I am working on vtkWin32ImageMapper class to create hbitmap.But in that createBitmapObject function getting abort.Please give me suggestion where I am going wrong.I have written code as follows.

{


 LPBITMAPINFO lpbi;


 // Fill in the BITMAPINFOHEADER
 lpbi = (LPBITMAPINFO) new BYTE[sizeof(BITMAPINFOHEADER) + (256 * sizeof(RGBQUAD))];
 lpbi->bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
 lpbi->bmiHeader.biWidth = 512;//size.cx;
 lpbi->bmiHeader.biHeight = 512;//size.cy;
 lpbi->bmiHeader.biPlanes = 1;
 lpbi->bmiHeader.biBitCount = 8;
 lpbi->bmiHeader.biCompression = BI_RGB;
 lpbi->bmiHeader.biSizeImage = 512*512*8;//WIDTHBYTES((DWORD)size.cx * 8) * size.cy;
 lpbi->bmiHeader.biXPelsPerMeter = 0;
 lpbi->bmiHeader.biYPelsPerMeter = 0;
 lpbi->bmiHeader.biClrUsed = 0;
 lpbi->bmiHeader.biClrImportant = 0;
 for(int col=0;col<256;col++)
 {
  //int color=rand()%255;
  lpbi->bmiColors[col].rgbBlue=(BYTE)(col);
  lpbi->bmiColors[col].rgbGreen=(BYTE)(col);
  lpbi->bmiColors[col].rgbRed =(BYTE)(col);
  lpbi->bmiColors[col].rgbReserved=0;

 }

 LPLOGPALETTE lpLogPal;
 lpLogPal = (LPLOGPALETTE) new BYTE[sizeof(LOGPALETTE) + ((255) * sizeof(PALETTEENTRY))];
 lpLogPal->palVersion = 0x0300;
 lpLogPal->palNumEntries =256;
 
 for (int i = 0; i < 256; i++)
 {
  lpLogPal->palPalEntry[i].peRed = lpbi->bmiColors[i].rgbRed;
  lpLogPal->palPalEntry[i].peGreen = lpbi->bmiColors[i].rgbGreen;
  lpLogPal->palPalEntry[i].peBlue = lpbi->bmiColors[i].rgbBlue;
  lpLogPal->palPalEntry[i].peFlags = 0;
 }
 
 HDC hMemDC;
 hMemDC = CreateCompatibleDC(dc.m_hDC);

 CPalette m_Palette;
 VERIFY( m_Palette.CreatePalette( lpLogPal ) );

 
 HPALETTE m_hPalette=CreateHalftonePalette(hMemDC); 
 ::SelectPalette(dc.m_hDC,m_hPalette,FALSE ); 
 
 BYTE *pBits;

 HBITMAP oldbmp=NULL;
 unsigned char *data;

 vtkImageReader *Reader = vtkImageReader::New();
 Reader->SetDataByteOrderToLittleEndian();
 Reader->SetDataExtent(0,511,0,511,1,1);
 Reader->SetFileName(filepath);//"g:\\1.2.840.113713.10001.1.20076558.428.1013450393.36");
 Reader->SetDataSpacing(1.0, 1.0, 1.0);
 Reader->SetDataMask(0x7fff);
 Reader->SetDataScalarTypeToUnsignedShort(); 


 vtkWin32ImageMapper *bb=vtkWin32ImageMapper::New();
 HBITMAP  hBitmap1=bb->CreateBitmapObject(oldbmp,*lpbi,dc.m_hDC,data,Reader->GetOutput(),512,512);
}


Thanking you,
regards,
Satyanarayana
