비트 맵으로 hBitmap을 저장할 때 일반 GDI + 오류

Question

나는 내 자신의 DIB/BMP 디코더를 작성하고 있습니다. 이미 다른 것들이 있지만, 이미지 처리에 대해 배우고 있습니다. 그리고 포인터를 픽셀에 저장하고 관리합니다. 관련 HBITMAP을 작성하기위한 차원 만이 오류가 온 유지 :

코드 :

public Bitmap BitmapFromPCXBits(int height, int width, int numplanes, int bpp, IntPtr pixels) 
    { 
     IntPtr hDc = CreateCompatibleDC(IntPtr.Zero); 
     IntPtr hBitmap = IntPtr.Zero; 
     IntPtr hOldBitmap = IntPtr.Zero; 

     hBitmap = CreateBitmap(width, height, (uint)numplanes, (uint)bpp, pixels); 
     hOldBitmap = SelectObject(hDc, hBitmap); 

     System.Drawing.Bitmap bmp = System.Drawing.Bitmap.FromHbitmap(hBitmap); 
     //Bitmap bmp = new Bitmap(width, height, stride, System.Drawing.Imaging.PixelFormat.Format1bppIndexed, pixels); 

     DeleteObject(SelectObject(hDc, hOldBitmap)); 

     DeleteDC(hDc); 

     return bmp; 
    }

Generic Error Occured in GDI+. 

는 스택 추적 및 코드입니다

나는 무엇이 잘못 되었는가 전혀 모르지만 PCX 파일에 대해 비슷한 기능을 사용하고 단색 이미지를 제외하고 모두 정상적으로 렌더링됩니다. 누구든지 도울 수 있다면, 나는 매우 감사하고있다.

그것은

어쨌든 몇 가지가 시도 ... 입력 당신은 당신의 전화에있는 parametes 모르고 얘기하기 어렵다 : CreateBitmap에서

• 체크 반환 값은()!
• 비트 평면의 수는

• 이

  을 (면의 수를 알고 있다면 당신은 매개 변수로 전달하지 않아도, 비트 맵 형식하여 GDI + 열거와) 대신에 비트 맵 생성자를 사용 권리 확인

  // C++에서 작동

  HDC hOff = :: CreateCompatibleDC (NULL);

  비트 맵 oDaBigOne (g_iWidth, g_iHeight, PixelFormat32bppARGB);

  HBITMAP hBMit = NULL;

  색상 oCol (0, 0, 0, 0);

  oDaBigOne.GetHBITMAP (oCol, &hBMit);

  HGDIOBJ hSave = :: SelectObject (hOff, hBMit);
