一、要把文本和图形保存到位图文件，只要对掌握位图结构有一定的了解，一切都ok呢。先必须要创建内存设备环境，然后内存设备环境创建的DIB区域，别忘了还要创建个CBitmap对象，CBitmap对象必须和DIB区域关联起来，把CBitmap对象选择到当前设备环境，然后在当前设备环境输出文本和图形就可以了。 二、具体实现代码如下 void CTestSaveBmpView::SaveAsBmp(CString filename){ //定义图形大小 int iWidth = 800; int iHeight = 600; int iPixel = 16;  //图形格式参数 LPBITMAPINFO lpbmih = new BITMAPINFO; lpbmih->bmiHeader.biSize = sizeof(BITMAPINFOHEADER); lpbmih->bmiHeader.biWidth = iWidth; lpbmih->bmiHeader.biHeight = iHeight; lpbmih->bmiHeader.biPlanes = 1; lpbmih->bmiHeader.biBitCount = iPixel; lpbmih->bmiHeader.biCompression = BI_RGB; lpbmih->bmiHeader.biSizeImage = 0; lpbmih->bmiHeader.biXPelsPerMeter = 0; lpbmih->bmiHeader.biYPelsPerMeter = 0; lpbmih->bmiHeader.biClrUsed = 0; lpbmih->bmiHeader.biClrImportant = 0;  //创建位图数据 HDC hdc,hdcMem; HBITMAP hBitMap = NULL; CBitmap *pBitMap = NULL; CDC *pMemDC = NULL; BYTE *pBits; hdc = CreateIC(TEXT("DISPLAY"),NULL,NULL,NULL); hdcMem = CreateCompatibleDC(hdc); hBitMap = CreateDIBSection(hdcMem,lpbmih,DIB_PAL_COLORS,(void **)&pBits,NULL,0); pBitMap = new CBitmap; pBitMap->Attach(hBitMap); pMemDC = new CDC; pMemDC->Attach(hdcMem); pMemDC->SelectObject(pBitMap);     //添加自绘图形  CRect rc(0,0,iWidth,iHeight); pMemDC->SetBkMode(TRANSPARENT); DrawCurve(pMemDC,rc);  //保存到文件并创建位图结构 BITMAPFILEHEADER bmfh; ZeroMemory(&bmfh,sizeof(BITMAPFILEHEADER)); *((char *)&bmfh.bfType) = ''B''; *(((char *)&bmfh.bfType) + 1) = ''M''; bmfh.bfOffBits = sizeof(BITMAPFILEHEADER) + sizeof(BITMAPINFOHEADER); bmfh.bfSize = bmfh.bfOffBits + (iWidth * iHeight) * iPixel / 8;  TCHAR szBMPFileName[128]; int iBMPBytes = iWidth * iHeight * iPixel / 8; strcpy(szBMPFileName,filename); CFile file; if(file.Open(szBMPFileName,CFile::modeWrite | CFile::modeCreate)) {  file.Write(&bmfh,sizeof(BITMAPFILEHEADER));  file.Write(&(lpbmih->bmiHeader),sizeof(BITMAPINFOHEADER));  file.Write(pBits,iBMPBytes);  file.Close(); }  pMemDC->DeleteDC(); delete pMemDC; pMemDC = NULL; delete pBitMap; pBitMap = NULL; delete lpbmih; lpbmih = NULL;}
