if(IDOK==dlg.DoModal())filename.Format("%s",dlg.GetPathName()); CDib.LoadFile(filename);}对显示原图菜单在view类下建立类向导，添加如下代码：voidCWork1View::OnYuantu(){ //TODO:Addyourcommandhandlercodehere CWork1Doc*pDoc=GetDocument();ASSERT_VALID(pDoc); filename=pDoc->filename; state1=1; Invalidate();}并在view类ondraw()函数中添加代码：if(state1==1) { CBitmapm_bitmap; HBITMAPhBitmap=(HBITMAP)LoadImage(NULL,_T(filename),IMAGE_BITMAP, 0,0,LR_CREATEDIBSECTION|LR_DEFAULTSIZE|LR_LOADFROMFILE);m_bitmap.Attach(hBitmap); CDCdcImage; if(!dcImage.CreateCompatibleDC(pDC)) return; BITMAPbm; m_bitmap.GetBitmap(&bm);dcImage.SelectObject(&m_bitmap); pDC->BitBlt(0,0,bm.bmWidth,bm.bmHeight,&dcImage,0,0,SRCCOPY); }之后添加类成员变量：Doc类添加：CStringfilename;CDibCDib;View类添加：CStringfilename;intstate1;Dib.h添加：#include"windowsx.h"这样就可以进行打开位图的操作。题目要求在右视图进行消息响应，则首先切分窗口并在该窗口显示位图，操作如下：添加CDynSplitterWnd的对象CSplitterWnd，并在mainfrm.h加入成员函数：CDynSplitterWndm_wndSplitter；以及头文件#include"DynSplitterWnd.h"增加新类用于与静态切分窗口相关联：CDynSplitterVIew2，基于CView类为CMainFrame增加OnCreateClient()函数重载，增加代码如下：BOOLCMainFrame::OnCreateClient(LPCREATESTRUCTlpcs,CCreateContext*pContext){ //TODO:Addyourspecializedcodehereand/orcallthebaseclass if(!m_wndSplitter.CreateStatic(this,1,2)) { TRACE0("FailedtoSplitterwindow\n"); returnFALSE; } //addthefirstsplitterpane-thedefaultviewincolumn0 if(!m_wndSplitter.CreateView(0,0, pContext->m_pNewViewClass,CSize(275,150),pContext)) { TRACE0("Failedtocreatefirstpane\n"); returnFALSE; } //addthesecondsplitterpane-aninputviewincolumn1 if(!m_wndSplitter.CreateView(0,1, RUNTIME_CLASS(CDynSplitterView2),CSize(0,0),pContext)) { TRACE0("Failedtocreatesecondpane\n"); returnFALSE; } //activatetheinputview SetActiveView((CView*)m_wndSplitter.GetPane(0,1)); returnTRUE;}添加一个新的函数TeXiaoXianShi()与CSplitterView2进行连接：增加成员变量：public:CPalette*CreateBitmapPalette(TeXiaoXianShiDib*pBitmap); CStringfilename; TeXiaoXianShiDib*CDibNew1; CDib*CDib1; CPalettehPalette; intstate2; voidclearmem();//Operationspublic:CWork2Doc*GetDocument();增加函数：CWork2Doc*CDynSplitterView2::GetDocument()//non-debugversionisinline{ ASSERT(m_pDocument->IsKindOf(RUNTIME_CLASS(CWork2Doc))); return(CWork2Doc*)m_pDocument;}voidCDynSplitterView2::clearmem(){ CWork2Doc*pDoc=GetDocument(); ASSERT_VALID(pDoc); pDoc->statedoc=0;state2=1; CDibNew1=&pDoc->CDibNew;CDib1=&pDoc->CDib; longintsize=CDib1->GetHeight()*CDib1->GetWidth(); memcpy(CDibNew1->m_pData,CDib1->m_pData,size);//复制原图像到处理区}CPalette*CDynSplitterView2::CreateBitmapPalette(TeXiaoXianShiDib*pBitmap) { struct { WORDVersion; WORDNumberOfEntries; PALETTEENTRYaEntries[256]; }palette={0x300,256}; LPRGBQUADpRGBTable=pBitmap->GetRGB(); UINTnumberOfColors=pBitmap->GetNumberOfColors(); for(UINTx=0;x<numberOfColors;++x) { palette.aEntries[x].peRed= pRGBTable[x].rgbRed; palette.aEntries[x].peGreen= pRGBTable[x].rgbGreen; palette.aEntries[x].peBlue= pRGBTable[x].rgbBlue; palette.aEntries[x].peFlags=0; } hPalette.CreatePalette((LPLOGPALETTE)&palette); //CPalettehPale=&hPalette; return&hPalette; }之后修改ondraw()函数：voidCDynSplitterView2::OnDraw(CDC*pDC){ CWork2Doc*pDoc=GetDocument(); ASSERT_VALID(pDoc); if(!pDoc->statedoc&&state2==1) {BYTE*pBitmapData=CDibNew1->GetData();LPBITMAPINFOpBitmapInfo=CDibNew1->GetInfo();intbitmapHeight=CDibNew1->GetHeight();intbitmapWidth=CDibNew1->GetWidth(); intscaledWidth=(int)(bitmapWidth*1); intscaledHeight=(int)(bitmapHeight*1); if(CDibNew1->GetRGB())//Hasacolortable { CPalette*hPalette1=CreateBitmapPalette(CDibNew1);CPalette*hOldPalette=pDC->SelectPalette(hPalette1,true);pDC->RealizePalette(); ::StretchDIBits(pDC->GetSafeHdc(),0,0,bitmapWidth,bitmapHeight, 0,0,bitmapWidth,bitmapHeight, pBitmapData,pBitmapInfo, DIB_RGB_COLORS,SRCCOPY);pDC->SelectPalette(hOldPalette,true);hPalette.DeleteObject(); } else {::StretchDIBits(pDC->GetSafeHdc(),0,0,scaledWidth,scaledHeight,0,0,bitmapWidth,bitmapHeight, pBitmapData,pBitmapInfo, DIB_RGB_COLORS,SRCCOPY); } } //TODO:adddrawcodehere}这样就可以在切分窗口进行消息关联图像颜色修改关键代码：（将蓝色像素点变为绿色）voidCDynSplitView2::OnXiugai(){ //TODO:Addyourcommandhandlercodehere CDC*pDC=GetDC(); CRectrect(0,0,1000,1000); CBrushbrush(RGB(255,255,255)); pDC->FillRect(&rect,&brush); //复制图像数据 clearmem(); CDSplitDoc*pDoc=GetDocument(); ASSERT_VALID(pDoc); if(!pDoc->statedoc&&state2==1) {BYTE*pBitmapData=CDibNew1->GetData();LPBITMAPINFOpBitmapInfo=CDibNew1->GetInfo();intbitmapHeight=CDibNew1->GetHeight();intbitmapWidth=CDibNew1->GetWidth();

deletetemp; }}红气球复制关键代码：voidCDynSplitView2::OnCopy(){ //TODO:Addyourcommandhandlercodehere inti,j; CDC*pDC=GetDC(); CRectrect(0,0,1000,1000); CBrushbrush(RGB(255,255,255)); pDC->FillRect(&rect,&brush);
