Font Problem
-
Hi all, Iam using Keith Rule's CMemDc class & I have changed it according to my requirement.Iam posting that class also here. Now Iam zooming my View using "SetWorldTransform" call. My problem now is when I change the zoom factor to below or above 100,the Fonts are not smooth. The following are my codes: //Creating Font like this in "MyView" constructor.Don't want to use FixedFonts. m_oFont.CreatePointFont(120, _T("Courier New")); LOGFONT oLogfont; m_oFont.GetLogFont(&oLogfont); //OnPrepareDc looks like this. void MyView::OnPrepareDC(CDC* pDC, CPrintInfo* pInfo) { pDC->SetMapMode(MM_TEXT); SetGraphicsMode(pDC->GetSafeHdc(), GM_ADVANCED); pDC->SelectObject(&m_oFont); pDC->GetTextMetrics(&m_TextMetrics); XFORM xForm; xForm.eM11 = 0.01 * m_iZoomFactor; xForm.eM21 = 0; xForm.eDx = 0; xForm.eM12 = 0; xForm.eM22 = 0.01 * m_iZoomFactor; xForm.eDy = 0; pDC->GetTextMetrics(&m_textMetrics); SetWorldTransform(pDC->GetSafeHdc(), &xForm); CScrollView::OnPrepareDC(pDC, pInfo); } //My "OnDraw" looks like this. void MyView::OnDraw(CDC* pDC) { CpagesDoc* pDoc = GetDocument(); CSize sizeTotal; //default scrollsizes to 80 chars X 80 lines. sizeTotal.cx = 80; sizeTotal.cy = 80; //Client Rectangle Size. CRect rect; GetClientRect(&rect); //Creating a temporary Dc. C_TempDc tempDC(pDC,m_oFont,&rect); int pageWidth = 800; int pageHeight = 800; //int pageGap = 5; int pageNumber =3; SIZE size; size.cx = 1000; size.cy = (pageHeight*3)+100; //First Page tempDC->Rectangle(CRect(0,0,pageWidth,pageHeight)); tempDC->TextOut(5,10,"This is the first line on the FirstPage"); sizeTotal.cx *= MulDiv(m_textMetrics.tmAveCharWidth, m_iZoomFactor, 100); sizeTotal.cy *= MulDiv(m_textMetrics.tmHeight, m_iZoomFactor, 100); SetScrollSizes(MM_TEXT, sizeTotal); } //Keith Rule's Memory Buffer #ifndef C_TEMPDC_H #define C_TEMPDC_H class C_TempDc : public CDC { public: C_TempDc(CDC* pDC,CFont & font,const CRect* pRect = NULL): CDC() { ASSERT(pDC != NULL); //Initialising. m_pDC = pDC; m_oldBitmap = NULL; m_oldFont= NULL; //Getting ClipBox Rectangle. pDC->GetClipBox(&m_clipRect); //Client Rectangle. m_clientRect = *pRect; pDC->DPtoLP(&m_clientRect); // Create a Memory DC CreateCompatibleDC(pDC); //pDC->LPtoDP(&m_rect); m_bitmap.CreateCompatibleBitmap(pDC,m_clientRect.Width(),m_clientRect.Height()); pDC->LPtoDP(&m_clientRect); m_oldBitmap = SelectObject(&m_bitmap); ///Selecting the Font. m_oldFont = SelectObject(&f
