VC中特殊字體的實現(轉)

漸變字：<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

// 獲得窗口的客戶區設備上下文句柄

       CClientDC dc(this);

       // 更改當前字體

       LOGFONT lf;

       dc.GetCurrentFont()->GetLogFont(&lf);

       CFont font, *pOldFont;

       lf.lfCharSet=134;

       lf.lfHeight=-150;

       lf.lfWidth=0;

       strcpy(lf.lfFaceName, "隸書");

       font.CreateFontIndirect(&lf);

       pOldFont=dc.SelectObject(&font);

       dc.SetBkMode(TRANSPARENT);

       // 更改當前畫筆爲空

       CPen pen(PS_NULL, 1, RGB(255, 0, 0)), *pOldPen;

       pOldPen=dc.SelectObject(&pen);

       // 更改當前刷子

       CBrush br, *pOldBrush;

       pOldBrush=dc.SelectObject(&br);

       // 開始一個路徑

       dc.BeginPath();

       dc.TextOut(10, 10, "漸變字");

       dc.EndPath();

       // 繪製漸變效果

       dc.SelectClipPath(RGN_COPY);

       for (int i=255; i>0; i--)

       {

              int iRadius=(600*i)/255;

              dc.SelectObject(pOldBrush);

              br.DeleteObject();

              br.CreateSolidBrush(RGB(255, i, 0));

              dc.SelectObject(&br);

              dc.Ellipse(-iRadius, -iRadius/3, iRadius, iRadius/3);

       }

       // 恢復設備上下文的原有設置

       dc.SelectObject(pOldFont);

       dc.SelectObject(pOldPen);

       dc.SelectObject(pOldBrush);

空心字：

// 獲得窗口的客戶區設備上下文句柄

       CClientDC dc(this);

       // 更改當前字體

       LOGFONT lf;

       dc.GetCurrentFont()->GetLogFont(&lf);

       CFont font;

       CFont *pOldFont; // 保存設備上下文最初使用的字體對象

       lf.lfCharSet=134;

       lf.lfHeight=-150;

       lf.lfWidth=0;

       strcpy(lf.lfFaceName, "隸書");

       font.CreateFontIndirect(&lf);

       pOldFont=dc.SelectObject(&font);

       dc.SetBkMode(TRANSPARENT);

       // 更改當前畫筆

       CPen pen(PS_SOLID, 1, RGB(255, 0, 0));

       CPen *pOldPen;

       pOldPen=dc.SelectObject(&pen);

       // 開始一個路徑

       dc.BeginPath();

       dc.TextOut(10, 130, "空心字");

       dc.EndPath();

       // 繪製路徑

       dc.StrokePath();

       // 恢復設備上下文的原有設置

       dc.SelectObject(pOldFont);

       dc.SelectObject(pOldPen);

立體字：在實現3D文字時一般不使用缺省的字體設置，而是通過對字體的設置而使產生的3D文字在視覺上更美觀

       // 獲得窗口的客戶區設備上下文句柄      

       CClientDC dc(this);

       //定義字體屬性

       LOGFONT lf;

       lf.lfHeight = 50;    

       lf.lfWidth = 0;

       lf.lfEscapement = 0;

       lf.lfOrientation = 0;

       lf.lfWeight = FW_HEAVY;

       lf.lfItalic = FALSE;

       lf.lfUnderline = FALSE;

       lf.lfStrikeOut = FALSE;

       lf.lfCharSet = GB2312_CHARSET;

       strcpy(lf.lfFaceName,"幼圓");

       //創建字體

       CFont font;

       font.CreateFontIndirect(&lf);

       //更改當前字體

       CFont *pOldFont  = dc.SelectObject(&font);

       //繪製字體

       dc.SetBkMode(TRANSPARENT);

       dc.SetTextColor(::GetSysColor(COLOR_3DDKSHADOW));

       dc.TextOut(10,10,"立體字");

       dc.SetTextColor(::GetSysColor(COLOR_3DHILIGHT));

       dc.TextOut(13,7,"立體字");

       //恢復設備上下文的原有設置

       dc.SelectObject(pOldFont);

旋轉字：通過設置字體與X軸的傾斜角度（十分之一度爲一個單位）

// 獲得窗口的客戶區設備上下文句柄      

       CClientDC dc(this);

       //定義字體屬性

       LOGFONT lf;

       lf.lfHeight = 50;

       lf.lfWidth = 0;

       lf.lfEscapement = 300; //傾斜30度，十分之一度爲單位

       lf.lfOrientation = 0;

       lf.lfWeight = FW_HEAVY;

       lf.lfItalic = FALSE;

       lf.lfUnderline = FALSE;

       lf.lfStrikeOut = FALSE;

       lf.lfCharSet = GB2312_CHARSET;

       strcpy(lf.lfFaceName,"幼圓");

       //創建字體

       CFont font;

       font.CreateFontIndirect(&lf);

       //更改當前字體

       CFont *pOldFont  = dc.SelectObject(&font);

       //繪製字體

       dc.SetBkMode(TRANSPARENT);

       dc.SetTextColor(RGB(255,0,0));

       dc.TextOut(10,300,"旋轉的字體");

       //恢復設備上下文的原有設置

       dc.SelectObject(pOldFont);
