VC中特殊字体的实现(转)

渐变字：

// 获得窗口的客户区设备上下文句柄

       CClientDC dc(this);

       // 更改当前字体

       LOGFONT lf;

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

       CFont font, *pOldFont;

       lf.lfCharSet=134;

       lf.lfHeight=-150;

       lf.lfWidth=0;

       strcpy(lf.lfFaceName, "隶书");

       font.CreateFontIndirect(&lf);

       pOldFont=dc.SelectObject(&font);

       dc.SetBkMode(TRANSPARENT);

       // 更改当前画笔为空

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

       pOldPen=dc.SelectObject(&pen);

       // 更改当前刷子

       CBrush br, *pOldBrush;

       pOldBrush=dc.SelectObject(&br);

       // 开始一个路径

       dc.BeginPath();

       dc.TextOut(10, 10, "渐变字");

       dc.EndPath();

       // 绘制渐变效果

       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);

       }

       // 恢复设备上下文的原有设置

       dc.SelectObject(pOldFont);

       dc.SelectObject(pOldPen);

       dc.SelectObject(pOldBrush);

空心字：

// 获得窗口的客户区设备上下文句柄

       CClientDC dc(this);

       // 更改当前字体

       LOGFONT lf;

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

       CFont font;

       CFont *pOldFont; // 保存设备上下文最初使用的字体对象

       lf.lfCharSet=134;

       lf.lfHeight=-150;

       lf.lfWidth=0;

       strcpy(lf.lfFaceName, "隶书");

       font.CreateFontIndirect(&lf);

       pOldFont=dc.SelectObject(&font);

       dc.SetBkMode(TRANSPARENT);

       // 更改当前画笔

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

       CPen *pOldPen;

       pOldPen=dc.SelectObject(&pen);

       // 开始一个路径

       dc.BeginPath();

       dc.TextOut(10, 130, "空心字");

       dc.EndPath();

       // 绘制路径

       dc.StrokePath();

       // 恢复设备上下文的原有设置

       dc.SelectObject(pOldFont);

       dc.SelectObject(pOldPen);

立体字：在实现3D文字时一般不使用缺省的字体设置，而是通过对字体的设置而使产生的3D文字在视觉上更美观

       // 获得窗口的客户区设备上下文句柄      

       CClientDC dc(this);

       //定义字体属性

       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,"幼圆");

       //创建字体

       CFont font;

       font.CreateFontIndirect(&lf);

       //更改当前字体

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

       //绘制字体

       dc.SetBkMode(TRANSPARENT);

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

       dc.TextOut(10,10,"立体字");

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

       dc.TextOut(13,7,"立体字");

       //恢复设备上下文的原有设置

       dc.SelectObject(pOldFont);

旋转字：通过设置字体与X轴的倾斜角度（十分之一度为一个单位）

// 获得窗口的客户区设备上下文句柄      

       CClientDC dc(this);

       //定义字体属性

       LOGFONT lf;

       lf.lfHeight = 50;

       lf.lfWidth = 0;

       lf.lfEscapement = 300; //倾斜30度，十分之一度为单位

       lf.lfOrientation = 0;

       lf.lfWeight = FW_HEAVY;

       lf.lfItalic = FALSE;

       lf.lfUnderline = FALSE;

       lf.lfStrikeOut = FALSE;

       lf.lfCharSet = GB2312_CHARSET;

       strcpy(lf.lfFaceName,"幼圆");

       //创建字体

       CFont font;

       font.CreateFontIndirect(&lf);

       //更改当前字体

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

       //绘制字体

       dc.SetBkMode(TRANSPARENT);

       dc.SetTextColor(RGB(255,0,0));

       dc.TextOut(10,300,"旋转的字体");

       //恢复设备上下文的原有设置

       dc.SelectObject(pOldFont);
