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);
