【转】WinAPI: CreateFontIndirect

//声明:
CreateFontIndirect(
  const p1: TLogFont {字体结构}
): HFONT;            {返回新字体指针}

//TLogFont 是 tagLOGFONTA 结构的重定义:
tagLOGFONTA = packed record
  lfHeight: Longint;      {字体高度}
  lfWidth: Longint;       {字体平均宽度}
  lfEscapement: Longint;  {角度, 单位是 1/10 度}
  lfOrientation: Longint; {基线角度}
  lfWeight: Longint;      {粗体, 取值: 0-1000}
  lfItalic: Byte;         {斜体}
  lfUnderline: Byte;      {下划线}
  lfStrikeOut: Byte;      {删除线}
  lfCharSet: Byte;        {字符集}
  lfOutPrecision: Byte;   {输出精度}
  lfClipPrecision: Byte;  {剪裁精度}
  lfQuality: Byte;        {输出质量}
  lfPitchAndFamily: Byte; {间距及字族}
  lfFaceName: array[0..LF_FACESIZE - 1] of AnsiChar; {字样名称}
end;

以上是要用到的一个数据结构，unit windows.

使用方法详细：

  {定义字体特征}
  FontInfo.lfHeight := 0;     {赋值 0, 系统自动给一个值}
  FontInfo.lfWidth := 0;      {赋值 0, 系统自动给一个值}
  FontInfo.lfEscapement := 0; {无角度}
  FontInfo.lfWeight := 500;   {中等加粗}
  FontInfo.lfItalic := 0;     {非斜体}
  FontInfo.lfUnderline := 0;  {无下划线}
  FontInfo.lfStrikeOut := 0;  {无删除线}
  FontInfo.lfFaceName := '宋体';
  
  FH1 := CreateFontIndirect(FontInfo);
  FH2 := SelectObject(Canvas.Handle, FH1);
  {用 CreateFontIndirect 建立逻辑字体; 用 SelectObject 选人设备; 并返回字体句柄}
  
  TextOut(Canvas.Handle, X, Y, str, Length(str));
  
  DeleteObject(FH1);
  DeleteObject(FH2);

详细：万一的博客

想要循环的文字：改变属性Escapement，循环输出

注意点：

FH1 := CreateFontIndirect(FontInfo);
FH2 := SelectObject(Canvas.Handle, FH1);

这两个用完以后要及时删除！！

DeleteObject(FH1);
DeleteObject(FH2);
