HBRUSH创建 a)实色填充
HBRUSH CreateSolidBrush( COLORREF color);b)栅格线填充
HBRUSH CreateHatchBrush( int iHatch, COLORREF color);c)平铺图填充
HBRUSH CreatePatternBrush( HBITMAP hbm);
HBITMAP hBitmap LoadBitmap(g_hInst, MAKEINTRESOURCE(IDB_LOGO));d)空填充可以创建前三种任何一种也可以创建第四种空中
HBRUSH CreateBrushIndirect( [in] const LOGBRUSH *plbrush);对应的CBrush
CBrush::CreateBrushIndirectInitializes a brush with the style, color, and pattern specified in a LOGBRUSH structure.CBrush::CreateDIBPatternBrushInitializes a brush with a pattern specified by a device-independent bitmap (DIB).CBrush::CreateHatchBrush //Initializes a brush with the specified hatched pattern and color.
CBrush::CreatePatternBrush //Initializes a brush with a pattern specified by a bitmap 图片
CBrush::CreateSolidBrush // Initializes a brush with the specified solid color. 实色
CBrush::CreateSysColorBrush // Creates a brush that is the default system color.CBrush::FromHandleReturns a pointer to a CBrush object when given a handle to a Windows HBRUSH object.CBrush::GetLogBrush // Gets a LOGBRUSH structure./* Hatch Styles */ 填充风格

CFont类的主要函数 a)CFont::CreateFont:参数太多没法用 b)使用结构体创建比较方便
BOOL CreateFontIndirect( const LOGFONT* lpLogFont );c)GetLogFont获取字体信息是以上函数的反函数。 d)简易创建函数他的大小是以上函数的十分之一所以调用时要乘以10。
CreateFont和CreateFontIndirect中间加Point。Requested font height in tenths of a point. (For instance, pass 120 to request a 12-point font.)typedef struct tagLOGFONT { LONG lfHeight; LONG lfWidth; LONG lfEscapement; //书写角度LONG lfOrientation; //基线角度LONG lfWeight; BYTE lfItalic; BYTE lfUnderline; BYTE lfStrikeOut; //删除线BYTE lfCharSet; //字符集表示 BYTE lfOutPrecision; //输出精度BYTE lfClipPrecision; //剪辑精度BYTE lfQuality; //字体质量BYTE lfPitchAndFamily; //字体的字符间距和族标识TCHAR lfFaceName[LF_FACESIZE]; //字体名称
} LOGFONT;CFont font;//font.CreatePointFont(100 * 3 / 2, _T(黑体)); //简易函数LOGFONT lf{ 15 * 3 / 2 };lf.lfItalic TRUE;lf.lfWeight 700;lf.lfCharSet GB2312_CHARSET;lf.lfEscapement 200;_tcscpy_s(lf.lfFaceName, LF_FACESIZE, _T(黑体));font.CreateFontIndirect(lf);auto pOldFont dc.SelectObject(font);//dc.SetBkMode(TRANSPARENT); //设置文字的透明色 //真透明 //dc.SetTextColor(0xff);dc.SetBkColor(0xffff00); //假透明dc.DrawText(_T(这世间本没有佛), rect, DT_CENTER|DT_VCENTER|DT_SINGLELINE);pOldFont-GetLogFont(lf);CPen类简介
CPen::CreatePen
Creates a logical cosmetic or geometric pen with the specified style, width,and brush attributes, and attaches it to the CPen object.CPen::CreatePenIndirectCreates a pen with the style, width, and color given in a LOGPEN structure,and attaches it to the CPen object.CPen::FromHandle //Returns a pointer to a CPen object when given a Windows HPEN.
CPen::GetExtLogPen //Gets an EXTLOGPEN underlying structure.
CPen::GetLogPen //Gets a LOGPEN underlying structure.
CPen::operator HPEN //Returns the Windows handle attached to the CPen object./* Pen Styles */
