VC ++和C#中的字体区别是什么 [英] What is font difference in VC++ and C#

问题描述

我使用C#绘制简单文本

I draw simple text using C#

private void Form1_Paint(object sender, PaintEventArgs e)
        {
            System.Drawing.Rectangle pRect = new Rectangle(126, 35, 182, 59);

            StringFormat objStrFormat = new StringFormat();
            objStrFormat.Alignment = StringAlignment.Center;
            objStrFormat.LineAlignment = StringAlignment.Center;        
            
            e.Graphics.DrawRectangle(Pens.Black, pRect);
            e.Graphics.FillRectangle(new SolidBrush(Color.DarkOrange), pRect);

            Font pLOGFONT = new Font("Arial", 20, FontStyle.Bold);
            
            e.Graphics.DrawString("Sample Text", pLOGFONT, new SolidBrush(Color.Black), pRect, objStrFormat);
            
        }

与上面使用MFC的代码相同

Same as above code using MFC

CBrush* OldBrush;
	CFont* OldFont=NULL;
	CPen *OldPen=NULL;
	CPen BClrPen;
	CBrush BgBrush;
	CFont m_TextFont;

	CClientDC dc(this);

	COLORREF rgb(RGB(0,0,0));
	BClrPen.CreatePen(PS_SOLID,1,rgb);
	OldPen=dc.SelectObject(&BClrPen);

	BgBrush.CreateSolidBrush(RGB(123,150,0));

	OldBrush=dc.SelectObject(&BgBrush);
	dc.Rectangle(126,35,308,94);	
	dc.SelectObject(OldBrush);
	dc.SelectObject(OldPen);
	BClrPen.DeleteObject();	
	
	memset(&lf,0,sizeof(LOGFONT));	
	
	lf.lfHeight = 31;
	lf.lfWidth =  20;//Need to set 14.5

        lf.lfEscapement = 0;
	lf.lfOrientation = 0;
	lf.lfWeight = 700;
	lf.lfItalic = 0;
	lf.lfUnderline = 0;
	lf.lfStrikeOut = 0;
	lf.lfCharSet = 1;
	lf.lfOutPrecision = 0;
	lf.lfClipPrecision = 0;
	lf.lfQuality = 0;
	lf.lfPitchAndFamily = 0;
	lstrcpy(lf.lfFaceName, _T("Arial"));	

	m_TextFont.CreateFontIndirect(&lf);

dc.SetBkMode(TRANSPARENT);
	COLORREF m_cBgColor(RGB(50,20,100));
	dc.SetTextColor(m_cBgColor);
	OldFont = dc.SelectObject(&m_TextFont);
	dc.DrawText(_T("Sample Text"),11,CRect(126,35,308,94),DT_SINGLELINE | DT_CENTER | DT_VCENTER);			
	dc.SelectObject(OldFont);

在以上两种情况下，字体大小均设置为20，但在MFC中，字体看起来大于C#输出.唯一的区别是大小(宽度参数)在MFC中为逻辑像素，在C#中为Point.

那么，由于我在MFC中使用C#应用程序，如何将Point转换为逻辑像素或其他任何合适的方法?

In the above, in both cases the font size is set to 20 but in MFC font looks bigger than C# output. Got one difference is size (width parameter)is in logical pixel in MFC and Point in C#.

So how do I convert Point into logical pixel or any other suitable way because I am using C# application in MFC?

推荐答案

请确保字体规格相同

make sure that font metrics are same
