Bitmap上DrawString如何做到不模糊

Question

创建一张bitmap,并用DrawString() 上写数字；
把bitmap放到PictureBox里，
再把PictureBox放到Panel上，
显示出来的数字非常模糊图片放到PictureBox中没有任何拉升缩放，
PictureBox放到Panel上没有任何拉升缩放，请问这个数字在bitmap上怎么画才能不模糊？

Answer 1

测不出哪里拉升了。什么情况
                scale = new PictureBox();
                scale.BorderStyle = BorderStyle.None;
                scale.Width = Width;
                scale.Height = Height;
                scale.Parent = MainPanel;                bitmap = new Bitmap(Width , Height);
             //   Graphics g = MainPanel.CreateGraphics();
                Graphics g = Graphics.FromImage(bitmap);
                Pen pen = new Pen(Color.Black);
                pen.DashStyle = DashStyle.Solid;
                SolidBrush brush = new SolidBrush(Color.Black);
                Font font = new Font("Airal", 5);
                Point start = new Point(0, 0);                  //每个刻度断线的起终位置
                Point end = new Point(0, 0);
                if (0 == dir)   //水平
                {
                    g.DrawLine(pen, new Point(location.X, location.Y + Height - 1), new Point(location.X + Width, location.Y + Height - 1));
                    
                    start.X = location.X;
                    start.Y = location.Y + Height - 1;
                    //画短竖线
                    for (int i = 0; i <= WidthMM; i++)
                    {
                        start.X = location.X + CONVERT.MMToPiexls(i, _dpix);
                        start.Y = location.Y + Height - 1;                        end.X = start.X;
                        end.Y = start.Y - 3;
                        if (i % 5 == 0)
                        {
                            end.Y = start.Y - 4;
                        }
                        if (i % 10 == 0)
                        {
                            countX++;
                            end.Y = start.Y - 6;
                            StringFormat sf = new StringFormat();
                            //这里画出的数字很模糊
                            g.DrawString(i.ToString(), font, brush, new Point(start.X - 1, start.Y - 14));
                        }
                        g.DrawLine(pen, start, end);
                    }
                }                scale.Image = (Image)bitmap;
                g.Dispose();

Answer 2

我也碰到这个问题，8号字体就模糊。9号就OK了。
还有一个奇怪的事情。另外一个XP机器，显示正常是。现在是WIN7的就不正常。如果用Arial字本，不正常机器用9号10号也是不正常。
