C#DrawString 怎么设置字间距和行间距

1、设置Image对象：System.Drawing.Image img = System.Drawing.Image.FromFile("c:\\bg.png");

2、将img赋值给Graphics：Graphics g = Graphics.FromImage(img);

3、设置图像Graphics g的杨钭维程属性： //设置高质量插值法 g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.High; //设置高质量,低速度呈现平滑程度 g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality; g.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality; //消除锯齿 g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;

4、设置字体和笔刷：Font f12 = new Font("微软雅黑", 12, FontStyle.Regular);SolidBrush bru = new SolidBrush(Color.White);

5、设置PointF和SizeF:PointF pf = new Point(10, 10);SizeF charSize;

6、将需要操作的字符串转为char[]:string 待写入字符串 = "待写入字符串"; char[] ch = 待写入字符串.ToCharArray();

7、这是两个变量：行高和亨蚂擤缚字间距，并将转换为char[]的字符逐一写入图片中。以下是核心代码：foreach (char c in ch) { //获取字符尺寸 charSize = g.MeasureString(c.ToString(), f12); //逐一写入字符 g.DrawString(c.ToString(), f12, bru, pf); //设置字间距 pf.X += (charSize.Width - 字间距); //设置行高 if (pf.X > 1000) { pf.X = 10; pf.Y += (charSize.Height + 5); } }
