绘制粗体和普通文本

本文关键字：文本 绘制 | 更新日期: 2023-09-27 18:08:40

代码:

using (Graphics g = Graphics.FromImage(pictureBox1.Image))
            {
                Font drawFont = new Font("Arial", 12);
                Font drawFontBold = new Font("Arial", 12, FontStyle.Bold);
                SolidBrush drawBrush = new SolidBrush(Color.Black);
                g.DrawString("this is normal", drawFont, drawBrush, new RectangleF(350f, 250f, 647, 200));
                g.DrawString(" and this is bold text", drawFontBold, drawBrush, new RectangleF(350f, 250f, 647, 200));
            }

我需要得到

这是正常的，这是粗体文本

但是我收到了第二个文本在第一个

绘制粗体和普通文本

上的叠加

试试这段代码，可能会成功!!

using (Graphics g = Graphics.FromImage(pictureBox1.Image))
{
    Font drawFont = new Font("Arial", 12);
    Font drawFontBold = new Font("Arial", 12, FontStyle.Bold);
    SolidBrush drawBrush = new SolidBrush(Color.Black);
    // find the width of single char using selected fonts
    float CharWidth = g.MeasureString("Y", drawFont).Width;
    // draw first part of string
    g.DrawString("this is normal", drawFont, drawBrush, new RectangleF(350f, 250f, 647, 200));
    // now get the total width of words drawn using above settings
    float widthFirst = ("this is normal").Length() * CharWidth;
    // the width of first part string to start of second part to avoid overlay
    g.DrawString(" and this is bold text", drawFontBold, drawBrush, new RectangleF(350f + widthFirst, 250f, 647, 200));
}

我建议使用:

    float widthFirst = g.MeasureString("this is normal", drawFont).Width;
