                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));
            }

I need to get

this is normal and this is bold text

But I receive overlay of second text on first

Answer 1

Try this code, might do the job.!!!

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));
}

Answer 2

I would recommend to use:

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