How to paint a bold text and normal text

Question

Please help me to make bold some characters in sentence by using Graphics object. Thanks.

Example: I want to make bold on "example" word:
This is an example text.

Please remember to keep the spacing between characters.

Answer 1

Graphics.DrawString("SampleText", new Font("Arial", 80, FontStyle.Bold), Brushes.Black, 150, 125);

Hi,

You can specify bold for font style when you initialize font object by passing fontstyle parameter before you call the method of DrawString of Graphics to draw a text on form.

System.Drawing.Font drawFont = new System.Drawing.Font("Arial", 16, FontStyle.Bold );

Answer 4

Something like this should do what you're after:

private void Form1_Paint(object sender, PaintEventArgs e)
{
    using (Font normal = new Font("Tahoma", 10, FontStyle.Regular))
    using (Font bold = new Font("Tahoma", 10, FontStyle.Bold))
    using (StringFormat format = (StringFormat)StringFormat.GenericTypographic.Clone())
    {
        format.FormatFlags |= StringFormatFlags.MeasureTrailingSpaces;

        Rectangle temp = ClientRectangle;
        SizeF size = e.Graphics.MeasureString("This is an ", normal, temp.Width, format);
        e.Graphics.DrawString("This is an ", normal, SystemBrushes.WindowText, temp, format);
        temp.X += (int)size.Width;

        size = e.Graphics.MeasureString("example ", bold, temp.Width, format);
        e.Graphics.DrawString("example ", bold, SystemBrushes.WindowText, temp, format);
        temp.X += (int)size.Width;

        e.Graphics.DrawString("text.", normal, SystemBrushes.WindowText, temp, format);
    }
}

Answer 5

Please test your code with the following text:
This is anexampletext.

I see it has a remaining space after "example".

Answer 6

Sorry, it worked for me, but I forgot MeasureString will not produce the expected results given some settings, this code should work regardless (at least, it does for me on Windows 7 and XP):

private void Form1_Paint(object sender, PaintEventArgs e)
{
    using (Font normal = new Font("Tahoma", 10, FontStyle.Regular))
    using (Font bold = new Font("Tahoma", 10, FontStyle.Bold))
    using (StringFormat format = 
        (StringFormat)StringFormat.GenericTypographic.Clone())
    {
        format.FormatFlags |= StringFormatFlags.MeasureTrailingSpaces;
        Rectangle temp = ClientRectangle;

        DrawString(e.Graphics, SystemBrushes.WindowText, ref temp, format, 
            "This is an ", normal);
        DrawString(e.Graphics, SystemBrushes.WindowText, ref temp, format, 
            "example ", bold);
        DrawString(e.Graphics, SystemBrushes.WindowText, ref temp, format, 
            "string.", normal);
    }
}

void DrawString(Graphics g, Brush brush, ref Rectangle rect, 
    StringFormat format, string text, Font font)
{
    using (StringFormat copy = (StringFormat)format.Clone())
    {
        copy.SetMeasurableCharacterRanges(new CharacterRange[] {
        new CharacterRange(0, text.Length)});
        Region[] regions = g.MeasureCharacterRanges(text, font, rect, copy);

        g.DrawString(text, font, brush, rect, format);

        int width = (int)(regions[0].GetBounds(g).Width);
        rect.X += width;
        rect.Width -= width;
    }
}
