Graphics.DrawString vs TextRenderer.DrawText?Which can Deliver Better Quality

Question

TextRenderer is based on GDI and Graphics.DrawString is based on GDI+.Which of these functions can deliver better quality text while drawing text on an image.

Answer 1

I'll just throw in some test code:

class Form1: Form
{
    private string str = "hello world hello world hello world";
    private int x = 32, yLabel = 0, yDraw = 64, yRenderer = 32;

    public Form1()
    {
        Font = new Font("Times", 16);

        Label label = new Label();
        label.BorderStyle = BorderStyle.FixedSingle;
        label.AutoSize = true;
        label.Text = str;
        label.Location = new Point(x, yLabel);
        Controls.Add(label);
    }

    protected override void OnPaint(PaintEventArgs e)
    {
        SizeF a;

        // TextRenderer
        a = TextRenderer.MeasureText(str, Font);
        TextRenderer.DrawText(e.Graphics, str, Font, new Point(x, yRenderer), Color.Pink);
        e.Graphics.DrawRectangle(new Pen(Color.Blue), x, yRenderer, a.Width, a.Height);

        // DrawString
        e.Graphics.DrawString(str, Font, new SolidBrush(Color.Red), x, yDraw);
        a = e.Graphics.MeasureString(str, Font);
        e.Graphics.DrawRectangle(new Pen(Color.Lime), x, yDraw, a.Width, a.Height);

        base.OnPaint(e);
    }
}

Bottom line: compared to a simple Label, TextRenderer is more accurate.
