This example draws backward text in a PictureBox. You could use similar techniques to draw backward text on a form, printout, bitmap file, or other drawing surface.

When the program starts, the following code executes. It draws the text into a Bitmap and then displays the Bitmap in the PictureBox.

private void Form1_Load(object sender, EventArgs e)
{
    Bitmap bm = new Bitmap(280, 100);
    using (Graphics gr = Graphics.FromImage(bm))
    {
        gr.TextRenderingHint =
            System.Drawing.Text.TextRenderingHint.AntiAliasGridFit;
        gr.ScaleTransform(-1, 1);
        using (Font the_font = new Font("Comic Sans MS", 40))
        {
            gr.DrawString("Backward", the_font, Brushes.Black, -280, 0);
            picBackward.Image = bm;
        }
    }
}

The code first makes a Bitmap big enough to hold the text. It then creates a Graphics object associated with the Bitmap.

Next the program sets the Graphic object's TextRenderingHint. The value AntiAliasGridFit makes drawn text come out smoothly anti-aliased so it isn’t jagged.

The program next applies a scale transform to the Graphics object that scales all graphics by a factor of -1 horizontally, making the result appear backward.

The program then creates a Font and calls the Graphics object’s DrawString method to draw the text. The code starts the text at position (-280, 0). The scale transform reverses the X coordinates of the text so the word “Backward” actually starts at position (280, 0) and draws to the left.

The program finishes by displaying the Bitmap in the PictureBox.

Tip: To make the PictureBox display the Bitmap at its full size, I set the PictureBox's SizeMode property to AutoSize at design time.
