You have posted us an error you are getting. We cannot provide you with a proper solution unless you tell us how you are invoking the method (button click)? See my answer below.

Telep: a rich text box
On a button click, I was taking the rich text box creating a bitmap, and then making it in the same location as telep, but above it. And then I finally made it mirrored horizontally.

C#

public void pictureBox6_Click(object sender, EventArgs e)
        {            
            //Create a PictureBox with the same location and size as the RichTextBox.
            PictureBox pic = new PictureBox();
            pic.Location = this.telep.Location;
            pic.Size = this.telep.Size;

            //Draw the richTextBox to a bitmap
            Bitmap bitmap = new Bitmap(this.telep.Width, this.telep.Height);
            DrawToBitmap(this.telep, bitmap, new Rectangle(Point.Empty, this.telep.Size));
            bitmap.RotateFlip(RotateFlipType.RotateNoneFlipX);

            //Set the image of the PictureBox to that image.
            pic.Image = bitmap;
            this.Controls.Add(pic);
            pic.BringToFront();

            pic.Dock = DockStyle.Fill;
        }

        private void DrawToBitmap(RichTextBox richTextBox, Bitmap image, Rectangle targetRectangle)
        {
            
            Graphics g = telep.CreateGraphics();
            Graphics g2 = Graphics.FromImage(image);
            IntPtr gi = g.GetHdc();
            IntPtr gi2 = g2.GetHdc();
            BitBlt(gi2, 0, 0, richTextBox.Width, richTextBox.Height, gi, 0, 0, 0x00CC0020);
            g.ReleaseHdc();
            g2.ReleaseHdc();
            g.Dispose();
            g2.Dispose();

        }

Hi,
If you have a byte array that represents a file that WPF can decode (bmp, jpg, gif, png, tif, ico), you can do the following

C#

BitmapSource LoadImage(Byte[] imageData)
{
    using (MemoryStream ms = new MemoryStream(imageData))
    {
        var decoder = BitmapDecoder.Create(ms,
            BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.OnLoad);
        return decoder.Frames[0];
    }
}
