Showing textbox text over image

Bitmap bitMapImage = new System.Drawing.Bitmap(Server.MapPath(path)); Graphics graphicImage = Graphics.FromImage(bitMapImage); graphicImage.DrawString(sendtotxt.Text, new Font("Arial", 12, FontStyle.Bold), SystemBrushes.WindowText, new Point(10, 10)); graphicImage.DrawString(sendfromtxt.Text, new Font("Arial", 12, FontStyle.Bold), SystemBrushes.WindowText, new Point(400, 600)); Response.ContentType = "image/jpeg"; bitMapImage.Save(Response.OutputStream, ImageFormat.Jpeg); graphicImage.Dispose(); bitMapImage.Dispose(); this is working for me but the output is in new window. but i want that the image should show in a panel. in this panel i want to show the image after it has taken text from to and from textbox

Here is the solution. Label control does not provide transparent background option, so you do have to write text over the image. However, it's not complicated.

If you have textbox1 and textbox2 as TextBox controls, and image which is PictureBox control, then you can set the image of the picture box like this:

// Here I'm creating Image img, but you will actually load it as you normally do
Image img = new Bitmap(100, 100);
using (Graphics gr = Graphics.FromImage(img))
{
    SolidBrush brush = new SolidBrush(Color.DarkRed);
    gr.FillRectangle(brush, new Rectangle(new Point(0, 0), img.Size));
}

image.Tag = img;        // Set both Tag and Image of the picture box - Tag will contain the original image
image.Image = img;

// handling TextChanged event in textbox1 and textbox2 with same method

textbox1.TextChanged += new EventHandler(TextBoxTextChanged);
textbox2.TextChanged += new EventHandler(TextBoxTextChanged);

Now TextBoxTextChanged method is crucial - it will modify the picture shown in picture box:
void TextBoxTextChanged(object sender, EventArgs e)
{

    Image img = (Image)image.Tag;
    img = (Image)img.Clone();

    using (Graphics gr = Graphics.FromImage(img))
    {
       
        SizeF t1Size = gr.MeasureString(textbox1.Text, this.Font);
        SizeF t2Size = gr.MeasureString(textbox2.Text, this.Font);

        Brush brush = new SolidBrush(Color.Yellow);
        gr.DrawString(textbox1.Text, this.Font, brush, new PointF(0, 0));
        gr.DrawString(textbox2.Text, this.Font, brush, new PointF(img.Width - t2Size.Width, img.Height - t2Size.Height));

    }

    image.Image = img;

}

This method picks up the original image from the Tag property, clones it (important, because you can't modify original image multiple times) and then draws two strings over it. Once done, new Image value is set in the picture box. Result is that picture box changes its appearance with every keystroke on the text box.

But in what form? Do you want two transparent labels to be shown above the image box?

Do you want to change the image so that it contains text drawn on it?

The code which does that is this:

textbox1.Location = image.Location;
textbox2.Location = new Point(image.Right - textbox2.Width, image.Bottom - textbox2.Height);
textbox1.BringToFront();
textbox2.BringToFront();
