Convert Text to Image in ASP.NET

Convert Text to Image in ASP.NET

In this article I will explain how to create Text to image in ASP.NET.

Take a text box,button and image control.

In HTML page add the following Code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:TextBox runat="server" ID="txtText"></asp:TextBox>
    <asp:Button ID="btnConvert" runat="server" Text="Convert" OnClick="btnConvert_Click" />
    <hr />
    <asp:Image ID="imgText" runat="server" Visible="false" />
    </form>
</body>
</html>


In C# page add the following Code:


using System.Drawing.Text;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.IO;
using System.Drawing.Imaging


Add the following code in button click event:
protected void btnConvert_Click(object sender, EventArgs e)
{
    string text = txtText.Text.Trim();
    Bitmap bitmap = new Bitmap(1, 1);
    Font font = new Font("Arial", 25, FontStyle.Regular, GraphicsUnit.Pixel);
    Graphics graphics = Graphics.FromImage(bitmap);
    int width = (int)graphics.MeasureString(text, font).Width;
    int height = (int)graphics.MeasureString(text, font).Height;
    bitmap = new Bitmap(bitmap, new Size(width, height));
    graphics = Graphics.FromImage(bitmap);
    graphics.Clear(Color.White);
    graphics.SmoothingMode = SmoothingMode.AntiAlias;
    graphics.TextRenderingHint = TextRenderingHint.AntiAlias;
    graphics.DrawString(text, font, new SolidBrush(Color.FromArgb(255, 0, 0)), 0, 0);
    graphics.Flush();
    graphics.Dispose();
    string fileName = Path.GetFileNameWithoutExtension(Path.GetRandomFileName()) + ".jpg";
    bitmap.Save(Server.MapPath("~/images/") + fileName, ImageFormat.Jpeg);
    imgText.ImageUrl = "~/images/" + fileName;
    imgText.Visible = true;
}



Run the code.
