Convert text to image in ASP.NET

In this blog we will learn how to convert text to an Image.

I have an ASP.NET page that has a TextBox control. When user enters any text to the TextBox and clicks the button, then the text is converted to an image.

Note: - Here we need two namespaces.

using System.Drawing;

using System.Drawing.Imaging;

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<body>

<div>

<asp:TextBox ID="TextBox1" runat="server" Width="200px"></asp:TextBox>

<asp:Button ID="btnconvert" runat="server" Text="Convert to image"

onclick="btnconvert_Click" />

</div>

</form>

Graphics gph1 = Graphics.FromImage(bit1);

string text;

gph1.Clear(Color.Orange);

text = TextBox1.Text;

gph1.DrawString(text, new Font("Arial", 12, FontStyle.Bold),

new SolidBrush(Color.Red), new PointF(0.4F, 2.4F));

Response.ContentType = "image/Jpeg";

bit1.Save(Response.OutputStream, ImageFormat.Jpeg);

bit1.Dispose();
