7/20/2014 - By Pranav Singh 0

This article will show you how you can convert text into image(.jpg) format using c#.net In asp.net. In this we will click on button control to display the entered text into image format.

So for this article first we will create a new asp.net application and add button control, a textcontrol and an image control to display the converted text into image.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="HtmlTextToOImage.aspx.cs"
    Inherits="demoasp_net.HtmlTextToOImage" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>How to Convert Text Into Image(.jpg) Format Using C#.Net In Asp.Ne</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="TextBox1" runat="server" Width="198px"></asp:TextBox>
        <br />
        <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
        <br />
    </div>
    <div>
        <asp:Image ID="Image1" runat="server" Width="200" Height="60" />
    </div>
    </form>
</body>
</html>

Now click on button to generate the button click event and add the below code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Drawing;
using System.Drawing.Imaging;

namespace demoasp_net
{
    public partial class HtmlTextToOImage : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            Image1.ImageUrl = Convert.ToString(GenerateImage("Vinay"));
        }
        public Bitmap GenerateImage(string imgText)
        {
            Color FontColor = Color.Blue;
            Color BackColor = Color.White;
            String FontName = "Arial";
            int FontSize = 60;
            int Height = 100;
            int Width = 300;
            Bitmap bitmap = new Bitmap(Width, Height);
            Graphics graphics = Graphics.FromImage(bitmap);
            Color color = Color.Gray; ;
            Font font = new Font(FontName, FontSize);
            SolidBrush BrushForeColor = new SolidBrush(FontColor);
            SolidBrush BrushBackColor = new SolidBrush(BackColor);
            Pen BorderPen = new Pen(color);
            Rectangle displayRectangle = new Rectangle(new Point(0, 0), new Size(Width - 1, Height - 1));
            graphics.FillRectangle(BrushBackColor, displayRectangle);
            graphics.DrawRectangle(BorderPen, displayRectangle);

            StringFormat format1 = new StringFormat(StringFormatFlags.NoClip);
            StringFormat format2 = new StringFormat(format1);
            graphics.DrawString(imgText, font, Brushes.Blue, (RectangleF)displayRectangle, format2);
            Response.ContentType = "image/jpeg";
            bitmap.Save(Response.OutputStream, ImageFormat.Jpeg);
            return bitmap;
        }
    }
}

Now run the application see the output.
