In this article we will discuss to convert text to image using System.Drawing namespace. Using Graphics property we can convert text it in to bitmap image and save it the specified loction.
Step 1: Copy and paste the following code in the design page Default.aspx.
<%@ Page Language="C#" AutoEventWireup="true" CodeFile=" Default.aspx.cs" Inherits="CS" ValidateRequest="false" EnableEventValidation="false" %>
<!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>convert text toimage </title>
</head>
<body>
<form id="form1" runat="server">
<asp:TextBox runat="server" TextMode="MultiLine" Rows="5" Columns="6" Width="250px" ID="txtText"></asp:TextBox>
<asp:Button ID="btnConvert" runat="server" Text="Convert"
OnClick="btnConvert_Click" />
<asp:Image ID="imgText" runat="server" Visible="false" />
</form>
</body>
</html>
Step 2: Copy and paste the following code in the Default.aspx.cs.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Drawing.Text;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.IO;
using System.Drawing.Imaging;
public partial class Default : System.Web.UI.Page
{
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;
}
}
