Generate Image of any Text

Create Image of Text on Fly.zip

In this article I am going to show how we can generate image of any text.

Below is my aspx code:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!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>Generate Image of Text</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table style="width: 90%; background-color: #F5F5F5; border: solid 10px Green;" align="center"
cellpadding="10" cellspacing="10">
<tr>
<td height="10px" style="background-color: Yellow; font-weight: bold; font-family: Georgia;
font-size: 18pt; color: Red;" align="center">
Generate Image of Your Text
</td>
</tr>
<tr>
<td>
Enter Text #:
<asp:TextBox runat="server" ID="txtYourText" Width="300px"></asp:TextBox>
<asp:Button ID="btnConvert" runat="server" Text="Generate Image" OnClick="btnGenerateImage _Click" />
</td>
</tr>
<tr>
<td>
<asp:Image ID="imgText" runat="server" Visible="false" />
</td>
</tr>
</table>
</div>
</form>
</body>
</html>

Below is my aspx.cs code:

public partial class _Default : System.Web.UI.Page

}
protected void btnGenerateImage_Click(object sender, EventArgs e)
{
string text = txtYourText.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();
Random random = new Random();
string fileName = Convert.ToString(random.Next(1, 2000)) + ".jpg";
bitmap.Save(Server.MapPath("~/MyTextImages/") + fileName, ImageFormat.Jpeg);
imgText.ImageUrl = "~/MyTextImages/" + fileName;
imgText.Visible = true;
}
}
