Embed text in Image using ASP.NET
I've been a freelance web developer since Feb '00. Prior to that, I'd spent most of my working life in the pub trade. I'd also worked as a security guard in a local factory. Luckily, I was able to ...
Sometimes, it is nice to have a text caption embedded into an image, rather than display the caption in HTML. Fortunately, this is fairly straightforward in ASP.NET.
Look at this photo of myself. I can embed some text into the photo using the following code:
image_text.aspx
<%@ Page Language="c#"%>
<%@ Import Namespace="System.Drawing.Imaging" %>
<%@ Import Namespace="System.Drawing" %>
<%@ Import Namespace="System.Drawing.Drawing2D" %>
<script runat="server">
private void Page_Load(object sender, System.EventArgs e)
{
Bitmap bmp= new Bitmap(Server.MapPath(Request.QueryString["i"]));
Graphics g=Graphics.FromImage(bmp);
g.SmoothingMode = SmoothingMode.AntiAlias ;
g.DrawString(Request.QueryString["t"],
new Font("verdana",12),SystemBrushes.WindowText, 1, 1);
Response.ContentType="image/jpeg";
bmp.Save(Response.OutputStream, bmp.RawFormat) ;
}
</script>
For a demo, take a look at http://www.charon.co.uk/demos/image_text.aspx?i=/file_library/images/articles/jules_photo.jpg&t=Photo+of+Jules. Play around with the querystring. See how the caption changes when you change the text in the querystring.
