Barcode with Text Under using ItextSharp
This is code I found while searching the net. Hope this solves your problem:
string prodCode = context.Request.QueryString.Get("code");
context.Response.ContentType = "image/gif";
if (prodCode.Length > 0)
{
Barcode128 code128 = new Barcode128();
code128.CodeType = Barcode.CODE128;
code128.ChecksumText = true;
code128.GenerateChecksum = true;
code128.StartStopText = true;
code128.Code = prodCode;
System.Drawing.Bitmap bm = new System.Drawing.Bitmap(code128.CreateDrawingImage(System.Drawing.Color.Black, System.Drawing.Color.White));
bm.Save(context.Response.OutputStream, System.Drawing.Imaging.ImageFormat.Gif);
}
There is no direct way to display text below the barcode image using iTextSharp dll. I tried the same and had a workaround to display the text. This is not a direct solution, but will provide output similar to what is expected out of a barcode image.
To generate the barcode image, i used the inputs shared by JP Hellemons in his blog. Thanks JP Hellemons! http://www.jphellemons.nl/post/Make-a-code128-barcode-with-C-sharp-and-iTextSharp.aspx
The code that i used:
Barcode128 code128 = new Barcode128();
code128.CodeType = iTextSharp.text.pdf.Barcode.CODE128;
code128.ChecksumText = true;
code128.GenerateChecksum = true;
code128.StartStopText = false;
code128.Code = <<Barcode value>>;
// Create a blank image
System.Drawing.Bitmap bmpimg = new Bitmap(120,35); // provide width and height based on the barcode image to be generated. harcoded for sample purpose
Graphics bmpgraphics = Graphics.FromImage(bmpimg);
bmpgraphics.Clear(Color.White); // Provide this, else the background will be black by default
// generate the code128 barcode
bmpgraphics.DrawImage(code128.CreateDrawingImage(System.Drawing.Color.Black, System.Drawing.Color.White), new Point(0, 0));
//generate the text below the barcode image. If you want the placement to be dynamic, calculate the point based on size of the image
bmpgraphics.DrawString(<<Barcode value>>, new System.Drawing.Font("Arial", 8, FontStyle.Regular), SystemBrushes.WindowText, new Point(15, 24));
// Save the output stream as gif. You can also save it to external file
bmpimg.Save(context.Response.OutputStream, System.Drawing.Imaging.ImageFormat.Gif);
Correct me if I was wrong..
If any of you have a direct or simpler solution, please share them..
