Centering Barcode onto PDF Document


I am creating a PdfCode128ABarcode (guess it doesn't matter which one we use, applies to all). I am currently setting "PdfCode128ABarcode.Draw(PdfPage, new PointF(x, y))" to place my barcode. I want to know if there is a way to center a barcode within a certain sized space? I have a 1"x4" area. The issue I can't figure is how to center the barcode at all times. This is an issue because our barcode data can vary, anywhere from 1-6 characters all the way up to 16 characters. The shorter the data, the more off center the barcode is and looks ugly. Longer data barcodes look just great, its just the shorter ones are not so pretty. The "TextAlignment" or "TextDisplayLocation" will not help me.

The "PdfGraphics.DrawString", for text, has a "PdfStringFormat" that allows me to set the "Alignment = PdfTextAlignment.Center", its what I essentially want for the whole barcode itself. Help?

Hi Gilson ,

Thank you for using Syncfusion Products .

We are created the workaround to draw the barcode at center for variable barcode text length in PDF .Please refer the following code snippet to calculate the width

  //get the barocde image

System.Drawing.Image img= barcode128A.ToImage();


 float width = 0;


//calculate the width respective to the barcode image width


 if(img.Width >page.GetClientSize().Width/2)



    width =page.GetClientSize().Width/4;








  width = (page.GetClientSize().Width/2)-img.Width/2;



We have attached the sample for your reference in below link :


Please try this and  let us know if you have further assistance .

We have logged  the feature request for “ Align the barcode at center of the  Pdf “ . We will let you know once we  have implemented .

Hi Abirami Selvan,

I tested out your solution, and it does center on the PDF page, which is great!
In my original post, I mentioned I needed to center the barcode in an "area" of 1" x 4" (example I am doing is a 20-up Avery 1" x 4" labels - http://www.worldlabel.com/assets/thumbnails/wl-75.jpg).
I will see if I can figure something out with what you gave me, to start with. If you have a solution, please let me know.
