Dear Fayyaz,

I am very thankful for your prompt response. I am using barcode. I have to print barcode on very specific location on pre-printed labels. I am attaching sample file for pre-printed label.Problem.png (8.4 KB)

Thank you for your feedback. We are investigating your specific scenario and will update you as soon as additional information is available.


You can create a PDF file according to the dimensions of the document and position the Barcode image on the document using Aspose.PDF for .NET API. Given below is the sample code snippet that you can use to generate the document. Please modify the height and width according to the actual document.

Dim doc As Aspose.Pdf.Document = New Aspose.Pdf.Document()
Dim page As Aspose.Pdf.Page = doc.Pages.Add()
page.PageInfo.Height = 3 * 72
page.PageInfo.Width = 7 * 72
page.PageInfo.Margin = New Aspose.Pdf.MarginInfo(2 * 72, .5 * 72, .2 * 72, .5 * 72)
Dim BarCodeImage As Aspose.Pdf.Image = New Aspose.Pdf.Image()
BarCodeImage.File = "TestGS1DataMatrix.png"
BarCodeImage.FixHeight = 2 * 72
BarCodeImage.FixWidth = 4 * 72

Furthermore, to generate Barcode with specified dimensions, you can use the code snippet provided on the link given below.

Dear Ahmad,

Thanks for your quick support. I am sorry that I might not communicate my issue properly to you. Actually, I have to print the GS1Datamatrix directly, (Without saving it as PNG or BMP using builder.print). The Space, where I have to print GS1Datamatrix, is very calculated (I am attaching Sample FIle). For printing precisely, Page Size, Margins etc should be set to get the job done. I am expecting to get help on setting page size, margins, Human Readable Text settings etc. Please help me in sorting this issue.

You may set the margins for the Barcode by using the code snippet given below.

builder.Margins = New Aspose.BarCode.MarginsF(20, 2, 2, 3)

To set the font of the text displayed, use builder.CodeTextFont property.

builder.CodeTextFont = New System.Drawing.Font("Verdana", 50.0F)

To set the size of the generated Barcode image, you may set the ImageHeight and ImageWidth properties.

builder.GraphicsUnit = GraphicsUnit.Inch
builder.ImageHeight = 3
builder.ImageWidth = 7

We hope that this solved the issue that you were facing. Please feel free to reach us if additional information is required.
