Hi guys,
i have recently downloaded the evaluation copy of the barcode code that saves a barcode into SQL Server. i am using active pdf and i wish to insert the barcode from SQL server into a pdf image field to display it. can anyone give me any guidance on how to do this ??
im using vb.net for coding purposes and im also using active pdf toolkit as a mean to populate my pdf in memory. any help on this issue appreciated. at present the barcode is in the binary image format.
Regards
Colin Graham
Hello Colin,
Thanks for considering Aspose.Barcode!
Our support team has started working on this issue, we will get back to you A.S.A.P.
Dear Colin,
Thanks for considering Aspose.
We are more than glad to provide you some demo code to demonstrates how to use Aspose.BarCode to insert image to pdf documents. Here are some points we need to make clear:
1) Which product you are using to create the pdf document? Aspose.BarCode provides the function to generate the barcode images in bmp format. If you control supports to insert the bmp image, you can use the BitmapImage property to get the bitmap and insert it to the pdf doc. The following is a demo for Aspose.BarCode and Aspose.Pdf
Me.BarCodeControl1.Resolution.DpiX = 96.0F
Me.BarCodeControl1.Resolution.DpiY = 96.0F
'//Save the barcode image to memorystream
Dim mstream As System.IO.MemoryStream = New System.IO.MemoryStream
Me.BarCodeControl1.BitmapImage.Save(mstream, System.Drawing.Imaging.ImageFormat.Bmp)
'//Create Pdf
Dim pdfFile As New Aspose.Pdf.Pdf
Dim section As Aspose.Pdf.Section = pdfFile.Sections.Add()
'//Insert BarCode Image into pdf
Dim image1 As New Aspose.Pdf.Image
image1.ImageInfo.ImageFileType = Aspose.Pdf.ImageFileType.MemoryBmp
image1.ImageInfo.OpenType = Aspose.Pdf.ImageOpenType.Memory
image1.ImageScale = 0.5
Dim reader As System.IO.BinaryReader = New System.IO.BinaryReader(mstream)
mstream.Position = 0
image1.ImageInfo.MemoryData = reader.ReadBytes(mstream.Length)
section.Paragraphs.Add(image1)
'//Save the pdf file
pdfFile.Save("BarCode.pdf")
2) It is suggest not to save the barcode image to database, instead you can only save the data that is encoded in the barcode image. And then you can get the data from sql server, and re-generate the barcode image by Aspose.BarCode. Therefore, we can save lots of network transferring and the space of the database.
The attachment of the mail is the demo about how insert barcode to pdf document with Aspose.BarCode and Aspose.Pdf, hope it makes sense.
Feel free to access me with any problems.
Hello Iret,
I am looking for a solution to a similar situation right now. We are already using Aspose.PDF for .Net to convert and merge Word Documents to a PDF file. Now we are trying to add/generate a DataMatrix barcode on each page of the PDF file, with the information such as Page Number, Document Number, etc.
Can you please give me more information on how to do this? Also, I would really appreciate if you could send a demo to try it.
Thanks,
Umanga
