I'm using this extension to merge a couple of PDf files that contains Scanned images into one PDf document. What I have is the following situation:
1. Each scanned image will be posted to the server in one PDF file. so I get a Record list ( dataset) of each image in a pdf file.
2. Once I receive the whole HTTP request I check for each record if the binary is not a null binary ( I do a compare) and append all of them to the record list of the type PDF (structure) in the iTextSharp extension,
3. After step 2 I call the MergePDF_Bulk function to merge all the files in one single PDF.
Here I get the following error in servicecenter :
 PDF header signature not found. at iTextSharp.text.pdf.PRTokeniser.CheckPdfHeader() at iTextSharp.text.pdf.PdfReader.ReadPdf() at OutSystems.NssiTextSharp.CssiTextSharp.MssMergePDF_Bulk(RLPDFRecordList ssPDF_List, Byte& ssMergedPDF)
I just need to have all the images in a pdf file.
**** Update ****
I saved each file in a table so I can access each Pdf separately to check if the pdf is correct, and only the first pdf is correct, the rest when I try to open them I get that the file is corrupt. So I think that is the issue.
