Hi!
I have a situation where we are converting word documents to pdf -files and then merging these converted pdfs’ to a single pdf -file using Aspose.Pdf.Facades.PdfFileEditor
This process has worked well with the Aspose.Pdf version 10.9 that we have used previously, but we with the lates version 11.5 the resulting document is 0 bytes in length.
Aspose.Words version is 16.3.0.0
Aspose.Pdf versions tried:
* 10.9.0.0 (working as expected)
* 11.5.0.0 (Not working)
Attached are two files: document1.docx and document2.docx. Copy these files to C:\Temp\PdfConcat -folder, edit the program code to reflect your environment and run it
using Aspose.Pdf.Facades;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Reflection;
namespace PdfConcat
{
class Program
{
private static Aspose.Pdf.License _pdfLicense;
private static Aspose.Words.License _wordsLicense;
private static string _inputFile1Path = @"C:\Temp\PdfConcat\document1.docx";
private static string _inputFile2Path = @"C:\Temp\PdfConcat\document2.docx";
private static string _outputFilePath = @"C:\Temp\PdfConcat\pdf_concat_version_" + Assembly.LoadFrom("Aspose.Pdf.dll").GetName().Version.ToString() + ".pdf";
//path to your Aspose.pdf license file
private static string _pdfLicensePath = @"";
//path to your Aspose.Words license file
private static string _wordsLicensePath = @"";
static Program()
{
_pdfLicense = new Aspose.Pdf.License();
_pdfLicense.SetLicense(_pdfLicensePath);
_wordsLicense = new Aspose.Words.License();
_wordsLicense.SetLicense(_wordsLicensePath);
}
static void Main(string[] args)
{
List documents = new List
{
docxToPdf(File.ReadAllBytes(_inputFile1Path)),
docxToPdf(File.ReadAllBytes(_inputFile2Path))
};
PdfFileEditor pdfEditor = new PdfFileEditor();
using (MemoryStream outputStream = new MemoryStream())
{
var inputStreams = new MemoryStream[documents.Count];
try
{
for (int i = 0; i < documents.Count; i++)
{
inputStreams[i] = new MemoryStream(documents[i]);
}
pdfEditor.Concatenate(inputStreams, outputStream);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
finally
{
//0 bytes written with Aspose.Pdf version 11.5.0.0
//Works as expected with Aspose.Pdf version 10.9.0.0
File.WriteAllBytes(_outputFilePath, outputStream.ToArray());
for (int i = 0; i < inputStreams.Count(); i++)
{
inputStreams[i].Dispose();
}
}
Console.ReadLine();
}
}
private static byte[] docxToPdf(byte[] bytes)
{
using (var outputStream = new MemoryStream())
{
using (var inputStream = new MemoryStream(bytes))
{
var doc = new Aspose.Words.Document(inputStream);
doc.Save(outputStream, Aspose.Words.SaveFormat.Pdf);
return outputStream.ToArray();
}
}
}
}
}
