DoctoPdfConverter fails on relatively large doc

[Travis Chambers]

Hi, I am trying to convert a 29 page Word document with about 15 pictures in it to pdf using the doctopdfconverter. When I use the code on a small, simplistic doc it works just fine. But with this large one it tries for a several minutes before the app goes into break mode. 

To be sure my code isnt missing anything I tried using the word conversion sample provided in essentialstudio but had the same result. If I open the doc in Word and export to pdf from there it has no problems. Word itself exports it to pdf in about 2 seconds, so it appears that docio has some sort of limitation that Word does not have.

This doc is 6,870 kb in size. Does the doctopdfconverter have some sort of file size limitation? I cannot share the pdf with you due to privacy concerns, but any general info you can provide will be greatly appreciated.

Thanks.

Hi Travis,

Thank you for contacting Syncfusion support.

We have tried to reproduce the issue in our end, but we can't reproduce the issue in our end. Please find the sample used in our end from the following link.
https://www.syncfusion.com/downloads/support/forum/149111/ze/Sample1247512093.zip

Does the doctopdfconverter have some sort of file size limitation?
No, there is no limitation in our DocIO library for PDF conversion based on the file size.

If you continue to face the issue, we request to use the below property to convert the Word to PDF using fast rendering approach. 

//Creates an instance of the DocToPDFConverter - responsible for Word to PDF conversion
DocToPDFConverter converter = new DocToPDFConverter();
//Sets true to enable the fast rendering using direct PDF conversion. converter.Settings.EnableFastRendering = true; 

If there is identical images in the Word document, we request to enable the below property. 

//Sets true to optimize the memory usage for identical images converter.Settings.OptimizeIdenticalImages = true; 

If the issue continues, we suspect that the problem might be due to the contents in the specific input Word document which used at your end. So, could you please provide us the Word document (mandatory) with complete code example to reproduce the problem in our end.

Thereby we will analyze further and provide you the appropriate solution at the earliest.

Note: If you have any confidential data in your Word document, please replace with some dummy data and provide us the same. We just need your document to recreate the problem you face.

I have tried the fast rendering and optimiation options but they do not help. I have modified the doc as much as I can in order to share it. Please see attached.

The code I am using is pulled form the essential studio sample:

   string doc = "File path";

                        WordDocument wordDocument = new WordDocument(doc);

                        //Initializes the ChartToImageConverter for converting charts during Word to pdf conversion

                        wordDocument.ChartToImageConverter = new ChartToImageConverter();

                        //Creates an instance of the DocToPDFConverter

                        DocToPDFConverter converter = new DocToPDFConverter();

                    converter.Settings.AutoDetectComplexScript = true;

                    converter.Settings.EnableFastRendering = true;

                    converter.Settings.OptimizeIdenticalImages = true;

                        //Converts Word document into PDF document

                        PdfDocument pdfDocument = converter.ConvertToPDF(wordDocument);

                        //Saves the PDF file 

                        pdfDocument.Save("New Path");

                        //Closes the instance of document objects

                        pdfDocument.Close(true);

                        wordDocument.Close();

Hi,

Thank you for all of the help. However, I am not able to try this patch because it is apparently only for a certain version, which is lower than the version I am currently using (17.4.0.39). Can I get this patch for the newer version?

Thanks!
