Spire.Doc.Document: Save to pdf very slow

[cdf]

Hi,

I have an issue with the licensed version of Spire.Doc for .NET. I am trying to save a .docx document to pdf with your library and it takes around 100 seconds to export the document.

This is the code:

Code: Select all

Spire.Doc.Document doc = new Spire.Doc.Document();
doc.LoadFromFile(@"d:\WordWith175pages.docx"); //5365 ms
doc.SaveToFile(@"d:\export_.pdf", Spire.Doc.FileFormat.PDF); //122984 ms

I have used another tools to export the document (online tools, printers, MS Word export,etc.) and these tools export the document to pdf in less than 10 seconds.

Can you help me with this problem? I am using the lastest version of Spire.Doc.

Best Regards,

The input docx file has confidential data.

Can I send it you by email? If it is possible, please tell me an email.

Hello Carlos,

Regarding your reported issue, I got the news from our Dev team that it is hard to do an optimization for the big file. Since based on our internal conversion mechanism, it need to get font information from system installed fonts according to the font used in Word document, this step costs a long time. However, in MS Word, the system font information has been integrated when installing and doesn't need to be got when doing conversion. Thus, converting by MS Word will be faster. Hope you can understand. Sorry for the inconvenience caused.

Ref - Spire.doc Java (3.9.0)
It works pretty well with word document manipulation just that it takes so much time to load it into memory, approx 2 minutes for 150 pages docx file.
I have two questions:
1. Is it normal or it should not take this much time?
2. Only available latest Word format is 2013 in code, is there going to support for newer version as well in future?

Hello Saurav,

Thanks for your inquiry.
Below are my answers to your questions.
1) Many factors have impacts on the loading speed, such as the file content complexity and you testing environment. To help us better investigate your issue, please provide your Word sample file and the testing environment ( E.g. Windows 10, 64bit, JDK1.8 ). You could attach your file here or send to us via email (support@e-iceblue.com). Thanks in advance.
2) Our Spire.Doc supports loading the higher version Word files like Word 2016 or above, but at present our Spire.Doc doesn't provide the FileFormat.Docx_2016 to specify the fileformat. We will consider adding this feature into our upgrade list, once it is achieved in the future, I will inform you immediately.
