Hi Muthulakshmi,

Thanks for your inquiry. Could you please attach your input WordML document here for testing? We will investigate the issue on our side and provide you more information.

loginmuthu · May 25, 2022, 8:57am

Hi,
When converting wordml to PDF using standalone program its working fine, but when I deployed the code in server, I am facing the mentioned exception. I want to know what is the use of
WindowsNativeCall_x64.dll
and why aspose.word is expecting to install Visual C++ Redistributable Packages 2012 update
Same type of issue i found in this link
https://forum.aspose.com/t/aspose-words-for-java-dependency/32242/2
but i have no permission to view this post. Please suggest

tahir.manzoor · May 25, 2022, 8:54am

Hi Muthulakshmi,

Thanks for your inquiry. In case you are using older version of Aspose.Words, we suggest you please upgrade to the latest version of Aspose.Words for Java 16.7.0.

If you still face problem, please share your working environment e.g. operating system, Jdk version etc. along with input document and code. We will investigate the issue on our side and provide you more information.

loginmuthu · May 25, 2022, 8:58am

After upgrading to 16.7.0, used two different server machines even then the exception persists

Environment:

Windows 2008 R2 standard

Windows Server 2012 R2

JDK Version:

1.8

Code Snippet:

Please refer the screenshot Code_Snippet_with_Error.jpg

Xml file used: Refer attached Sample.xml

Before installing Visual C++ Redistributable Packages" installed (see https://www.microsoft.com/en-us/download/details.aspx?id=30679) update, got the error while converting wordml to PDF. The output_error.pdf generated with formatting issue refer 13th page of PDF where signature block split into two pages.

After installing Visual C++ Redistributable Packages" installed (see https://www.microsoft.com/en-us/download/details.aspx?id=30679) update. Wordml converted to PDF with out issue. The output_success.pdf generated without any formatting issue

Please let me know why server machine alone expecting the VS2012 update where as client machine works fine without this update.

Also let me know why aspose requires VS2012 update and some times even after installing the update the PDF conversion has formatting issues.

Please let me know whether this update is required.

tahir.manzoor · May 25, 2022, 8:58am

Hi Muthulakshmi,

Thanks for sharing the detail.

MS Word has the “Use printer metrics to lay out document” option under the “Options -> Advanced -> Compatibility options for” section. By default this feature is enabled which allows Word to check printer settings to calculate formatting and layout.

Please have a look at the Disable the “Use printer metrics to lay out document option” https://support.microsoft.com/en-us/kb/918793 section

The only way to retrieve the same metrics is to use native calls so we had to create our own “WindowsNativeCall_x86|x64.dll” which is stored in the OS temp folder.

To reduce the size of Aspose.Words’ library, we decided not to include additional libraries and let users install “Visual C++ Redistributable Packages” on their side if it has not been installed yet. So please install Visual C++ Redistributable Packages to avoid the exception.

loginmuthu · May 25, 2022, 8:59am

Hi,

Thanks for the explanation.

As per you suggestion, When I disable use printer metrics option, I didn’t get any exception but the generated PDF has formatting issues noticed that signature split up in Page 13.

My understanding is that use printer metrics is required to correct the formatting in the generated PDF. correct me if am wrong.

LoadOptions opt = new LoadOptions();
opt.setLoadFormat(LoadFormat.WORD_ML);
Document d1 = new Document("C:\4224\Sample.xml", opt);
d1.getCompatibilityOptions().setUsePrinterMetrics(false);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
d1.save(baos, SaveFormat.PDF); 
d1.save("C:\4224\output.pdf", SaveFormat.PDF);

After installing VS2012 c++ update in windows 2012 server, when I run the code in eclipse its working fine without formatting issue. When I deploy the code in server, formatting issue still persists. Any specific requirement for deploying in server.

I used Tomcat server for deployment. Please let me know how to resolve this

If VS C++2012 update is mandatory then how we can handle in case of Linux Server

tahir.manzoor · May 25, 2022, 8:54am

Hi Muthulakshmi,

Thanks for your inquiry. Please note that Aspose.Words mimics the same behavior as MS Word does. If you convert document to Pdf with/without UsePrinterMetrics option, you will get the same output.

Please note that Aspose.Words requires TrueType fonts when rendering documents to fixed-page formats (JPEG, PNG, PDF or XPS). You need to install fonts on the machine where you’re converting documents to Pdf. Please make sure that you are not using following line of code in your application.

d1.getCompatibilityOptions().setUsePrinterMetrics(false);

Hi,

Please see my inline comments

Please note that Aspose.Words mimics the same behavior as MS Word does. If you convert document to Pdf with/without UsePrinterMetrics option, you will get the same output.

When I convert the sample.xml to PDF using word with user printer metrics enabled option, I am not seeing any formatting issues, Whereas if I disable use printer metrics and convert the sample.xml to PDF I am getting the formatting issue in 13th page

I am not using the above code, but In my windows server true type font is installed in c:\windows\fonts

Even after installing 2012 update, I am getting formatting issue when code is deployed in tomcat and run as services. what library path must we include for the tomcat service to work?

Waiting for your updates.

Hi Muthulakshmi,

>> client machine works fine without this update.

Probably the client machine had already got this package.

>> If VS C++2012 update is mandatory then how we can handle in case of Linux Server

We don’t have appropriate solution for this issue on Unix-based systems yet.

We are working on it.

>> When I deploy the code in server, formatting issue still persists. Any specific requirement for deploying in server.

No specific requirements needed for deploying in servers.

Aspose Words copies the native library (WindowsNativeCall_x64.dll) into the server’s “tmp” folder which is “%TOMCAT_HOME\temp”.

Then if a document has “Use printer metrics to lay out document” option enabled, Aspose Words loads this library from the temp directory and gets the font metrics via native GDI calls.

In order to solve this problem try to perform these simple steps:

Check the log file first. Are there any exceptions?
Then check if the file %TOMCAT_HOME\temp\WindowsNativeCall\WindowsNativeCall_x64|x86.dll exists.
Then check if VS2012 package has been installed on the server machine.

Also please use the latest Aspose Words version (16.8). It has a lot of performance improvements.

Please let us know the results.

Thanks

loginmuthu · May 25, 2022, 8:54am

No exceptions. Tomcat temp folder has the dll. VisualStudio2012 C++2012 update is there. Only problem is this issue occurs when Tomcat is running as service. But when run as console its working fine. ASPOSE already locked this as defect as you can see in the previous thread from Tahir Manzoor( 770405 in reply to 769917)

tahir.manzoor · May 25, 2022, 8:54am

Hi Muthulakshmi,

Thanks for your feedback. We reproduced this issue using a simple web application. We will inform you via this forum thread once there is any update available on this issue. Thanks for your patience and understanding.
