is it possible that a similar bug was introduced in the latest version?

[Hemalatha Chiranjeevulu]

Hi Aaron,

Thank you for your update.

We suspect that the reported issue might be due to assemblies are not referred properly in your machine or NuGet conflicts or the project linking settings in your application.

If you are using assemblies in your application, we suggest you remove the Syncfusion.DocIO.Portable assembly from GAC by using the following command in command prompt(ex: VS2017 Native/Cross tools command prompt) in administrator mode.

gacutil -u Syncfusion.DocIO.Portable

To know more about uninstalling the assemblies from GAC, please refer here.

If you are using NuGet packages, we suggest you try the below solution to resolve the exception issur at your side:
  1.Kindly remove the NuGet packages (Syncfusion.DocIO.Net.Core) referred in your application
  2.Delete the respective NuGet packages in “.nuget” folder which is available in “C:\Users\{XXX}\.nuget\packages” folder location.
  3.Then install the latest version v19.1.0.67 NuGet packages again in your application.
  4.Clean the solution, rebuild, and run the application.

Please let us know if you have any other questions.

Unfortunately that doesnt resolve the issue.  It changes the error however to be an error findinkg SkiaSharp

[Hemalatha Chiranjeevulu]

Hi Aaron,

Thank you for your update.

We have already faced similar kind of problem and it is fixed in our latest version of SkiaSharp NuGet. Essential DocIO internally uses SkiaSharp graphics library for measuring techniques during Word to PDF conversion process. We suspect that the reported exception issue might be due to SkiaSharp references in your project. To resolve this, we suggest you to remove all the SkiaSharp references and use SkiaSharp.NativeAssets.Linux v2.80.2 NuGet in addition to DocIORenderer NuGet package.

If you are performing Word to PDF conversion in Linux environment, please refer the below link to know more about Word to PDF conversion in Linux environment:
https://help.syncfusion.com/file-formats/docio/word-to-pdf#word-to-pdf-conversion-in-linux-os

If you are still facing the same issue means, could you please share us the below things from your side:
  1. Code snippet which used at your side.
  2. Input Word document.
  3. Environment details (OS)
  4. NuGet packages which used in your application
  5. Syncfusion product version which used in your application

This will be more helpful for us to reproduce the exact issue at our end. Thereby we will analyze further on the reported problem and update you with appropriate solution at the earliest.

Please let us know if you have any other questions.

I gave this a try and this is what I have found.

1) The native linux assets still pull in the base skia libarary.

     

2)DocIORender installs the SkiaSharpHelper library as a dependency
