Hello, I get “libpng warning: pHYs: CRC error” when using Aspose.Tasks on Linux with mono framework. This happens when Tasks exports to PDF or PNG. Export to MPX works fine.
Can you please share source file along with sample code so that we may further investigate to help you out.
Hello, I am trying different options to get Aspose.Tasks export to PDF working on linux using Net Core and mono. I have no problem with Cells and Words but Tasks issues all about Encoding and export to Pdf. It works with MPP format and save files but Pdf does not properly work.
Now I have the following error using mono on linux:
Unhandled Exception:

After adding Encoding.RegisterProvider(CodePagesEncodingProvider.Instance); to the project I start getting the following:
