Hello,

We are running Aspose.Cells in a linux docker container.

https://hub.docker.com/_/microsoft-dotnet-core-runtime/

During runtime, we get the following error when trying to save an Excel file to PDF.

System.PlatformNotSupportedException: System.Drawing is not supported on this platform.
   at System.Drawing.Imaging.ImageFormat.get_Emf()
   at Aspose.Cells.PdfSaveOptions..ctor(SaveOptions )
   at Aspose.Cells.FileFormatUtil.(String , FileFormatType , SaveFormat , SaveOptions)
   at Aspose.Cells.Workbook.Save(Stream stream, SaveFormat saveFormat)

The version we are using is Aspose.Cells 20.3.0.

@randysimplist,
libgdiplus is required by Aspose.Cells while running on docker container. You may please follow the steps below where Ubuntu 18.04.2 LTS (Bionic Beaver) is used by us in a docker container and share the feedback.

Here are the steps:

  1. The docker I use is: microsoft/dotnet, install it first:
    sudo docker pull microsoft/dotnet
  2. Then I install libgdiplus:

apt-get update
apt-get install -y libgdiplus
cd /usr/lib && ln -s libgdiplus.so gdiplus.dll

  1. And install libc6-dev:

apt-get install -y --no-install-recommends libc6-dev

Thank you for the prompt reply.

We resolved the issue on our end. It was due to a missing deps.json file.
