Aspose.Slides.Presentation Throws “The Type Initializer for ‘Gdip’ Threw Exception”

Aspose.Slides Product Family

I was redirected to this subforum from Aspose.PDF, where similar problem took place, but was solved by linking another library (Aspose.PDF.Document throws "The type initializer for 'Gdip' threw exception"). But now we need solution for Slides.

While trying to generate PDF with PPT we get the exception:
The type initializer for ‘Gdip’ threw exception

var loadOptions = new Aspose.Slides.LoadOptions();
loadOptions.LoadFormat = LoadFormat.Ppt;
var presentation = new Aspose.Slides.Presentation(filePath, loadOptions);
presentation.Save (newPath, Aspose.Slides.Export.SaveFormat.Pdf); // <-- error "Gdip" line

On windows that code works perfectly. Supposedly, error occurs because of “System.Drawing” usage, instead of Aspose.Drawing in Slides.

Need help and/or workaround.

Aspose.Slides 22.12.0
.NET 6.0
OS: Ubuntu 20.04

@prorigo,
The issue is still open. Unfortunately, I don’t have any additional information yet.

We are getting the same error in our Docker image on LINUX. It works great on our local Windows box in the same container. What is an ETA for it to be fixed?

Thank You,

@SergTomcat,
Our developers have investigated the case. The exception occurs because the libgdiplus library is missing, which is required by older versions of System.Drawing.Common in Linux environments. To install libgdiplus on WSL with Ubuntu 20.04, execute the following command in the terminal:

sudo apt update && sudo apt install -y libgdiplus

To install libgdiplus in Docker, add the following script to your Dockerfile:

RUN apt-get update && apt-get install -y libgdiplus
