Hello All,

Note: I got this error initially but it was gone after i installed:
apt-get update && apt-get install -y apt-utils libgdiplus libc6-dev

The type initializer for ‘Gdip’ threw an exception.
System.TypeInitializationException: The type initializer for ‘Gdip’ threw an exception.

Hi Raed,

GemBox components currently have dependency to System.Drawing.Common which uses “libgdiplus” package on Linux. So, please try installing that package:

sudo apt install libgdiplus

Does this solve your issue?

Also just as an FYI, we’re currently in the process of removing this dependency.

Regards,
Mario

Dear mario.gemboxm
I also have the same issue.
I added “RUN apt-get update && apt-get install -y libgdiplus” in Dockerfile, but the issue not resolve, I still see a black square instead of a image like window server.

Hi,

Please check our Docker example:

Have you added the following packages to your project:

<PackageReference Include="HarfBuzzSharp.NativeAssets.Linux" Version="*" />
<PackageReference Include="SkiaSharp.NativeAssets.Linux" Version="*" />

Hi mario.gembox,

I added both HarfBuzzSharp.NativeAssets.Linux and SkiaSharp.NativeAssets.Linux by NuGet but Issue not resolved.
