System.Drawing issue on .net 6 on linux

[majeed_s]

We recently upgraded from .net 5 to .net 6 on Linux on docker to generate powerpoints but it's failing. It seems like its something to do with System.Drawing and fontmaps?

How do we run .net 6 or above on a non-windows machine without getting this error?

Our current setup (upgrading to .net 6 causes problems).
"Microsoft.AspNetCore.Http.Features" Version="5.0.6"
"Spire.Presentation" Version="8.7.0"
"System.Drawing.Common" Version="4.6.0"

Thanks!

Hi,

Thank you for your inquiry.
Kindly note our Spire.Presentation provides the NET6 dlls, which has dependency on the System.Drawing.Common, this library is not supported on non-windows operating system from NET6.

Besides, our netstandard dll in Spire.Presentation uses the SkiaSharp to replace the System.Drawing.Common. It can work with non-windows operating system. Please download the Spire.Presentation from our website(the latest version is Spire.Presentation Pack(hot fix) Version: 9.3.4), and manually add the DLLs from the folder “netstandard2.0” into your project, then install the following dependencies from Nuget.

Code: Select all

SkiaSharp >= 1.68.0
System.Text.Encoding.CodePages >= 4.5.0
System.Security.Cryptography.Xml >=4.5.0

If there is still any questions, please feel free to write back.

running Docker on Linux (with .NET 6) we thought it would be a smooth move until we met a problem of generating a PowerPoint. It's putting via System.Drawing and fontmaps error The Entity Framework is a part of the .NET Framework which is a powerful framework for building web applications. Here is how we run .NET 6+ on a non-Windows setup. Currently our solid config however, .NET 6 update causing not smooth running.

Hi,

Thanks for your inquiry.
Just like my solution above, you need the standard version of spire.Presentation.dll, as shown in the following screenshot
