System.Drawing was deprecated on .NET 6 and there does not seem to be a replacement ready from Aspose for macOS and Linux.
I have attached a test project which fails completely on macOS, and partially on Linux.
On macOS libgdiplus is used internally and cannot be found.
We are currently using .NET 5 in our production code and cannot upgrade to .NET 6 only because of Aspose. We are paying a lot for the Aspose.Total license and expect that this should be fixed a.s.a.p
