Please look at my sample project here. I have dockerfile in the project as well.
I have installed libgdiplus and installed nuget package SkiaSharp.NativeAssets.Linux.NoDependencies
I am trying to remove black pages from pdf using aspose pdf.
The type initializer for ‘Gdip’ threw an exception.

We already logged an issue to test Aspose.PDF functionality under .NET 6.0 in non-Windows environments as PDFNET-50918. You will be notified via this forum thread once this issue is resolved.
Is there a official versions compatibility chart vs different OS for aspose pdf and aspose words. We were planning to migrate to dotnet 6 and start using linux seems like this is the only blocker. We updated our license just for this only to realize this is not supported in linux. Any pointers to what our options are at this point would be helpful.
Unfortunately, there is no compatibility chart vs different operating systems. However, you can find your required detail in following articles of Aspose.PDF and Aspose.Words.
Seems like this task PDFNET-50918 has been floating around for almost a year. I see oldest mention of the task here:
Its from November 2021. Its been almost a year and this task seems to still be not worked on. What is the status and priority of this task? Do we have any idea when this will be addressed?
I am afraid we do not have luxury to wait on this any longer.
We have logged your concerns in our issue tracking system. We will inform you once there is an update available on it. We apologize for your inconvenience.
Here we are its Nov 8th 2022. Microsoft will release dotnet 7 later today and PDFNET-50918 is one year old at this point. And there is no clear communication on what is going on with this task.
How long should we wait? mind you we bought new license just so that we could upgrade to dotnet 6.
Please give us more details than this issue is being logged.
The release of Aspose.PDF beta version is scheduled and will be available by the end of November 2022. Please note that this ETA is not final at the moment. We will be sure to inform you once there is any news available on it.
Yes, 22.11 is the beta version and we are further improving this feature and doing more and more tests. You can also use it and share your feedback in case you notice any issues.
Unfortunately the Aspose.PDF@22.11.0 version does not solve the problem on dotnet7. Still getting System.PlatformNotSupportedException: System.Drawing.Common is not supported on non-Windows platforms.
Just adding Aspose.PDF.Drawing does not change the behaviour: I’m using PngDevice to export single pages of a PDF which throws on Linux the following Exception with StackTrace:
System.PlatformNotSupportedException: System.Drawing.Common is not supported on this platform.

You only need to install Aspose.PDF.Drawing instead of Aspose.PDF. Aspsoe.PDF with Drawing contains Aspose.Drawing inside, installing neither System.Drawing nor Aspose.Drawing is required.
This assembly correctly works under Linux environment. It will be published as separated assembly until we sure that this works absolutely perfect and may replace current System.Drawing-based assembly by 100%. When we ensure that, we will replace System.Drawing version with Aspose.Drawing one.
I removed Aspose.PDF: seems to work!
I get now an exception in Aspose.Imaging but I will open an Issue there.
