pdf.Pages.Add().Paragraphs.Add(image);
pdf.Save(outputStream);
return outputStream.ToArray();
}
}

The error you are encountering, “The type initializer for ‘Gdip’ threw an exception,” typically occurs when using the System.Drawing.Common library on non-Windows platforms, such as Linux. This library is not fully supported on Linux, which leads to the System.PlatformNotSupportedException you are seeing.

To resolve this issue, you can switch to using the Aspose.Pdf.Drawing library instead of Aspose.Pdf. The Aspose.Pdf.Drawing library does not have a dependency on System.Drawing, making it more suitable for Linux environments. Additionally, you may need to install the libgdiplus package on your Linux server to ensure that the API functions correctly.

Here’s a modified version of your code that uses Aspose.Pdf.Drawing:

using (var imageStream = new MemoryStream(inputBytes))
{
    using (var outputStream = new MemoryStream())
    {
        var pdf = new Aspose.Pdf.Document();
        var image = new Aspose.Pdf.Drawing.Image() { ImageStream = imageStream };
        pdf.Pages.Add().Paragraphs.Add(image);
        pdf.Save(outputStream);
        return outputStream.ToArray();
    }
}

Make sure to reference the correct namespaces and ensure that you have the latest version of Aspose.Pdf.Drawing installed. This should help you avoid the issues related to System.Drawing.Common on your Azure Linux deployment.

If you continue to experience issues, please let us know, and we can assist you further.

Getting below error with some large image type
Unable to convert Image document to pdf : : Cannot allocate so many bytes. Use LoadPartialPixels instead

@cdayalal

If possible, can you please share your sample image with us as well so that we can test the scenario in our environment and address it accordingly.

I am able to get the pdf version with small image file but when I am goes above 40Mb it throws error.

Instead of updating package can we installed the required library in docker container.

Can you please suggest me which library should i need to install ?

@cdayalal

You should install Aspose.Pdf.Drawing instead of Aspose.PDF for .NET from NuGet and it should work without any issues in docker. Please try it and let us know if you still notice any issues. Also, please make sure to use a valid license while using the API.

I already tried with Aspose.Pdf.Drawing package for conversion but it will not work with large image file it seems it can not allocate so many bytes and suggest to LoadPartialPixels

And regarding the licence currently I am using trial for test
