NullReferenceException in ExtractImages

[glarreur]

Hello,

I use FreeSpire.PDF with nuget 6.10.6 and when I debug the following code with vs I have a null references exception:

Code: Select all

     PdfDocument pdfDocument = new PdfDocument();
                pdfDocument.LoadFromBytes(pictureData);

                var pdfPage = pdfDocument.Pages[0];
                var images = pdfPage.ExtractImages(); // the exception occurs at this line
                var image = images[0];


Code: Select all

System.NullReferenceException : 'Object reference not set to an instance of an object.'
Stack trace:    at sprᜒ.ᜂ(Stream A_0)


What is strange is when I do not use vs but dotnet watch run no error occurs. Any idea ?

I have made a test with FreeSpire.PDF V6.10.6 in both VS2017 and VS2019 but did not reproduce your issue. To help us reproduce the issue, please provide us with your input file, your system information (E.g. Win7, 64 bit) and region setting (E.g. China, Chinese) for reference.

Thanks in advance.
