XSSFPicture.Resize method locks application execution

[fiantsev]

Description:

I used code example from poi https://poi.apache.org/components/spreadsheet/quick-guide.html#Images - it's about inserting image into spreadsheet.

my code

public void Main()
        {
            IWorkbook workbook = GetWorkbook();
            byte[] imageByteArray = LoadImage();
            var sheet = workbook.GetSheetAt(0);

            var pictureIndex = workbook.AddPicture(imageByteArray, PictureType.JPEG);
            var drawing = sheet.CreateDrawingPatriarch();

            var anchor = workbook.GetCreationHelper().CreateClientAnchor();
            anchor.Col1 = 0;
            anchor.Row1 = 0;

            var picture = (NPOI.XSSF.UserModel.XSSFPicture)drawing.CreatePicture(anchor, pictureIndex);

            picture.Resize();//deadlock here
        }

 

Result:  

Application deadlocks on line picture.Resize();//deadlock here

Expected behaviour:

no deadlock and image autoresized

I have tried nuget packages: NPOI 2.5.1
My project has target: .Net Core 3.1
Machine: Windows 10

How to avoid deadlock/resize image correctly?

Is it possible for you to use https://www.nuget.org/packages/NPOI/ and see if this issue also exists? If so, this is a bug.

@tonyqus
oh sorry for misleading info - I tried your package NPOI 2.5.1 too - result is the same - execution locks.

I used this sample and add picture.Resize(). But I cannot reproduce your issue.
