Image became black when converting to PDF

Hello team,

I have conveted PQ2274.xlsx to PDF with Aspose.Cells 17.7. I got PQ2274.xlsx.pdf but image in the pdf became black.

PQ2274.zip (191.7 KB)
PQ2274.xlsx.pdf (9 KB)

This is my code.

   private MemoryStream ConvertExcelToPdf()
    {
        MemoryStream pdfStream = new MemoryStream();

        // Instantiate the License class
        Aspose.Cells.License license = new Aspose.Cells.License();
        license.SetLicense("Aspose.Total.lic");

        // Convert .xls and .xlsx file to PDF.
        Workbook book = new Workbook(this._stream);
        book.Save(pdfStream, Aspose.Cells.SaveFormat.Pdf);

        return pdfStream;
    }

Thank you,
