Aspose excel is converted to PDF. The images in excel are only a few tens of kilobytes, turning into PDF images into thousands of kilobytes

Please tell me Aspose.Cells can call PDF995 printing when transferring PDF file. Cells transfer PDF to enlarge the image in the document. After testing Excel to PDF. It’s going to add a big black background to the picture. As the picture grows larger, so does the PDF. If it’s a PDF printed out of PDF995, the comparison will be hundreds of times different.

            Dim WorkFolder As String = rc.TempPath
            Dim WorkFileName As String
            WorkFileName = WorkFolder & "\\" & Path.GetFileNameWithoutExtension(fileName) & ".pdf"
            WorkFileName = WorkFileName.Replace("(", "_").Replace(")", "_")
            excelApp = New Workbook(fileName)
            Dim xlsSaveOption As Aspose.Cells.PdfSaveOptions = New Aspose.Cells.PdfSaveOptions()
            xlsSaveOption.SecurityOptions = New Aspose.Cells.Rendering.PdfSecurity.PdfSecurityOptions()
            xlsSaveOption.SecurityOptions.ExtractContentPermission = False
            xlsSaveOption.SecurityOptions.PrintPermission = True
            xlsSaveOption.SecurityOptions.OwnerPassword = rc.OwnerPassword
            xlsSaveOption.AllColumnsInOnePagePerSheet = True
            xlsSaveOption.EnableHTTPCompression = True
            excelApp.Save(WorkFileName, xlsSaveOption)


Aspose.Cells for .NET has its own implementation of printing a file and a third party routine can not be used for printing with Aspose.Cells. Please attach source and output files for our reference so that it can be investigated further.

Attached is the test I did. PDF is turned out with Aspose. Other tools go to PDF_864293. PDF is made with Other tools. The difference between the two files is huge. Please help to solve whether there is a good solution.
