使用Interop.Excel将Excel转换为PDF时不显示图像

我正在使用Interop.Excel将Excel（xlsx）（2010）转换为应用程序的PDF。在我的显影机上，它工作正常，图像显示正确。但是，在服务器上，当excel转换为PDF时，图像（一些通过代码插入，另一些通过模板文档插入）不会显示在PDF中。查看excel文件时，该文件正常。以下是我用来转换为PDF的代码：

Public Shared Function FromExcel(ByVal ExcelFileLocation As String, ByVal PDFFileLocation As String) As Boolean

    ' Load the new Excel file
    ' http://msdn.microsoft.com/en-us/library/bb407651(v=office.12).aspx
    Dim excelApplication As ApplicationClass = New ApplicationClass()
    Dim excelWorkbook As Workbook = Nothing

    Dim paramExportFormat As XlFixedFormatType = XlFixedFormatType.xlTypePDF
    Dim paramExportQuality As XlFixedFormatQuality = XlFixedFormatQuality.xlQualityStandard
    Dim paramOpenAfterPublish As Boolean = False
    Dim paramIncludeDocProps As Boolean = True
    Dim paramIgnorePrintAreas As Boolean = True
    Dim paramFromPage As Object = Type.Missing
    Dim paramToPage As Object = Type.Missing

    Try
        ' Open the source workbook.
        excelWorkbook = excelApplication.Workbooks.Open(ExcelFileLocation)

        ' Save it in the target format.
        If Not excelWorkbook Is Nothing Then
            excelWorkbook.ExportAsFixedFormat(paramExportFormat, _
                PDFFileLocation, paramExportQuality, _
                paramIncludeDocProps, paramIgnorePrintAreas, _
                paramFromPage, paramToPage, paramOpenAfterPublish)

            Return True

        Else
            Return False
        End If

    Catch ex As Exception
        Return False
    Finally
        ' Close the workbook object.
        If Not excelWorkbook Is Nothing Then
            excelWorkbook.Close(False)
            excelWorkbook = Nothing
        End If

        ' Quit Excel and release the ApplicationClass object.
        If Not excelApplication Is Nothing Then
            excelApplication.Quit()
            excelApplication = Nothing
        End If

        GC.Collect()
        GC.WaitForPendingFinalizers()
        GC.Collect()
        GC.WaitForPendingFinalizers()

    End Try

End Function

请注意，右上角和右下角的图像是如何不显示的。任何想法都会有帮助

谢谢

我在填充单元格和changin单选按钮时遇到了类似的问题——所有图像都会消失

通过将服务帐户切换到本地系统，而不是我最初选择的“本地服务”，我可以使图像不被删除

我仍然坚持这一点，有人知道一些信息吗？另请参见：您是否找到解决方法或解决方案？
