第三方的组件建议还是去看他们官方的帮助文档。
提示的错误是New Workbook()这里是没有参数的，至于怎么传入文件，还是去看他们帮助吧

Dim book As Aspose.Cells.Workbook = New Aspose.Cells.Workbook(tmp)
For Each sheet As Aspose.Cells.Worksheet In book.Worksheets
Dim options As Aspose.Cells.Rendering.ImageOrPrintOptions = New Aspose.Cells.Rendering.ImageOrPrintOptions()
options.HorizontalResolution = 200
options.VerticalResolution = 200
options.ImageType = Aspose.Cells.ImageType.Jpeg
Dim sr As SheetRender = New SheetRender(sheet, options)
For j As Integer = 0 To sr.PageCount - 1
sr.ToImage(j, dataDir + sheet.Name & " Page" + (j + 1) & ".out.jpg")
Next

options.ImageType -- 没有ImageType 这个属性
