调整邮件项目中粘贴的JPEG的大小

我试图从Excel表格发送一张图片,但大小非常小。

我怎样才能得到一个合适的尺寸(基本上是整个屏幕)?

Sub send_as_a_pic()
    'Copy range of interest
    Dim r As Range
    Set r = Range("B2:O23")
    r.Copy

    'Open a new mail item
    Dim outlookApp As Outlook.Application
    Set outlookApp = CreateObject("Outlook.Application")
    Dim outMail As Outlook.MailItem
    Set outMail = outlookApp.CreateItem(olMailItem)

    With outMail
        .To = "fernando.grespan@fernando.com"
        .CC = ""
        .BCC = ""
        .Subject = "PAC 2017 sales up to date"
    End With

    'Get its Word editor
    outMail.Display
    Dim wordDoc As Word.Document
    Set wordDoc = outMail.GetInspector.WordEditor

    'To paste as picture
    wordDoc.Range.PasteAndFormat wdChartPicture

    'With wordDoc.Range
     '   .LockAspectRatio = True
      '  .Top = wordDoc.Top
       ' .Left = wordDoc.Left
        '.Height = wordDoc.RowHeight
    'End With

End Sub
