使用 Excel VBA 在 word 中调整图像大小

Question

我在 excel VBA 中有这段代码，它可以创建一个 word 文档并粘贴我的屏幕截图。我接下来要做的是调整图像大小，以便我可以在一个页面中容纳更多图像，不幸的是我真的不知道粘贴图像后下一步该怎么做

Sub Testing()
    Dim wrd As Word.Application

    Set wrd = Word.Application

    With wrd
      .Visible = True
      .Activate
      .Documents.Add
      Call PrintScreen
      .Selection.Paste
      'What should i do next?
    end with

End Sub

您可以通过将图片插入到具有固定高度和宽度的表格单元格中来限制插入到 Word 中的图片的大小。

以下宏允许用户选择多个图像以插入到表中，该表具有他们选择的列数和他们选择的图片行高。表格列宽由页面打印宽度决定。每张图片下方都添加了说明文字。

Sub AddPics()
Application.ScreenUpdating = False
Dim i As Long, j As Long, c As Long, r As Long, NumCols As Long
Dim oTbl As Table, TblWdth As Single, StrTxt As String, RwHght As Single
On Error GoTo ErrExit
NumCols = CLng(InputBox("How Many Columns per Row?"))
RwHght = CSng(InputBox("What max height for the pictures, in centimeters (e.g. 5)?"))
On Error GoTo 0
'Select and insert the Pics
With Application.FileDialog(msoFileDialogFilePicker)
  .Title = "Select image files and click OK"
  .Filters.Add "Images", "*.gif; *.jpg; *.jpeg; *.bmp; *.tif; *.png"
  .FilterIndex = 2
  If .Show = -1 Then
    'Create a paragraph Style with 0 space before/after & centre-aligned
    On Error Resume Next
    With ActiveDocument
      .Styles.Add Name:="TblPic", Type:=wdStyleTypeParagraph
      On Error GoTo 0
      With .Styles("TblPic").ParagraphFormat
        .Alignment = wdAlignParagraphCenter
        .SpaceAfter = 0
        .SpaceBefore = 0
      End With
    End With
    'Add a 2-row by NumCols-column table to take the images
    Set oTbl = Selection.Tables.Add(Range:=Selection.Range, NumRows:=2, NumColumns:=NumCols)
    With ActiveDocument.PageSetup
      TblWdth = .PageWidth - .LeftMargin - .RightMargin - .Gutter
    End With
    With oTbl
      .AutoFitBehavior (wdAutoFitFixed)
      .Columns.Width = TblWdth / NumCols
    End With
    CaptionLabels.Add Name:="Picture"
    For i = 1 To .SelectedItems.Count Step NumCols
      r = ((i - 1) / NumCols + 1) * 2 - 1
      'Format the rows
      Call FormatRows(oTbl, r, RwHght)
      For c = 1 To NumCols
        j = j + 1
        'Insert the Picture
        ActiveDocument.InlineShapes.AddPicture _
          FileName:=.SelectedItems(j), LinkToFile:=False, _
          SaveWithDocument:=True, Range:=oTbl.Cell(r, c).Range
        'Get the Image name for the Caption
        StrTxt = Split(.SelectedItems(j), "\")(UBound(Split(.SelectedItems(j), "\")))
        StrTxt = ": " & Split(StrTxt, ".")(0)
        'Insert the Caption on the row below the picture
        With oTbl.Cell(r + 1, c).Range
          .InsertBefore vbCr
          .Characters.First.InsertCaption _
          Label:="Picture", Title:=StrTxt, _
          Position:=wdCaptionPositionBelow, ExcludeLabel:=False
          .Characters.First = vbNullString
          .Characters.Last.Previous = vbNullString
        End With
        'Exit when we're done
        If j = .SelectedItems.Count Then Exit For
      Next
      'Add extra rows as needed
      If j < .SelectedItems.Count Then
        oTbl.Rows.Add
        oTbl.Rows.Add
      End If
    Next
  Else
  End If
End With
ErrExit:
Application.ScreenUpdating = True
End Sub

Sub FormatRows(oTbl As Table, x As Long, Hght As Single)
With oTbl
  With .Rows(x)
    .Height = CentimetersToPoints(Hght)
    .HeightRule = wdRowHeightExactly
    .Range.Style = "TblPic"
    .Cells.VerticalAlignment = wdCellAlignVerticalCenter
  End With
  With .Rows(x + 1)
    .Height = CentimetersToPoints(0.5)
    .HeightRule = wdRowHeightExactly
    .Range.Style = "Caption"
  End With
End With
End Sub

按照编码，宏对标题行使用“标题”样式。这使标题左对齐。它还为图像行使用自定义的“TblPic”样式，确保图片在其单元格中水平居中并正确填充可用空间。单元格也垂直居中。您可以更改任何这些参数。
