PowerPointのFontをすべて変更するVBA (グループ化されていても!)

Posted at

やりたいこと

PowerPointで、すべてのフォントを一括で変更したい。
オートシェイプや図形、表、グラフなどを想定。
グループ化されていると、処理できなくなるので、グループ内のシェイプを再帰的に探しに行く。
とりあえず、下記のマクロで、テスト環境ではすべてのフォントがMeiryo UIに変更される。
nameFontの内容を、他のフォントに変更すれば、他のフォントへの変更も可能。

Module1
'   FontをMeiryo UIに変更する
Public Sub makeFontMeiryoUI()
    Const nameFont As String = "Meiryo UI"

    Dim col As Collection
    Dim shp As Shape
    
    Set col = New Collection
    
    Call getColShapeFromPresentation(col)   '   Presentation全体のShapeに対して処理する場合
    Call getColShapeFromSlideMaster(col)   '   SlideMasterに対しても処理をする場合
    
    For Each shp In col      '各Shapeに対して処理
        Call changeFont(shp, nameFont) 'Fontを変更する
    Next
    
End Sub

' Fontを変更する
Private Sub changeFont(ByRef shp As Shape, ByVal nameFont As String)
    Dim s As Shape
    If shp.HasTextFrame Then
        Call setFontName(shp.TextFrame.TextRange.Font, nameFont)
    ElseIf shp.HasSmartArt Then
        For Each s In shp.GroupItems
            Call changeFont(s, nameFont)
        Next
    ElseIf shp.HasTable Then
        Dim c As Cell, r As Row
        For Each r In shp.Table.Rows
            For Each c In r.Cells
                Call changeFont(c.Shape, nameFont)
            Next
        Next
    ElseIf shp.HasChart Then
        Call setFontName(shp.Chart.Format.TextFrame2.TextRange.Font, nameFont)
        For Each s In shp.Chart.Shapes
            Call changeFont(s, nameFont)
        Next
    End If
End Sub

Private Sub setFontName(ByRef f As Object, ByVal nameFont As String)
    If TypeName(f) = "Font" Or TypeName(f) = "Font2" Then
        f.Name = nameFont
        f.NameFarEast = nameFont
        f.NameAscii = nameFont
        f.NameComplexScript = nameFont
    Else
        Debug.Print "font type:", TypeName(f)
    End If
End Sub

'   Presentation全体のShapeに対して処理する場合
Public Sub getColShapeFromPresentation(ByRef col As Collection)
    Dim sld As Slide
    Dim shp As Shape
    For Each sld In ActivePresentation.Slides
        For Each shp In sld.Shapes
            Call putShapeIntoCol(shp, col)
        Next
    Next
End Sub

'   選択されたSlide内のShapeに対して処理する場合
Public Sub getColShapeFromSlide(ByRef col As Collection)
    Dim shp As Shape

    If ActiveWindow.Selection.Type < ppSelectionSlides Then Exit Sub
    For Each shp In ActiveWindow.Selection.SlideRange.Shapes
        Call putShapeIntoCol(shp, col)
    Next
End Sub

'   Group化されている場合も、個別のShapeをcolコレクションに格納
Public Sub putShapeIntoCol(ByRef shp As Shape, ByRef col As Collection)
    Dim s As Shape
    If shp.Type <> msoGroup Then
        col.Add shp
    Else
        For Each s In shp.GroupItems
            Call putShapeIntoCol(s, col)
        Next
    End If
End Sub

'   SlideMasterに対して処理する場合
Public Sub getColShapeFromSlideMaster(ByRef col As Collection)
    Dim shp As Shape
    Dim d As Design
    For Each d In ActivePresentation.Designs
        For Each shp In d.SlideMaster.Shapes.Placeholders
            Call putShapeIntoCol(shp, col)
        Next
    Next
End Sub

*リンク先のマクロは、グループ化されているときや、表やグラフが含まれているときにうまくフォントが変わらない。
