在PowerPoint演示文稿中更改所有方程式颜色的宏

如何解决在PowerPoint演示文稿中更改所有方程式颜色的宏

我正在用许多数学方程式进行PowerPoint演示。 我想问一下是否有任何方法可以自动更改这些方程式的颜色。 我找到了一个解决方案，但是它是针对Word文档的： https://www.codeproject.com/Tips/1378034/Macro-to-Change-the-Color-of-all-Equations-in-a-Wo

Sub Change_Equation_Color()
  'Macro to Change the Font Color of all Equations in a Word Document
   Dim Eq As OMath
   For Each Eq In ActiveDocument.OMaths
   Eq.Range.Select
   Selection.Font.ColorIndex = wdDarkBlue 'Choose Color here,e.g. wdBlack
   'Selection.Font.TextColor.RGB = RGB(255,255) 'To use RGB color,uncomment this line and comment the one above
Next
End Sub

不幸的是，此宏在PowerPoint中不起作用。您能为此提供任何解决方案吗？

谢谢！

解决方法

相当于PowerPoint：

Sub ColorEquation()
    Dim oSlide As Slide
    Dim oShape As Shape
    For Each oSlide In ActivePresentation.Slides
        For Each oShape In oSlide.Shapes
            If oShape.HasTextFrame Then
                If oShape.TextFrame2.HasText Then
                    If oShape.TextFrame2.TextRange.MathZones.Length > 0 Then
                        oShape.TextFrame2.TextRange.Font.Fill.ForeColor.RGB = RGB(255,255)
                    End If
                End If
            End If
        Next oShape
    Next oSlide
End Sub

,

在第 8 行使用 Count 而不是 Length。

  Sub ColorEquation()
        Dim oSlide As Slide
        Dim oShape As Shape
        For Each oSlide In ActivePresentation.Slides
            For Each oShape In oSlide.Shapes
                If oShape.HasTextFrame Then
                    If oShape.TextFrame2.HasText Then
                        If oShape.TextFrame2.TextRange.MathZones.Count > 0 Then
                            oShape.TextFrame2.TextRange.Font.Fill.ForeColor.RGB = RGB(255,255)
                        End If
                    End If
                End If
            Next oShape
        Next oSlide
    End Sub
