自动化 – 以编程方式将多个演示文稿中的幻灯片组合到一个演示

我需要自动创建演示文稿(OpenOffice或Powerpoint).演示文稿应采用给定目录中每个演示文稿的前两张幻灯片,然后将它们合并为一个演示文稿.我很困惑我应该采取什么方法来解决这个问题.任何指针将不胜感激.
谈到PowerPoint,你可以使用VBA宏来完成这项工作

Sub Pull()
Dim SrcDir As String, SrcFile As String

    SrcDir = PickDir()
    If SrcDir = "" Then Exit Sub

    SrcFile = Dir(SrcDir & "\*.ppt")

    Do While SrcFile <> ""
        ImportFromPPT SrcDir + "\" + SrcFile, 1, 2
        SrcFile = Dir()
    Loop

End Sub

选择源目录可以使用此功能

Private Function PickDir() As String
Dim FD As FileDialog

    PickDir = ""

    Set FD = Application.FileDialog(msoFileDialogFolderPicker)
    With FD
        .Title = "Pick a directory to work on"
        .AllowMultiSelect = False
        .Show
        If .SelectedItems.Count <> 0 Then
            PickDir = .SelectedItems(1)
        End If
    End With

End Function

现在 – 重点是从另一个PPT插入幻灯片,同时保留源格式.这是一个棘手的事情,因为PPT VBA InsertFromFile方法没有用处.微软给了我们很多时间在无数20小时的调试会话中找出困难的方法:-)而且你需要键入大量代码才能正确完成 – 比手动使用对话要复杂得多,特别是如果你的源幻灯片偏离源主幻灯片.

如果你的PPT坚持他们的主人,你可以安全地省略“>>>>”之间的所有代码

Private Sub ImportFromPPT(FileName As String, SlideFrom As Long, SlideTo As Long)
Dim SrcPPT As Presentation, SrcSld As Slide, Idx As Long, SldCnt As Long

    Set SrcPPT = Presentations.Open(FileName, , , msoFalse)
    SldCnt = SrcPPT.Slides.Count

    If SlideFrom > SldCnt Then Exit Sub
    If SlideTo > SldCnt Then SlideTo = SldCnt

    For Idx = SlideFrom To SlideTo Step 1
        Set SrcSld = SrcPPT.Slides(Idx)
        SrcSld.Copy
        With ActivePresentation.Slides.Paste
            .Design = SrcSld.Design
            .ColorScheme = SrcSld.ColorScheme
            ' if slide is not following its master (design, color scheme)
            ' we must collect all bits & pieces from the slide itself

            ' >>>>>>>>>>>>>>>>>>>>

            If SrcSld.FollowMasterBackground = False Then
                .FollowMasterBackground = False
                .Background.Fill.Visible = SrcSld.Background.Fill.Visible
                .Background.Fill.ForeColor = SrcSld.Background.Fill.ForeColor
                .Background.Fill.BackColor = SrcSld.Background.Fill.BackColor

                ' inspect the FillType object
                Select Case SrcSld.Background.Fill.Type
                    Case Is = msoFillTextured

                    Case Is = msoFillPicture
                        ' picture cannot be copied directly, need to export and re-import slide image
                        If SrcSld.Shapes.Count > 0 Then SrcSld.Shapes.Range.Visible = False
                        bMasterShapes = SrcSld.DisplayMasterShapes
                        SrcSld.DisplayMasterShapes = False

                        SrcSld.DisplayMasterShapes = bMasterShapes
                        If SrcSld.Shapes.Count > 0 Then SrcSld.Shapes.Range.Visible = True

                        ' Only shapes - we shouldn't come here

代码不会检查只读或密码保护的fies并且会崩溃.还要注意不要在收集器文件本身上运行.否则它应该工作.我必须承认我很长时间没有审查过代码;-)
