我需要自动创建演示文稿(OpenOffice或Powerpoint)。演示文稿应将每个演示文稿的前两张幻灯片放在给定目录中,然后将它们组合成一个演示文稿。我对于应该采取什么方法来解决这个问题感到困惑。任何指针将不胜感激。

最佳答案

在谈论PowerPoint时,您将使用VBA宏来完成这项工作,例如

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

选择您的源目录,您可以使用此功能
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。这是一件棘手的事情,因为PPT VBA InsertFromFile方法没有什么用处。微软给了我们很多时间来解决无数20小时调试 session 中的难题:-),并且您需要键入很多代码才能正确完成它-比手动使用对话要复杂得多,尤其是如果您的源代码幻灯片与您的源主幻灯片有所不同。

如果您的PPT坚持使用其母版,则可以安全地省略“>>>>”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
                        Select Case SrcSld.Background.Fill.TextureType
                        Case Is = msoTexturePreset
                            .Background.Fill.PresetTextured (SrcSld.Background.Fill.PresetTexture)
                        Case Is = msoTextureUserDefined
                        ' TextureName gives a filename w/o path
                        ' not implemented, see picture handling
                        End Select

                    Case Is = msoFillSolid
                        .Background.Fill.Transparency = 0#
                        .Background.Fill.Solid

                    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.Export SrcPPT.Path & SrcSld.SlideID & ".png", "PNG"

                        .Background.Fill.UserPicture SrcPPT.Path & SrcSld.SlideID & ".png"
                        Kill (SrcPPT.Path & SrcSld.SlideID & ".png")

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

                    Case Is = msoFillPatterned
                        .Background.Fill.Patterned (SrcSld.Background.Fill.Pattern)

                    Case Is = msoFillGradient

                        ' inspect gradient type
                        Select Case SrcSld.Background.Fill.GradientColorType
                        Case Is = msoGradientTwoColors
                            .Background.Fill.TwoColorGradient
                                SrcSld.Background.Fill.GradientStyle , _
                                SrcSld.Background.Fill.GradientVariant
                        Case Is = msoGradientPresetColors
                            .Background.Fill.PresetGradient _
                                SrcSld.Background.Fill.GradientStyle, _

                    Case Is = msoFillBackground
                        ' Only shapes - we shouldn't come here
                End Select

该代码不检查只读或受密码保护的小 Sprite ,它们会崩溃。另外请注意不要在收集器文件本身上运行。否则它应该工作。我必须承认我已经很长时间没有审查代码了;-)
