Python でプレゼンテーションを効率的に結合

プレゼンテーション結合の最適化

With Aspose.Slides for Python, you can seamlessly combine PowerPoint presentations while preserving styles, layouts, and all elements. Unlike other tools, Aspose.Slides merges presentations without compromising quality or losing data. Merge entire decks, specific slides, or even different file formats (e.g., PPT to PPTX).

結合機能

• フルプレゼンテーション結合: すべてのスライドを単一のファイルにまとめます。
• 特定スライド結合: 選択したスライドを組み合わせます。
• クロスフォーマット結合: 異なる形式のプレゼンテーションを統合し、整合性を保ちます。

プレゼンテーション結合

When you merge one presentation into another, you are effectively combining their slides into a single presentation to produce one file. Most presentation programs—such as PowerPoint or OpenOffice—do not provide features that let you merge presentations in this way.

However, Aspose.Slides for Python allows you to merge presentations in several ways. You can merge presentations with all their shapes, styles, text, formatting, comments, and animations, without any loss of quality or data.

結合可能なもの

With Aspose.Slides, you can merge:

• 全体のプレゼンテーション: ソースデッキのすべてのスライドが単一のプレゼンテーションに結合されます。
• 特定スライド: 選択したスライドだけが単一のプレゼンテーションに結合されます。
• 同一形式のプレゼンテーション (例: PPT→PPT, PPTX→PPTX) または異なる形式間 (例: PPT→PPTX, PPTX→ODP).

結合オプション

You can control whether:

• Each slide in the output presentation retains its original style, or
• A single style is applied to all slides in the output presentation.

To merge presentations, Aspose.Slides provides the add_clone methods on the SlideCollection class. These method overloads define how the merge is performed. Every Presentation object exposes a slides collection, so you call add_clone on the destination presentation’s slide collection.

The add_clone method returns an Slide—a clone of the source slide. Slides in the output presentation are copies of the originals, so you can modify the resulting slides (for example, apply styles, formatting, or layouts) without affecting the source presentations.

プレゼンテーションの結合

Aspose.Slides provides the add_clone(ISlide) method, which allows you to combine slides while preserving their layouts and styles (using default parameters).

The following Python example shows how to merge presentations:

import aspose.slides as slides

with slides.Presentation("presentation1.pptx") as presentation1:
    with slides.Presentation("presentation2.pptx") as presentation2:
        for slide in presentation2.slides:
            presentation1.slides.add_clone(slide)
        presentation1.save("combined.pptx", slides.export.SaveFormat.PPTX)

スライドマスターを使用したプレゼンテーション結合

Aspose.Slides provides the add_clone(ISlide, IMasterSlide, Boolean) method, which allows you to merge slides while applying a slide master from a template. This way, when needed, you can restyle the slides in the output presentation.

The following Python example demonstrates this operation:

import aspose.slides as slides

with slides.Presentation("presentation1.pptx") as presentation1:
    with slides.Presentation("presentation2.pptx") as presentation2:
        for slide in presentation2.slides:
            presentation1.slides.add_clone(slide, presentation1.masters[0], True)
        presentation1.save("combined_with_master.pptx", slides.export.SaveFormat.PPTX) 

To apply a different slide layout to slides in the output presentation, use the add_clone(ISlide, ILayoutSlide) method when merging.

プレゼンテーションから特定スライドを結合

Merging specific slides from multiple presentations is useful when creating custom slide decks. Aspose.Slides lets you select and import only the slides you need, while preserving the original slides’ formatting, layout, and design.

The following Python example creates a new presentation, adds title slides from two other presentations, and saves the result to a file:

def get_title_slide(pres):
    for slide in pres.slides:
        if slide.layout_slide.layout_type == slides.SlideLayoutType.TITLE:
            return slide
    return None


with slides.Presentation() as presentation, \
        slides.Presentation("presentation1.pptx") as presentation1, \
        slides.Presentation("presentation2.pptx") as presentation2:
    presentation.slides.remove_at(0)

    slide1 = get_title_slide(presentation1)
    if slide1 is not None:
        presentation.slides.add_clone(slide1)

    slide2 = get_title_slide(presentation2)
    if slide2 is not None:
        presentation.slides.add_clone(slide2)

    presentation.save("combined.pptx", slides.export.SaveFormat.PPTX)

スライドレイアウトを使用したプレゼンテーション結合

The following Python example shows how to merge slides from multiple presentations while applying a specific slide layout to produce a single output presentation:

import aspose.slides as slides

with slides.Presentation("presentation1.pptx") as presentation1:
    with slides.Presentation("presentation2.pptx") as presentation2:
        for slide in presentation2.slides:
            presentation1.slides.add_clone(slide, presentation1.layout_slides[0])
        presentation1.save("combined_with_layout.pptx", slides.export.SaveFormat.PPTX) 

異なるスライドサイズのプレゼンテーション結合

To merge two presentations with different slide sizes, first resize one presentation so its slide size matches the other’s.

The following sample code demonstrates this process:

import aspose.slides as slides

with slides.Presentation("presentation1.pptx") as presentation1:
    slide_size = presentation1.slide_size.size
    with slides.Presentation("presentation2.pptx") as presentation2:
        presentation2.slide_size.set_size(slide_size.width, slide_size.height, slides.SlideSizeScaleType.ENSURE_FIT)
        for slide in presentation2.slides:
            presentation1.slides.add_clone(slide)
        presentation1.save("combined_size.pptx", slides.export.SaveFormat.PPTX) 

プレゼンテーションセクションにスライドを結合

The following Python example shows how to merge a specific slide into a section of a presentation:

import aspose.slides as slides

with slides.Presentation("presentation1.pptx") as presentation1:
    with slides.Presentation("presentation2.pptx") as presentation2:
        for slide in presentation2.slides:
            presentation1.slides.add_clone(slide, presentation1.sections[0])
        presentation1.save("combined_sections.pptx", slides.export.SaveFormat.PPTX) 

The slide is added at the end of the section.

よくある質問

結合時にスピーカーノートは保持されますか？

はい。スライドをクローンすると、Aspose.Slides はノート、書式設定、アニメーションを含むすべてのスライド要素を引き継ぎます。

コメントとその作成者は転送されますか？

コメントはスライドコンテンツの一部としてコピーされ、コメント作成者のラベルは結果のプレゼンテーション内のコメントオブジェクトとして保持されます。

ソースのプレゼンテーションがパスワードで保護されている場合はどうなりますか？

パスワードで開く 必要があります。LoadOptions.password を使用してロードした後、そのスライドは保護されていないターゲットファイル（または保護されたファイル）に安全にクローンできます。

結合操作はどの程度スレッドセーフですか？

同じ Presentation インスタンスを 複数のスレッド から使用しないでください。推奨ルールは「1 ドキュメント ‑ 1 スレッド」です。別々のファイルは別スレッドで並行処理できます。
