プレゼンテーションを作成、管理する

このページでは、プレゼンテーションに関する次のような上位レベルの操作を行う方法について説明します。

  • プレゼンテーションを作成する
  • 既存のプレゼンテーションをコピーする

以下で、これらの操作について詳細に説明します。

空のプレゼンテーションを作成する

プレゼンテーションを作成するには、次の例に示すように、presentations コレクションの create メソッドを使用します。

この例では、指定したタイトルの空のプレゼンテーションを作成します。

Apps Script

slides/api/Snippets.gs
/**
 * Creates a presentation
 * @returns {*} the created presentation
 */
function createPresentation() {
  try {
    const presentation = Slides.Presentations.create({
      title: title
    });
    console.log('Created presentation with ID: %s', presentation.presentationId);

    return presentation;
  } catch (err) {
    // TODO (Developer) - Handle exception
    console.log('Failed with error: %s', err.error);
  }
};

Go

slides/snippets/presentations.go
// Create a presentation and request a PresentationId.
p := &slides.Presentation{
	Title: "Title",
}
presentation, err := slidesService.Presentations.Create(p).Fields(
	"presentationId",
).Do()
if err != nil {
	log.Fatalf("Unable to create presentation. %v", err)
}
fmt.Printf("Created presentation with ID: %s", presentation.PresentationId)

    presentation = service.presentations().create(presentation)
        .setFields("presentationId")
        .execute();
    // Prints the newly created presentation id.
    System.out.println("Created presentation with ID: " + presentation.getPresentationId());
    return presentation.getPresentationId();

Google ドライブのフォルダを操作する

Google Slides API を使用して、指定したドライブ フォルダ内に直接プレゼンテーションを作成するオプションはありません。デフォルトでは、作成されたプレゼンテーションはドライブのルートフォルダに保存されます。

ただし、ドライブ フォルダにファイルを保存する方法は他に 2 つあります。

  • プレゼンテーションを作成したら、Drive API の files.update メソッドを使用して、特定のフォルダに移動します。ファイルの移動の詳細については、フォルダ間でファイルを移動するをご覧ください。
  • Drive API の files.create メソッドを使用して、mimeTypeapplication/vnd.google-apps.presentation を指定し、空のプレゼンテーションをフォルダに追加します。ファイルの作成の詳細については、フォルダにファイルを作成するをご覧ください。

どちらの方法でも、適切な Drive API スコープを追加して呼び出しを承認する必要があります。

共有ドライブ フォルダ内でファイルを移動または作成するには、共有ドライブのサポートを実装するをご覧ください。

既存のプレゼンテーションをコピーする

プレゼンテーションをコピーするには、Drive API の files().copy メソッドを使用します。

次の例では、プレゼンテーションのタイトルおよび新しいドライブ ファイルの名称に指定の文字列を使用し、既存のプレゼンテーションをコピーしています。

Apps Script

slides/api/Snippets.gs
/**
 * create a presentation and copy it
 * @param {string} presentationId - ID of presentation to copy
 * @returns {*} the copy's presentation id
 */
function copyPresentation(presentationId) {
  const copyTitle = 'Copy Title';

  let copyFile = {
    title: copyTitle,
    parents: [{id: 'root'}]
  };
  try {
    copyFile = Drive.Files.copy(copyFile, presentationId);
    // (optional) copyFile.id can be returned directly
    const presentationCopyId = copyFile.id;

    return presentationCopyId;
  } catch (err) {
    // TODO (Developer) - Handle exception
    console.log('Failed with error: %s', err.error);
  }
};

Go

slides/snippets/presentations.go
// Copy a presentation.
