データをプレゼンテーションに統合する

Google Slides API の便利な用途の 1 つは、1 つ以上のデータソースの情報をテンプレート化されたスライド資料に統合することです。

このページでは、外部ソースからデータを取得して、既存のテンプレートプレゼンテーションに挿入する方法について説明します。このコンセプトは、ワードプロセッサとスプレッドシートを使用したメールの統合に似ています。

このアプローチが有用である理由はいくつかあります。

デザイナーは Google スライドエディタを使用することで、プレゼンテーションのデザインを簡単に微調整できます。この方法は、アプリ内のパラメータを調整してレンダリングされるスライドのデザインを設定するよりもはるかに簡単です。
コンテンツをプレゼンテーションから分離するというのは有名なデザインの原則で、多くのメリットがある。

統合のイメージ図。

基本的なレシピ

次の例は、Slides API を使用してデータをプレゼンテーションに統合する方法を示しています。

デザインに適したプレースホルダコンテンツを使用して、期待する外観どおりにプレゼンテーションを作成する。
挿入するコンテンツ要素ごとに、プレースホルダコンテンツをタグに置き換えます。タグは一意の文字列を含むテキストボックスまたはシェイプです。普段使われない文字列を使用します。たとえば、{{account-holder-name}} などのタグを使うといいでしょう。
コード内で Google Drive API を使用して、プレゼンテーションのコピーを作成します。
コード内で、一式の replaceAllText リクエストを指定して Slides API の batchUpdate メソッドを呼び出し、プレゼンテーション全体ですべてのテキストを置換します。replaceAllShapesWithImage リクエストを使用して、プレゼンテーション全体で画像を置換します。

タグを設定したスライド資料を作成したら、必ずコピーして、そのコピーを Slides API で操作してください。Slides API を使用してプライマリ「テンプレート」のコピーを操作しないでください。

以降のセクションでは、このプロセスの例となるコードスニペットを紹介しています。また、上の動画では、以下の各セクションの概念をいくつか組み合わせた例（Python）について説明しています。

テキストを結合する

replaceAllText リクエストを使用すると、プレゼンテーションに含まれる任意の文字列のインスタンスを、すべて新しいテキストで置換できます。統合する場合は、テキストの個々のインスタンスを個別に検出して置換するよりも簡単です。これが最も高度な方法である理由の 1 つとして、共同編集者がテンプレートプレゼンテーションの改善や管理を行う場合は特に、ページ要素の ID が予測しづらくなるという理由があります。

例

この例では、Drive API を使用してテンプレートプレゼンテーションをコピーし、プレゼンテーションの新しいインスタンスを作成します。その後、Google Sheets API を使用してスプレッドシートからデータを読み込み、最後に Slides API を使用して新しいプレゼンテーションを更新します。

この例では、スプレッドシート上の名前付きの範囲の 1 行に含まれる 3 つのセルからデータを取得します。その後、文字列 {{customer-name}}、{{case-description}}、{{total-portfolio}} が使用されている箇所に、そのデータを代入します。

画像を統合する

replaceAllShapesWithImage リクエストを使用して、画像をプレゼンテーションに統合することもできます。このリクエストによって、指定の文字列を含むシェイプのインスタンスがすべて指定の画像に置換されます。また、画像がタグシェイプの境界内に収まるように、アスペクト比を保持したまま、自動的に画像の位置やサイズが調整されます。

例

この例では、Google Drive API を使用してテンプレートプレゼンテーションをコピーし、プレゼンテーションの新しいインスタンスを作成します。その後、Slides API を使用して、テキスト {{company-logo}} を含むシェイプを検出し、企業ロゴの画像に置き換えます。このリクエストでは、テキスト {{customer-graphic}} を含むシェイプも別の画像に置き換えられます。

特定のテキストボックスや画像のインスタンスの置換

replaceAllText リクエストと replaceAllShapesWithImage リクエストは、プレゼンテーション全体でタグを置換する際には便利ですが、特定のスライドにある要素だけを置換するなど、別の条件に基づいて要素の置換を行いたい場合もあります。

そうしたケースでは、置換したいタグシェイプの ID を取得する必要があります。テキストの置換では、そのシェイプ内に存在する既存のテキストを削除して、新しいテキストを挿入します（特定のシェイプ内のテキストを編集するの例をご覧ください）。

画像の置換はさらに複雑になります。以下は、画像の統合に必要な処理です。

タグシェイプの ID を取得します。
タグからサイズと変換情報をコピーする。
そのサイズと変換情報を使用して画像をページに追加する。
タグシェイプを削除します。

次のセクションで説明するように、画像のアスペクト比を保持したまま、期待するサイズにスケーリングするには注意が必要です。シェイプタグを画像で置き換えるのサンプルもご覧ください。

アスペクト比を維持する

Slides API を使用して画像を作成すると、画像のサイズと変換データではなく、画像のサイズのみを基準にしてアスペクト比を保ったままサイズ変更が行われます。createImage リクエストで指定したサイズのデータは、画像の期待サイズであると見なされます。この API は、画像のアスペクト比をこの希望のサイズに合わせてから、指定された変換を適用します。

タグを画像で置換する際は、以下のように画像のサイズとスケーリングを設定して、画像のアスペクト比を維持します。

width: タグの width と scaleX を掛けた値に設定
height: タグの height と scaleY を掛けた値に設定
scale_x: 1 に設定
scale_y: 1 に設定

これにより、Slides API ではスケーリングしていないサイズではなく、タグの表示サイズに基づいて、アスペクト比を保ったまま画像のサイズを変更します（シェイプタグを画像で置換するをご覧ください）。スケーリングパラメータを 1 に設定すると、画像が 2 回スケーリングされるのを防ぐことができます。

このような準備をしておくと、画像のアスペクト比が維持され、画像のサイズがタグシェイプよりも大きくなることはありません。画像の中心はタグシェイプの中心と同じになります。

テンプレートを管理する

テンプレートプレゼンテーションをアプリで定義および所有する場合は、そのアプリ専用のアカウントを使用してテンプレートを作成してください。サービスアカウントを利用すると、共有を制限する Google Workspace ポリシーによる複雑さを回避できます。

テンプレートからプレゼンテーションのインスタンスを作成する際は、必ずエンドユーザーの認証情報を使用してください。そうすることで、作成したプレゼンテーションをユーザー側で完全に制御できるため、Google Drive のユーザー単位の制限によって生じるスケーリングの問題を回避することができます。

サービスアカウントを使用してテンプレートを作成するには、アプリの認証情報を使用して次の手順を実施します。

Slides API の presentations.create を使用してプレゼンテーションを作成します。
Drive API の permissions.create を使用して、プレゼンテーションの受信者がプレゼンテーションを読み取れるように権限を更新します。
Drive API の permissions.create を使用して、テンプレートの作成者が書き込みを行えるように権限を更新します。
必要に応じてテンプレートを編集します。

プレゼンテーションのインスタンスを作成するには、ユーザーの認証情報を使用して次の手順を実行します。

Drive API の files.copy を使用してテンプレートのコピーを作成します。
Slides API の presentation.batchUpdate を使用して値を置換する。
