Notes:
- The entire image of the specified page is converted to PNG and saved. GoogleSlidesExport
- If no page is specified, the last page will be converted to PNG.
- The download URL to the image is tagged with the account of the requester.
- Anyone with the URL effectively accesses the image as the original requester.
- Access to the image may be lost if the presentation's sharing settings change.
- If need to specify the size, replace =s1600 at the end of the URL with =s1200. (As of 2021-05)
- For example, if you want to automate the notification of "Monthly Sales Report", define as follows:
- The template page is automatically duplicated (Google Slides: Page, Duplicate)
- The report text part is automatically replaced (Google Slides: Page, Replace Strings)
- The embedded graph is automatically updated (Google Slides: Page, Refresh Charts)
- The slide page is automatically converted to a PNG image (Google Slides: Page, Generate PNG)
- The email with the PNG image attached will be sent automatically. (ThrowEmail Event)
Notes-ja:
- 指定ページのページ全体をPNG化して保存します。 GoogleSlidesExport
- もしページ指定がない場合は、最終ページをPNG化します。
- ダウンロード用URL(30分間のみ有効)はAPI通信の認可者に紐づけられます。
- URLを知っている人は誰でも画像にアクセスできます。そして認可者によるアクセスと見なされます。
- なお、ファイルの共有設定が変更されるとダウンロード用URLは無効になります。
- サイズ指定が必要な場合、URL末尾の =s1600 を =s1200 に書き換えるなどして下さい。(2021-05現在)
- たとえば「月次売上レポート」の通知業務を自動化したい場合は、以下のような業務プロセスを定義します。
- 雛形ページが自動複製され、(※Google スライド: ページ, 複製)
- 貼り付けられている埋め込みグラフが自動更新され、(※Google スライド: ページ, 文字列全置換)
- 報告テキスト部が当月文に自動置換され、(※Google スライド: ページ, 全グラフ更新)
- 当該スライドページがPNG画像に自動変換され、(※Google スライド: ページ, PNG画像生成)
- PNG画像が添付されたメールが自動的に送信される。(※ ThrowEmail イベント)
