開発者向けPDFライブラリ - Pdftools SDK(Toolbox add-on)

PDFを印刷用にレイアウト

印刷に適したレイアウトのPDFを作成できます。
フォームフィールドをフラット化したり、ページサイズやページの向きを設定したり、複数のページを1ページに配置したりできます。

INFO:

この機能はToolbox add-onの機能ですが、「Pdftools SDK」ライブラリ用のライセンスキーで機能します。
Toolbox add-onの全機能は無償で試用できますが、試用版のライセンスキーが必要です。
試用ライセンスキー要求からご要望ください。

ページサイズを設定

このプロジェクトでは、ページの向きを検出し、目的のページ形式に適合しない場合は自動的に回転および拡大縮小します。

ページを特定のページ形式に合わせる

PDFの各ページを指定されたのページ形式に適合させます。
