フリーハンドの注釈を使用すると、ユーザーは独自のカスタム描画要素を使用してドキュメント上の領域を強調できるため、コラボレーションが充実

The ability to draw freehand annotations in PDF viewers allows users to directly mark up documents with digital ink, creating visual cues like circles, arrows, or custom shapes that can enhance communication and clarity. This is particularly useful for tasks like highlighting key passages, identifying areas for revision, or providing feedback in a more intuitive way compared to traditional text-based annotations.

Several React PDF viewer components offer the ability to draw freehand annotations including:

  • Document Solutions for PDF by MESCIUS empowers you to personalize PDFs with freehand drawings for emphasis or feedback.
  • PrizmDoc Viewer by Accusoft offers freehand annotation tools to mark up documents with digital ink, enhancing clarity and communication.
  • Syncfusion PDF Viewer (part of Syncfusion Essential Studio Enterprise) facilitates freehand annotation with digital pen support, allowing for natural and expressive markups.

ReactグリッドアプリにPDFエクスポート機能を装備

7月 15, 2024
ReactアプリケーションからグリッドデータをPDFに直接エクスポートすることで、元のレイアウトとフォーマットを維持しながら、グリッドデータを簡単に配布・表示

Exporting a data grid to PDF captures the grid layout, including columns, rows, and formatting, and transforms it into a universally accessible and easily shareable document. The export creates a static file, retaining the original grid layout and formatting, that can be easily distributed and viewed consistently across different platforms and on any device with a PDF reader. Additionally, PDFs provide a secure format for preserving data integrity and can be protected against unauthorized editing, making them ideal for official documentation and archiving purposes. This functionality enhances collaboration and data dissemination efficiency by simplifying the sharing and printing processes while maintaining the original data structure and presentation.

Several React grid components allow you to export to PDF, including:

  • DevExtreme HTML5 JavaScript Data Grid (part of DevExtreme Complete by DevExpress) enables users to export data grids to PDF in React, preserving layout and formatting.
  • KendoReact Data Grid (part of KendoReact by Telerik) offers React applications seamless PDF export functionality, retaining the structure and design for easy distribution.
  • BestReactGrid facilitates grid data export to PDF format in React applications, maintaining the original layout and style for professional data presentation and collaboration.
  • Ignite UI React Grid (part of Infragistics Ignite UI) streamlines the export of data grids to PDF, ensuring consistent representation of data for secure and accessible sharing.
