允许用户直接标记 PDF 文件

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.
