Rectangle annotations in PDF viewer components enable users to highlight, mark, or comment on specific areas within a PDF document by drawing rectangular shapes. This feature is commonly used for reviewing documents, collaborating on content, or emphasizing sections in technical or legal workflows. It enhances user interactivity within the viewer, allowing for visual references and context-specific notes without altering the original document content.

Several React PDF viewer controls offer rectangle annotations including:

  • Document Solutions for PDF by MESCIUS provides rectangle annotations as part of its comprehensive annotation API, supporting precise placement and customization.
  • PrizmDoc Viewer by Accusoft includes rectangle annotations within its markup and redaction tools, offering collaborative editing capabilities with server-side processing.
  • Syncfusion PDF Viewer (part of Syncfusion Essential Studio Enterprise) supports interactive rectangle annotations through its built-in annotation toolbar.
