快速刪除過時的註釋，以保持文件清晰、相關，併為最終演示或存檔做好準備。

Annotation removal is a useful feature to have in a PDF viewer component, giving users the ability to delete comments, highlights, notes, or other markup that has been added to a PDF document. This functionality allows users to clean up documents by eliminating unnecessary or outdated annotations, ensuring that only relevant and current information remains visible. It is particularly useful in collaborative environments where multiple reviewers contribute feedback, and improves the presentation of the final document, ensuring it is clear and professional. This process yields a clean version of the file in preparation for final distribution or archiving.

Several JavaScript PDF viewer components allow you to remove annotations, including:

  • Kendo UI PDF Viewer for jQuery (part of Kendo UI by Telerik) allows you to delete annotations easily, helping maintain the clarity and readability of PDFs.
  • PrizmDoc Viewer (part of PrizmDoc by Accusoft) facilitates the removal of annotations, enabling users to present polished PDF content after collaborative review.
  • Syncfusion PDF Viewer (part of Syncfusion Essential Studio Enterprise) provides users with a simple way to prepare PDFs for final delivery by enabling them to clear annotations.

Watermarks in PDFs are semi-transparent text or image overlays that serve as a security and branding tool by marking documents with identifying information. They help protect intellectual property, prevent unauthorized distribution, and reinforce authenticity by displaying ownership, confidentiality, or document status (e.g., "Draft," "Confidential," or "Approved"). Watermarking also enhances professionalism by incorporating company logos or copyright notices. Common use cases include securing legal contracts, corporate reports, research papers, and sensitive business documents to ensure proper handling and compliance. By integrating customizable watermarking, organizations can maintain control over their digital documents while preserving readability and usability.

Several .NET WPF PDF components allow you to add watermarks, including:

  • Syncfusion WPF PDF (part of Syncfusion Essential Studio Enterprise) lets you add customizable watermarks to PDFs, enhancing security, branding, and document control.
  • Telerik UI PDF for WPF (part of Telerik UI for WPF) enables dynamic watermarking in PDFs, ensuring confidentiality, copyright protection, and professional branding.
