用印章标准化 PDF 审核

Stamp annotation support in a PDF Viewer component allows applications to place predefined or custom visual marks, such as “Approved,” “Draft,” or date-based stamps, directly onto PDF pages as non-destructive annotations. For software developers, this capability simplifies the implementation of document review and approval processes by enabling users to apply consistent, repeatable markings without altering the underlying content. It improves traceability and collaboration by making document status and actions immediately visible, supports automation through programmatic stamp placement, and helps maintain document integrity while meeting common business and compliance requirements.

Several .NET PDF viewer components support stamp annotations, including:

• Document Solutions for PDF by MESCIUS lets you add stamp annotations, in the PDF Viewer, to indicate status without content changes.
• XFINIUM.PDF CROSS PLATFORM EDITION allows you to place predefined and custom stamp annotations, through its PDF Viewer, for clear review and approval marking.
• PDFView4NET Windows Forms Edition by PDF4DEV Solutions facilitates applying stamp annotations, helping applications visually communicate decisions without altering files.
• Syncfusion ASP.NET Core PDF Viewer (part of Syncfusion Essential Studio Enterprise) allows you to implement stamp annotation support, enabling consistent status indicators.
