Avril 9, 2025
Améliorez les applications .NET avec une visionneuse PDF qui permet la conversion des feuilles de calcul Microsoft Excel en fichiers PDF pour une plus grande accessibilité.

A .NET PDF viewer with Excel to PDF conversion capabilities enables developers to augment their .NET-based applications so that users can transform Microsoft Excel spreadsheets (in XLSX or XLS format) into PDF documents for viewing, sharing, or archiving.

Les annotations PDF sous forme de post-it permettent de joindre des informations aux fichiers PDF pour améliorer la collaboration et simplifier la révision des documents sans en modifier le contenu.

For developers, it offers a straightforward way to integrate lightweight commenting functionality into document-centric applications, enhancing usability and facilitating more efficient communication among users.

Mars 25, 2025
Ajoutez facilement des filigranes personnalisables aux PDF pour renforcer la sécurité des documents, protéger la propriété intellectuelle et accroître votre image de marque.

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:
