Features Covered in This Repository

Loading Encrypted PDF Documents

This sample demonstrates how to load password-protected or encrypted PDF documents using the Syncfusion PDF Viewer. Encrypted PDFs are commonly used to protect confidential information, and this feature allows applications to provide passwords programmatically while loading the document.

Key aspects demonstrated:

  • Loading encrypted PDF files
  • Providing passwords securely
  • Handling incorrect or missing passwords gracefully

This feature is especially useful for enterprise and security-focused applications.

Setting Minimum Zoom Percentage

This feature demonstrates how to restrict the minimum zoom level of a PDF document. Limiting zoom prevents users from zooming out excessively and helps maintain readability.

Key aspects demonstrated:

  • Setting a minimum zoom factor programmatically
  • Ensuring consistent document layout
  • Improving usability for forms and reports

Displaying PDF Documents in Single Page Mode

This sample demonstrates how to configure the PDF Viewer to display documents one page at a time instead of using continuous scrolling. Single-page mode improves focus and navigation for specific document types.

Key aspects demonstrated:

  • Enabling single-page view mode
  • Navigating between pages
  • Improving reading experience for presentations and educational materials

Prerequisites

Before running the samples, ensure you have the following:

  • Visual Studio with Xamarin workload installed
  • A valid Syncfusion license
  • Basic knowledge of Xamarin.Forms development

Conclusion

This repository serves as a practical reference for developers who want to explore and implement the features introduced in the 2019 Volume 3 release of the Syncfusion Xamarin.Forms PDF Viewer. The samples demonstrate how to work with encrypted documents, control zoom behavior, and customize page viewing modes while maintaining cross-platform consistency.
