Introduction
Dynamsoft Document Viewer (DDV) is a browser-based JavaScript SDK designed for viewing and editing images and PDFs. It provides a wide range of functionalities, including PDF annotation, page manipulation, image quality enhancement, and document saving.
Security
Dynamsoft Document Viewer does not rely on any external third-party JavaScript library. All processing, such as rendering and editing, is securely performed within the browser. This architecture eliminates the need for a server-side backend, ensuring security compliance and scalability.
Browser and Platform Compatibility
Dynamsoft Document Viewer is designed to work seamlessly across different browsers and platforms. It is compatible with major browsers like Chrome, Firefox, Safari, and Edge, ensuring a consistent user experience. Additionally, it supports various operating systems, including Windows, macOS, Linux, iOS, and Android, allowing users to access documents from any device.
Supported File Types
Users can open, edit, and save PDFs, as well as images in various formats, such as JPEG, PNG, and TIFF.
Annotation Types
Dynamsoft Document Viewer supports a variety of annotation types to enhance document interaction and collaboration. Users can add, edit, and delete annotations such as:
- text
- highlight
- underline
- strikeout
- shape
- stamp
- freehand drawing
Data Management Concepts
Dynamsoft Document Viewer organizes data using two main concepts: "document" and "page". A document can contain one or multiple pages, and each page must belong to a single document.
- Page: The smallest unit of data management, currently represented as an image. Each page has a unique pageUid.
- Document: A collection of pages, each with a unique docUid. Documents collectively make up the entire data set. Managing data, therefore, involves managing documents and pages.
If you are using the default UI of DDV, data processing and management are handled internally.
UI Customization
The SDK offers extensive customization options, enabling developers to tailor the UI to meet specific application needs and branding requirements.
Designed to Support Diverse Document Workflows
Dynamsoft Document Viewer is built to support a wide range of document-centric workflows with its document viewing, editing, and scanning features. It has four built-in viewer types to suit different use cases:
- Edit Viewer: Enables viewing and editing of documents with annotation support.
- Capture Viewer: Integrates camera controls for streamlined, continuous capture workflows.
- Perspective Viewer: Allows document cropping with perspective transformation.
- Browse Viewer: Suitable for previewing multi-page documents or navigating document collections.
