Added a print button to the PDF viewer for direct printing. Implemented a scripting manager to handle XFA forms, ensuring proper rendering and interaction. Updated form-filler logic to support XFA detection and improved error handling for unsupported save operations. Refactored file handling to streamline PDF loading and viewer initialization.
Use original file bytes instead of saved PDF doc to preserve XFA streams. This ensures PDF.js can fully render XFA-based forms by also enabling the XFA flag in the viewer.
Add initial set of PDF.js viewer files including:
- WASM binaries for PDF rendering
- Standard fonts and CMAP files for text rendering
- UI icons and SVG assets for toolbar buttons
- TypeScript declaration files
- Loading animation GIF
- Annotation icons and UI elements
This provides the base functionality for the PDF viewer including:
- Document rendering
- Navigation controls
- Zoom functionality
- Page display options
- Annotation tools
- Document properties
