Introduced `currentRenderTask` to track and manage rendering tasks, ensuring only one task is active at a time. Added logic to cancel ongoing tasks before starting new ones, preventing conflicts and redundant rendering.
Enhanced error handling to gracefully manage `RenderingCancelledException` and allow rendering of pending pages. Improved logging for better debugging and insights into the rendering process. Ensured clean state management by resetting `currentRenderTask` after task completion or cancellation.
Introduced a new Blazor component `EnvelopeViewer.razor` to display PDF documents with a user-friendly interface. The component supports dynamic routing via `/envelope/{EnvelopeKey}` and integrates the `pdf.js` library for efficient PDF rendering in the browser.
Key features include:
- Zoom and navigation controls (Next/Previous page, Zoom In/Out).
- Loading spinner, error handling, and fallback UI for robustness.
- Responsive design with modern styling using CSS.
- JavaScript interop via `pdf-viewer.js` for managing PDF rendering, scaling, and navigation.
Added lifecycle methods (`OnInitializedAsync`, `OnAfterRenderAsync`) for dynamic loading and rendering. Ensured asynchronous operations for smooth user interactions. Included a `DisposeAsync` method for cleanup.
Introduced a dynamic typing effect for the homepage description using the `Typed` library. Replaced hardcoded description text in `Index.razor` with a dynamically rendered `<span>` element. Added a constant for the description text and implemented `OnAfterRenderAsync` to invoke the typing animation on first render.
Included the `typed.umd.js` library in `index.html` and updated `receiver-signature.js` with a `startTyped` function to support typing animations. Registered `startTyped` in the public API for external use.
Enhanced the user experience with dynamic content rendering and improved maintainability by centralizing the description text. Also added a new theme file for improved styling.
- Added dependency injection for `AnnotationService`, `DocumentService`, and `AuthService` in `ReportViewer.razor`.
- Improved signature button logic with dynamic appearance and feedback.
- Introduced annotation checkbox overlays for marking signature fields.
- Refactored signature saving and application logic into `SaveSignatureAsync` and `SubmitSignaturesAsync`.
- Added `BuildFreshBaseReport` and `AddAnnotationPlaceholders` for dynamic report creation.
- Implemented annotation-specific signature placement with `AddSignatureAtAnnotation`.
- Enhanced state management for annotations and signature overlays.
- Updated `app.css` with styles for annotation checkboxes.
- Added cache-control headers and versioned JavaScript in `index.html`.
- Improved `receiver-signature.js` with annotation checkbox management, optimized signature pad logic, and debugging utilities.
- Performed general code cleanup and optimization for maintainability.
Refactored `@using` directives in `ReportViewer.razor` to use specific aliases for improved readability. Updated the signature popup to support three input modes: "Draw", "Text", and "Image", with a tabbed interface for switching between modes. Added font selection for typed signatures and improved state management for signature modes.
Refactored JavaScript interop methods to handle initialization, clearing, and data retrieval for each signature mode. Enhanced `receiver-signature.js` to support typed and image-based signatures, including rendering text-based signatures and handling image uploads with scaling and centering.
Improved maintainability by modularizing code and extracting reusable functions. Enhanced user experience with dynamic UI updates and better handling of signature state changes.
Introduced a signature input feature in `ReportViewer.razor` to allow users to draw a signature on a canvas and embed it into reports before exporting as a signed PDF.
- Added a canvas (`receiver-signature-pad`) and buttons for clearing, applying, and exporting signatures.
- Injected `IJSRuntime` for JavaScript interop and added methods for signature handling (`ClearSignatureAsync`, `ApplySignatureAsync`, `ExportSignedPdfAsync`).
- Embedded the signature as an image and label in the report's bottom margin.
- Added `receiver-signature.js` to manage the signature pad, including drawing, clearing, and exporting the signature as a Base64 image.
- Updated `index.html` to include the new JavaScript file.
- Displayed validation messages for missing or invalid signatures.
