Replaced the old drag-and-drop implementation with a custom solution using mouse events for better control and precision. Added `_isDragging` state and dynamic cursor updates to enhance user feedback during drag operations.
Introduced grab offset calculations to ensure accurate field positioning relative to the pointer. Added `OnEditorMouseUp` to reset the drag state and `GetPageSize` to retrieve page dimensions, defaulting to A4 if unavailable.
Updated `envelope-editor.js` to include `pageNumber` in `getClickCoordsOnPdfPage` and removed the obsolete `getDropCoordsOnPage` function. Enhanced `EditorCoords` to include `PageNumber` for improved page identification.
Introduced drag-and-drop functionality for fields in the PDF editor:
- Added `SenderPdfFieldMoveRequest` record to encapsulate field movement data.
- Enhanced `SenderPdfImageEditor.razor` with drag-and-drop event handlers (`OnFieldDragStart`, `OnPageDropAsync`) and updated field structure.
- Updated `SenderEditorPage.razor` to handle field movement via the `OnMoveFieldAsync` method.
- Improved CSS styles for draggable fields and added a delete button with hover effects.
- Added `getDropCoordsOnPage` function in `envelope-editor.js` to calculate normalized drop coordinates.
These changes improve the user experience by enabling intuitive field placement and management in the PDF editor.
Replaced `DxPdfViewer` with a custom PDF rendering solution in `SenderPdfImageEditor` to improve flexibility and control. Added support for displaying placeholder messages and interactive signature fields. Introduced the `SenderPdfFieldOverlay` record to encapsulate field data.
Updated `SenderEditorPage` logic to manage page counts, image URLs, and field overlays. Added a method to estimate PDF page counts. Refactored field removal logic to use index-based operations.
Enhanced styling in `envelope-viewer.css` for improved layout and responsiveness. Updated localization files with new strings for page labels and placeholders. Adjusted JavaScript selectors in `envelope-editor.js` to support the new rendering approach.
Introduced a new `SenderEditorPage` with a modern UI for managing envelopes, uploading PDFs, and placing signature fields. Integrated `DevExpress.Blazor.PdfViewer` for PDF rendering and interaction.
Key features include:
- PDF upload, rendering, and validation.
- Signature field placement with normalized coordinates.
- Receiver management with validation and email suggestions.
- Envelope metadata handling (title, message).
- Save as draft and send functionality with validation.
- Edit mode for existing envelopes.
- Improved UX with dynamic elements and color-coded receivers.
- Localization support for multi-language UI.
Updated `_Imports.razor` to include necessary namespaces for DevExpress components and the new `PdfEditor` namespace.
