## Demo

The hosted demo at the root URL of this site is a single-page Laravel 12 host app that lazy-seeds a guest user, a sample 3-page PDF, and a workspace on first visit. Visitors fill a short "Get Started" form (name, phone, email, project need) which unlocks an interactive viewer session in the same browser and emails a personal demo link.

## Key capabilities

- PDF.js viewer with native-feeling scroll, zoom, and search
- Six annotation types: highlight, note (free-text), pin, region, excerpt (pull text onto a canvas), link
- Workspace canvas with free-form pen, pressure support (Apple Pencil), free-floating text boxes
- Per-document notepad
- Signer-link e-signature: owner mints a one-time signed URL; recipient signs in a sign-only viewer; stamps + audit trail saved back through Eloquent
- Multi-PDF merge upload
- Office-to-PDF conversion via LibreOffice headless (doc, docx, xls, xlsx, ppt, pptx, odt, ods, odp, rtf, txt) — opt-in
- Annotated PDF export
- Signed sharing URLs
- Iframe + postMessage events for host SPAs (page changes, annotation events, go-to-page commands)
- Owner-scoped records gated by a Laravel policy hook the host app controls

## Architecture quick map

- All viewer routes live under `/doccanvas/*` and are registered by the package's service provider.
- Storage uses any Laravel filesystem disk (defaults to the configured `doccanvas.storage.disk`).
- Annotations, signatures, workspaces, grants, tenants, and license events live in their own migrations published by the package.
- Office conversion uses a driver pattern: `libreoffice` (default if `soffice` is present) or `disabled`.
- The host app supplies authentication; the package never ships its own login pages.

## Install (after purchase)

```bash
composer require aim/laravel-doccanvas
php artisan vendor:publish --tag=doccanvas-config
php artisan vendor:publish --tag=doccanvas-assets
php artisan migrate
php artisan storage:link
```

## FAQs

**Q: Which Laravel versions does DocCanvas support?**
A: Laravel 11 and 12 on PHP 8.2 or newer. The service provider is auto-discovered.

**Q: Does DocCanvas need a separate PDF rendering service?**
A: No. PDF rendering happens in the browser through PDF.js. Office-to-PDF conversion runs server-side through LibreOffice when enabled.

**Q: Where are annotations stored?**
A: In your own database through Eloquent models shipped with the package.

**Q: Can I embed the viewer inside Angular, React, or Vue?**
A: Yes. The viewer is iframe-ready and emits page and annotation events through postMessage; the host app can push go-to-page commands back.

**Q: How does the e-signature flow work?**
A: The document owner generates a one-time signer link. The recipient opens a sign-only viewer through a signed URL; signature stamps and the audit trail are written back against the document.

**Q: Is DocCanvas open source?**
A: No. It's a commercial Laravel package distributed through a private Composer registry. Contact info@aiminfosoft.com for pricing.

**Q: Is there a refund?**
A: A 14-day refund applies if the package does not work for your project. Email info@aiminfosoft.com.
