Customizable Annotation Types
This module allows users to create and apply custom annotation types such as highlights, comments, stamps, and notes. Annotations can be configured with specific colors, shapes, and text formatting to suit various use cases.
Integration with External Systems
The tool provides APIs for seamless integration with external systems, enabling developers to automate document processing workflows and extend functionality to third-party applications.
Batch Processing Capabilities
Users can process multiple documents simultaneously, making it efficient for large-scale operations. This feature is particularly useful for automating repetitive tasks in development environments.
Real-time Collaboration
Multiple users can annotate the same document in real-time without conflicts. Changes are reflected instantly across all connected devices, promoting teamwork and efficiency.
Search and Filter Annotations
Annotations can be searched or filtered based on keywords, metadata, or other criteria. This feature enhances usability by allowing developers to quickly locate specific annotations within large documents.
Version Control Integration
The module integrates with version control systems like Git, enabling tracking of document changes over time. This is crucial for maintaining a history of annotations and ensuring accountability in collaborative environments.
Export/Import Annotations
Annotations can be exported in various formats (e.g., JSON) and imported back into the system. This feature is useful for migrating annotations between different instances or systems.
Security and Access Control
The tool includes role-based access control, allowing developers to restrict document access and annotation permissions to specific users or groups. Data encryption ensures sensitive information remains protected.
Support for Multiple File Formats
The module supports a wide range of file formats, including PDF, Word, PowerPoint, Excel, and image files. This makes it versatile for handling different types of documents in various development scenarios.
API Monitoring and Analytics
Developers can monitor API usage and track key metrics such as request volume, response times, and error rates. This helps optimize performance and troubleshoot issues effectively.

Overview
The Document Annotation Tool is a module designed to allow developers to add annotation capabilities to their applications. It enables users to highlight or comment on PDFs and other document types.
API Endpoints (FastAPI)
Create Annotation Endpoint
This endpoint creates a new annotation for a document.
Endpoint: /api/annotations
Method: POST
Request Body:
{
"document_id": str,
"annotator_name": str,
"annotations": [
{
"id": str,
"coordinates": List[float],
"text": str,
"color": str,
"comment": str
}
]
}
Example Request:
POST /api/annotations HTTP/1.1
Content-Type: application/json
{
"document_id": "12345",
"annotator_name": "John Doe",
"annotations": [
{
"id": "abc123",
"coordinates": [10, 20, 30, 40],
"text": "Important point",
"color": "#FF0000",
"comment": "This is a key insight"
}
]
}
Response:
{
"message": "Annotation created successfully",
"annotation_id": "abc123"
}
React UI Component
AnnotationForm Component
A simple React component that allows users to create and view annotations.
import React, { useState } from 'react';
interface Annotation {
id: string;
coordinates: number[];
text: string;
color: string;
comment: string;
}
export default function AnnotationForm() {
const [selectedFile, setSelectedFile] = useState<File | null>(null);
const [annotations, setAnnotations] = useState<Annotation[]>([]);
const [preview, setPreview] = useState<string>('');
const handleFileSelect = (event: React.ChangeEvent<HTMLInputElement>) => {
const file = event.target.files?.[0];
if (file) {
setSelectedFile(file);
const reader = new FileReader();
reader.onloadend = () => {
setPreview(reader.result as string);
};
reader.readAsDataURL(file);
}
};
const addAnnotation = () => {
// Add annotation logic here
};
return (
<div className="annotation-form">
