# Scipix WASM - WebAssembly OCR
|
||||
|
||||
High-performance OCR with LaTeX support for the browser, powered by WebAssembly.
|
||||
|
||||
## Features
|
||||
|
||||
- 📸 **Image OCR**: Recognize text from images
|
||||
- 🧮 **LaTeX Support**: Extract mathematical formulas
|
||||
- ⚡ **Web Workers**: Off-main-thread processing
|
||||
- 🎯 **TypeScript**: Full type definitions
|
||||
- 🚀 **Optimized**: <2MB bundle size
|
||||
- 🔧 **Flexible API**: Multiple input formats
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Installation
|
||||
|
||||
```bash
|
||||
npm install ruvector-scipix-wasm
|
||||
```
|
||||
|
||||
### Build from Source
|
||||
|
||||
```bash
|
||||
cd examples/scipix
|
||||
npm run build
|
||||
```
|
||||
|
||||
### Basic Usage
|
||||
|
||||
```javascript
|
||||
import { createScipix } from 'ruvector-scipix-wasm';
|
||||
|
||||
// Initialize
|
||||
const scipix = await createScipix();
|
||||
|
||||
// Recognize from file
|
||||
const result = await scipix.recognize(imageData);
|
||||
console.log(result.text);
|
||||
console.log(result.latex);
|
||||
```
|
||||
|
||||
### Canvas Example
|
||||
|
||||
```javascript
|
||||
import { recognizeCanvas } from 'ruvector-scipix-wasm';
|
||||
|
||||
const canvas = document.getElementById('myCanvas');
|
||||
const result = await recognizeCanvas(canvas);
|
||||
```
|
||||
|
||||
### Web Worker Example
|
||||
|
||||
```javascript
|
||||
import { createWorker } from 'ruvector-scipix-wasm';
|
||||
|
||||
const worker = createWorker();
|
||||
|
||||
// Process in background
|
||||
const result = await worker.recognize(imageData);
|
||||
|
||||
// Batch processing with progress
|
||||
const results = await worker.recognizeBatch(images, {
|
||||
onProgress: ({ processed, total }) => {
|
||||
console.log(`Progress: ${processed}/${total}`);
|
||||
}
|
||||
});
|
||||
|
||||
worker.terminate();
|
||||
```
|
||||
|
||||
## API Reference
|
||||
|
||||
### `createScipix(options?)`
|
||||
|
||||
Create a new Scipix instance.
|
||||
|
||||
```typescript
|
||||
const scipix = await createScipix({
|
||||
format: 'both', // 'text' | 'latex' | 'both'
|
||||
confidenceThreshold: 0.5 // 0.0 - 1.0
|
||||
});
|
||||
```
|
||||
|
||||
### `ScipixWasm`
|
||||
|
||||
Main API class.
|
||||
|
||||
#### Methods
|
||||
|
||||
- `recognize(imageData: Uint8Array): Promise<OcrResult>`
|
||||
- `recognizeFromCanvas(canvas: HTMLCanvasElement): Promise<OcrResult>`
|
||||
- `recognizeBase64(base64: string): Promise<OcrResult>`
|
||||
- `recognizeImageData(imageData: ImageData): Promise<OcrResult>`
|
||||
- `recognizeBatch(images: Uint8Array[]): Promise<OcrResult[]>`
|
||||
- `setFormat(format: RecognitionFormat): void`
|
||||
- `setConfidenceThreshold(threshold: number): void`
|
||||
- `getVersion(): string`
|
||||
|
||||
### Helper Functions
|
||||
|
||||
```javascript
|
||||
import {
|
||||
recognizeFile, // From File/Blob
|
||||
recognizeCanvas, // From HTMLCanvasElement
|
||||
recognizeBase64, // From base64 string
|
||||
recognizeUrl, // From image URL
|
||||
recognizeBatch, // Batch processing
|
||||
imageToCanvas, // Convert image to canvas
|
||||
} from 'ruvector-scipix-wasm';
|
||||
```
|
||||
|
||||
## Types
|
||||
|
||||
### `OcrResult`
|
||||
|
||||
```typescript
|
||||
interface OcrResult {
|
||||
text: string; // Recognized text
|
||||
latex?: string; // LaTeX (if enabled)
|
||||
confidence: number; // 0.0 - 1.0
|
||||
metadata?: {
|
||||
width?: number;
|
||||
height?: number;
|
||||
format?: string;
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### `RecognitionFormat`
|
||||
|
||||
```typescript
|
||||
type RecognitionFormat = 'text' | 'latex' | 'both';
|
||||
```
|
||||
|
||||
## Demo
|
||||
|
||||
Run the interactive demo:
|
||||
|
||||
```bash
|
||||
npm run dev
|
||||
```
|
||||
|
||||
Open http://localhost:8080/example.html
|
||||
|
||||
## Performance Tips
|
||||
|
||||
1. **Use Web Workers** for large images or batch processing
|
||||
2. **Set confidence threshold** to filter low-quality results
|
||||
3. **Resize images** before processing if possible
|
||||
4. **Reuse instances** instead of creating new ones
|
||||
5. **Use SharedImageBuffer** for large image batches
|
||||
|
||||

||||
- Chrome 57+
|
||||
- Firefox 52+
|
||||
