# libtransform Skill

## When to Use

- Converting PDF documents to HTML
- Extracting content from scanned documents
- Processing documents with LLM vision models
- Building document transformation pipelines

## Key Concepts

**pdfToHtml**: Splits PDF into page images, sends to vision-capable LLM, and
assembles HTML output with semantic structure.

## Usage Patterns

### Pattern 1: Convert PDF to HTML

```javascript
import { pdfToHtml } from "@copilot-ld/libtransform";

const pdfBuffer = await fs.readFile("document.pdf");
const html = await pdfToHtml(pdfBuffer, {
  model: "gpt-4-vision-preview",
  maxPages: 50,
});
```

## Integration

Used by libingest pipeline for document processing. Requires LLM with vision
capabilities.
