 ## API

-### `processPdfWithOcr(buffer: Buffer, options?: OcrOptions): Promise<OcrPdfResult>`
-
-Run native extraction first and OCR only the pages selected by its quality
-signals. The default mode is `Auto`; `Off` returns the same detailed result
-shape without external runtime work, and `Force` OCRs every selected page.
-The work runs on the libuv thread pool and never blocks Node's event loop.

-```typescript
-import { OcrMode, processPdfWithOcr } from '@firecrawl/pdf-inspector'
-
-const result = await processPdfWithOcr(pdf, {
-  mode: OcrMode.Auto,
-  pageNumbers: [1, 3], // 1-indexed

-console.log(result.pagesRoutedToOcr)
-console.log(result.pagesRecommendingHosted)

-controls include `dpi`, `minimumConfidence`,
-`hostedRecommendationConfidence`, and `password`.
