Properties

max

• Optional max: number

Maximum number of text regions to return. Default 1000. Recognition stops once this many results are collected.

---

detectRotation

• Optional detectRotation: boolean

Whether to estimate text rotation per line. Default false. When true, results include rotation angle and confidence, at the cost of extra processing time.

Note

Enabling rotation detection increases runtime.

---

region

• Optional region: Region

Restrict recognition to a rectangle in image coordinates. If omitted, the full image is used.

Example

"nodejs";
const { createOCR } = require("ocr");
const cv = require("@autojs/opencv");

async function main() {
  const ocr = await createOCR();
  const img = await readImage("./image.png");

  // Only the top-left 500×500 region
  const results = await ocr.detect(img, {
    region: new cv.Rect(0, 0, 500, 500),
  });

  ocr.release();
}
main();
