getRectSubPixAsync function

Future<Mat> getRectSubPixAsync(
  1. InputArray image,
  2. (int, int) patchSize,
  3. Point2f center, {
  4. OutputArray? patch,
  5. int patchType = -1,
})

GetRectSubPix retrieves a pixel rectangle from an image with sub-pixel accuracy.

Implementation

Future<Mat> getRectSubPixAsync(
  InputArray image,
  (int, int) patchSize,
  Point2f center, {
  OutputArray? patch,
  int patchType = -1,
}) {
  patch ??= Mat.empty();
  return cvRunAsync0(
    (callback) => cimgproc.cv_getRectSubPix(image.ref, patchSize.cvd.ref, center.ref, patch!.ref, callback),
    (c) {
      return c.complete(patch);
    },
  );
}
