autojs提取指定颜色的文字区域

  let mat2 = mat.clone();
  // opencv是bgr, autojs是rgb, 需要转换颜色
  Imgproc.cvtColor(mat, mat2, Imgproc.COLOR_BGRA2RGBA);
  Imgproc.rectangle(
    mat2,
    new Point(area.left, area.top),
    new Point(area.right, area.bottom),
    new Scalar(0, 255, 0, 255),
    2
  );
  log(area);
  viewMat(mat2);

function viewMat(mat) {
  let mat2 = mat.clone();
  Imgproc.cvtColor(mat, mat2, Imgproc.COLOR_BGRA2RGBA);
  let tempFilePath = files.join(files.getSdcardPath(), "脚本", "mat.png");
  Imgcodecs.imwrite(tempFilePath, mat2);
  mat2.release();
  app.viewFile(tempFilePath);
}
