Description

if i write this:

  cv::Mat img(1024, 1024, CV_8UC4, cv::Scalar(255, 255, 255, 255));
  cv::line(img, cv::Point2i(90, 50), cv::Point2i(100, 100), cv::Scalar(0, 0, 0, 255), 1, CV_AA);

then i see only white image, but if i write this:

  cv::line(img, cv::Point2i(90, 50), cv::Point2i(100, 100), cv::Scalar(0, 0, 0, 255), 1);

then it's work but with antialiasing.
