@defgroup highgui_winrt WinRT support
This figure explains new functionality implemented with WinRT GUI. The new GUI provides an Image control,
and a slider panel. Slider panel holds trackbars attached to it.
Sliders are attached below the image control. Every new slider is added below the previous one.
See below the example used to generate the figure:
@code
void sample_app::MainPage::ShowWindow()
{
static cv::String windowName("sample");
cv::winrt_initContainer(this->cvContainer);
cv::namedWindow(windowName); // not required
cv::Mat image = cv::imread("Assets/sample.jpg");
cv::Mat converted = cv::Mat(image.rows, image.cols, CV_8UC4);
cvtColor(image, converted, CV_BGR2BGRA);
cv::imshow(windowName, converted); // this will create window if it hasn't been created before
