Window class

Window is a wrapper around OpenCV's "HighGUI" named windows. While OpenCV was designed for use in full-scale applications and can be used within functionally rich UI frameworks (such as Qt*, WinForms*, or Cocoa*) or without any UI at all, sometimes there it is required to try functionality quickly and visualize the results. This is what the HighGUI module has been designed for.

Constructors

Window(String name, [int flags = 0])

creates a new named OpenCV window

Properties

hashCode → int

The hash code for this object.

no setter, inherited

isOpen → bool

no setter

name ↔ String

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

close() → void

getWindowProperty(WindowPropertyFlags flag) → double

getWindowProperty returns properties of a window.

imshow(Mat img) → void

IMShow displays an image Mat in the specified window. This function should be followed by the WaitKey function which displays the image for specified milliseconds. Otherwise, it won't display the image.

moveWindow(int x, int y) → void

MoveWindow moves window to the specified position.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

resizeWindow(int width, int height) → void

ResizeWindow resizes window to the specified size.

selectROI(Mat img) → Rect

SelectROI selects a Region Of Interest (ROI) on the given image. It creates a window and allows user to select a ROI cvRunArena mouse.

selectROIs(Mat img) → VecRect

SelectROIs selects multiple Regions Of Interest (ROI) on the given image. It creates a window and allows user to select ROIs cvRunArena mouse.

setWindowProperty(WindowPropertyFlags flag, double value) → void

setWindowProperty changes parameters of a window dynamically.

setWindowTitle(String title) → void

SetWindowTitle updates window title.

toString() → String

A string representation of this object.

inherited

waitKey(int delay) → int

WaitKey waits for a pressed key. This function is the only method in OpenCV's HighGUI that can fetch and handle events, so it needs to be called periodically for normal event processing

Operators

operator ==(Object other) → bool

The equality operator.
