PyQtGraph – Getting Children Region of Image View
In this article, we will see how we can get children region of the image view object in PyQTGraph. The PyQtGraph is a graphics and user interface library for Python that provides functionality commonly required in designing and science applications. Its primary goals are to provide fast, interactive graphics for displaying data (plots, video, etc.), widget used for display and analysis of image data, implements many features like displaying 2D and 3D image data. For 3D data, a z-axis slider is displayed allowing the user to select which frame is displayed. Displays histogram of image data with a movable region defining the dark/light levels, editable gradient provides a color lookup table. Image view is a group of widgets like it contains a view object, push-button and scroll bars, children region is the region occupied by the children of the image view.
We can create an image view with the help of command given below:
# creating a pyqtgraph image view object imv = pg.ImageView()
In order to get children region of an Image View, we use childrenRegion() method with the image view object.
Syntax : imv.childrenRegion()
Argument : It takes no argument
Return : It returns QRegion object
Below is the program to get children region of an Image View using PyQTGraph module:
