In this article we will see how we can get content rectangle of the image view object in PyQTGaph. 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 movable region defining the dark/light levels, editable gradient provides a color lookup table. Content rectangle is the bounding rectangle of the content of 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 do this we use contentsRect method with the image view object
Syntax : imv.contentsRect()
Argument : It takes no argument
Return : It returns QRect object
Below is the implementation
