In this article, we will see how we can set a custom cursor to 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 a movable region defining the dark/light levels, editable gradient provides a color lookup table. In computer user interfaces, a cursor is an indicator used to show the current position for user interaction on a computer monitor or other display device that will respond to input from a text input or pointing device. The mouse cursor is also called a pointer, owing to its resemblance in usage to a pointing stick.
We can create an image view with the help of the command given below
# creating a pyqtgraph image view object imv = pg.ImageView()
In order to do this we use setCursor method with the image view object
Syntax : imv.setCursor(cursor)
Argument : It takes QCursor object as argument
Return : It returns None
Below is the implementation
