PyQtGraph – Removing Mask of Image View
In this article, we will see how we can remove the mask 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 a movable region defining the dark/light levels, editable gradient provides a color lookup table. Mask basically hides the selected part of the image view, the image view will be still there but the user will not be able to see it i.e there will be a mask on it. Only the selected region will be visible other regions will have a mask, it can be set with the help of the setback method.
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 clearMask method with the image view object
Syntax : imv.clearMask()
Argument : It takes no argument
Return : It returns None
Below is the implementation.
