Python | Adding image in Kivy using .kv file
Kivy is a platform independent GUI tool in Python. As it can be run on Android, IOS, linux, and Windows, etc. It is basically used to develop the Android application, but it does not mean that it can not be used on Desktops applications.
The Image widget is used to display an image. To use the image widget you must have to import :
from kivy.uix.image import Image, AsyncImage (not necessary while working with .kv file)
because the module kivy.uix.image have all the functionality related to images.
Images can be loaded to the Application via two types:
1) Synchronous Loading: Loading image from the system (must be from the folder in which .py and .kv file is saved)
2) Asynchronous Loading: To load an image asynchronously (for example from an external webserver)
Note: By default, the image is centered and fits inside the widget bounding box. If you don’t want that, you can set allow_stretch to True and keep_ratio to False.
Basic Approach to create multiple layout in one file: 1) import kivy 2) import kivyApp 3) import image 4) import BoxLayout 5) set minimum version(optional) 6) Create the Layout class 7) Create App class 8) Create .kv file: 1) Add BoxLayout 2) Add Label 3) Add Image 4) Resizing, Positioning etc of Image 9) return instance of the layout class 10) Run an instance of the class
So in the below code, we will explain How to load Synchronous and Asynchronous images. Also How to resize, Positioning, Label, etc the image with some more stuff.
