Reading Images With Python – Tkinter
There are numerous tools for designing GUI (Graphical User Interface) in Python such as
JPython, etc where Tkinter is the standard Python GUI library, it provides a simple and efficient way to create GUI applications in Python.
Reading Images With Tkinter
In order to do various operations and manipulations on images, we require Python
Pillow package. If the
Pillow package is not present in the system then it can be installed using the below command.
- In Command prompt:
pip install Pillow
- In Anaconda prompt:
conda install -c anaconda pillow
Example 1: The below program demonstrates how to read images with
In the above program, an image is loaded using the
PhotoImage() method and then it is read by using the
pack() method arranges the main window and the
mainloop() function is used to run the application in an infinite loop.
Example 2: Let us look at another example where we arrange the image parameters along with application parameters.
In the above program, the application parameters are handled by using the
Canvas() method and the image parameters are handled using
create_image() method such that the image
gfg.ppm is displayed in the main window having defined height and width.
Note: The Canvas method create_image(x0,y0, options …) is used to draw an image on a canvas. create_image doesn’t accept an image directly. It uses an object which is created by the PhotoImage() method. The PhotoImage class can only read GIF and PGM/PPM images from files.
