How do i draw in python - Create Paint Tool using Python

Published February 07, 2022

In this python example, we will create a simple painting tool using Python. Using this drawing tool, we will be able to draw an image or write a text by moving the cursor. To create this tool, we are going to use the Python Tkinter Library, which is the pre-installed library for creating GUI applications.

 

How to create a paint tool using Python

Below are the steps to create a Python paint tool.

Step 1: Add the following code to your application to import the Tkinter library:

from tkinter import *

Step 2: Create a canvas on the window and set its dimensions.

root.title("Python Paint Tool") root.geometry("500x350") wn=Canvas(root, width=500, height=350, bg='white')

Running this code will display an empty Tkinter canvas window

However, you cannot draw on this canvas windows. We'll create the main function that enables drawing in the next step.

 

Step 3: Create a function  to get the mouse movement  with  the four coordinates, X1,y1, X2, y2 and display it in canvas

def paint(event):         # get x1, y1, x2, y2 co-ordinates         x1, y1 = (event.x-3), (event.y-3)         x2, y2 = (event.x+3), (event.y+3)         color = "black"         # display the mouse movement inside canvas         wn.create_oval(x1, y1, x2, y2, fill=color, outline=color)

 

 

Step 4: We must now bind the main function to the cursor movement

 

wn.bind('<B1-Motion>', paint) wn.pack()

 

 

Step 5: Now run  the paint tool. Now. we can draw or write on the window with the paint tool

 

Complete example code for Draw in python using python paint tool

from tkinter import * root = Tk() root.title("Python Paint Tool") root.geometry("500x350") def paint(event):         x1, y1 = (event.x-3), (event.y-3)         x2, y2 = (event.x+3), (event.y+3)         color = "black"         wn.create_oval(x1, y1, x2, y2, fill=color, outline=color) wn=Canvas(root, width=500, height=350, bg='white') wn.bind('<B1-Motion>', paint) wn.pack() root.mainloop()

Output

 

Conclusion: In this python example we created simple pain tool using Tkinter and draw on the canvas
