 Hello friends! Welcome to the last post on Image Editing Software. In this post, you will be learning how to apply color filters to an image. We will be doing this using the OpenCV library package. You can also check out the video below.  So let's get started. We will start by importing Opencv and Numpy to our code.  import cv2 import numpy as np And now we will start writing the callback methods for applying filters. Let us start with the  yellowButton_callback() method.  def yellowButton_callback (): opencvImage = cv2.cvtColor(np.array(originalImage) , cv2.COLOR_RGB2BGR) opencvImage[: , : , 0 ] = 20 global outputImage outputImage = Image.fromarray(cv2.cvtColor(opencvImage , cv2.COLOR_BGR2RGB)) dispayImage(outputImage) Alright. Let us understand the above code line by line. To apply a color filter I have to manipulate the image array. So I need the image in an array form. np.array(originalImage) converts the image that we read using the PI...

Hello Friends! We are going to develop an Image Editing Software in python. We will be using various libraries like Tkinter, PIL, and OpenCV. We will be developing several features like brightness adjustment, contrast adjustment, applying various filters on the image, etc. So why wait? Let's get started. Make sure to check out the video below before starting. We will start by designing the GUI and later on, we will add the required functionalities to it for image editing. In this tutorial, we will be creating a window that will hold 3 buttons(Import, Save, Close). To create the GUI we will start by importing the Tkinter in our python file as shown below. import tkinter as tk To create a window we will have to call a method called tk.Tk(). window = tk.Tk() So the window is ready. But if you run the above code, you won't see anything appearing on the screen. This is because the program has finished execution. You will have to add a loop to hold the window on the screen. For that,...
