Hello there,

slope

Does anybody know of a tool, library, or whatever on Python that allows you to create/access a user interface where the user could modify an image by drawing over it (something like Paint)?

Any help would be much appreciated!

This was created by Google AI (tested and works):

import tkinter as tk

class PaintApp:
    def __init__(self, master):
        self.master = master
        master.title("Simple Paint")

        self.canvas_width = 600
        self.canvas_height = 400
        self.canvas = tk.Canvas(master, width=self.canvas_width, height=self.canvas_height, bg="white")
        self.canvas.pack()

        self.pen_color = "black"
        self.pen_size = 2
        self.drawing_tool = "pen"
        self.last_x, self.last_y = None, None

        self.canvas.bind("<B1-Motion>", self.draw)
        self.canvas.bind("<ButtonRelease-1>", self.reset_coords)

        self.create_controls()

    def create_controls(self):
        controls_frame = tk.Frame(self.master)
        controls_frame.pack()

        color_label = tk.Label(controls_frame, text="Color:")
        color_label.pack(side=tk.LEFT)

        colors = ["black", "red", "blue", "green", "yellow"]
        for color in colors:
            color_button = tk.Button(controls_frame, bg=color, width=2, command=lambda c=color: self.set_color(c))
            color_button.pack(side=tk.LEFT)

        size_label = tk.Label(controls_frame, text="Size:")
        size_label.pack(side=tk.LEFT)

        sizes = [2, 5, 8, 10]
        for size in sizes:
            size_button = tk.Button(controls_frame, text=str(size), command=lambda s=size: self.set_size(s))
            size_button.pack(side=tk.LEFT)
    
    def draw(self, event):
         x, y = event.x, event.y
         if self.last_x is not None and self.last_y is not None:
            if self.drawing_tool == "pen":
                self.canvas.create_line(self.last_x, self.last_y, x, y, fill=self.pen_color, width=self.pen_size, capstyle=tk.ROUND, smooth=tk.TRUE)
         self.last_x, self.last_y = x, y

    def reset_coords(self, event):
        self.last_x, self.last_y = None, None
        
    def set_color(self, color):
        self.pen_color = color

    def set_size(self, size):
        self.pen_size = size

root = tk.Tk()
app = PaintApp(root)
root.mainloop()

You can use Tkinter with PIL (Pillow) to create a simple drawing tool in Python, or go for PyQt for a more advanced UI. If you're looking for something pre-built, OpenCV also allows basic drawing functionalities with mouse events. Check out Tkinter's Canvas for a lightweight option!
