Python implements flood filling algorithm class (with complete source code)

Flood Fill algorithm (Flood Fill) is an image processing algorithm that fills all areas with the same color as the starting point with the specified target color by specifying a starting point and a target color. In this post, we will implement the flood fill algorithm in Python and provide the full source code.

First, we need to import the Image module and ImageDraw module for image processing and drawing operations.

from PIL import Image
from PIL import ImageDraw

Then, we create a FloodFill class that contains the following methods:

• __init__(self, image_path): Initialization method, used to load pictures.
• get_image(self): Returns the current image object.
• set_pixel(self, x, y, color): Set the pixel color at the specified position.
• get_pixel(self, x, y): Get the pixel color at the specified location.
• flood_fill(self, x, y, fill_color): The implementation method of the flood filling algorithm.
