Introduction
If you are looking to split images into multiple pieces, Python is a great programming language to do so. In this tutorial, we will take you through the step-by-step process of splitting an image into multiple pieces in just 10 steps. This tutorial is perfect for beginners and advanced Python developers alike.
What You Will Need
Before we start, make sure you have Python 3 installed on your computer. You will also need the following libraries:
| Library Name | Version |
|---|---|
| Pillow | 7.0.0 or later |
| Numpy | 1.18.1 or later |
Step 1: Import Required Libraries
The first step is to import the required libraries. We need the Pillow library for opening and manipulating images, and NumPy for converting the image into a NumPy array. Here is the code to import the required libraries:
“`pythonfrom PIL import Imageimport numpy as np“`
Step 2: Load the Image
In this step, we will load the image that we want to split into pieces. We will use the `Image.open()` method of the Pillow library to open the image. Here is the code to load the image:
“`pythonimage = Image.open(your_image.jpg)“`
Step 3: Convert the Image to a NumPy Array
Now, we need to convert the image into a NumPy array so that we can easily manipulate it. We will use the `np.array()` method of the NumPy library to convert the image into an array. Here is the code to convert the image:
“`pythonimage_array = np.array(image)“`
Step 4: Calculate the Dimensions of Each Piece
In this step, we will calculate the dimensions of each piece that we want to split the image into. We need to specify the number of rows and columns that we want the image to be split into. Here is the code to calculate the dimensions:
“`pythonrows = 4cols = 4height, width, channels = image_array.shapepiece_height = int(height / rows)piece_width = int(width / cols)“`
Step 5: Split the Image into Pieces
Now, we will split the image into pieces using the dimensions calculated in the previous step. We will use a loop to iterate through each row and column and extract the corresponding piece from the image. Here is the code to split the image:
“`pythonpieces = []for r in range(rows): for c in range(cols): x1 = c * piece_width y1 = r * piece_height x2 = x1 + piece_width y2 = y1 + piece_height piece = image_array[y1:y2, x1:x2] pieces.append(piece)“`
Step 6: Save the Pieces to Disk
We have now successfully split the image into multiple pieces. In this step, we will save each piece to disk as a separate image. We will use the `Image.fromarray()` method of the Pillow library to create an image from each piece and save it to disk using the `save()` method. Here is the code to save each piece to disk:
“`pythonfor i, piece in enumerate(pieces): piece_image = Image.fromarray(piece) piece_image.save(fpiece_{i}.jpg)“`
Step 7: Display a Single Piece
Now that we have split the image into pieces and saved them to disk, we can display a single piece to make sure that it has been correctly extracted. We will use Matplotlib to display the piece. Here is the code to display a single piece:
“`pythonimport matplotlib.pyplot as pltplt.imshow(pieces[0])plt.show()“`
Step 8: Display All Pieces
We can also display all the pieces together to see how the original image has been split into multiple pieces. We will use Matplotlib to display all the pieces. Here is the code to display all the pieces:
“`pythonfig, axs = plt.subplots(rows, cols, figsize=(10,10))for r in range(rows): for c in range(cols): axs[r][c].imshow(pieces[r*rows+c])plt.show()“`
Step 9: Conclusion
We have successfully split an image into multiple pieces using Python and the Pillow and NumPy libraries. This tutorial is a great starting point if you are looking to work with images in Python.
Step 10: Additional Resources

Table Comparison
| Steps | Java | Python |
|---|---|---|
| Import Required Libraries | import java.awt.image.BufferedImage; | from PIL import Image import numpy as np |
| Load the Image | BufferedImage image = ImageIO.read(new File(your_image.jpeg)); | image = Image.open(your_image.jpg) |
| Convert the Image to a 2D Array | – | image_array = np.array(image) |
| Calculate the Dimensions of Each Piece | – | rows = 4 cols = 4 height, width, channels = image_array.shape piece_height = int(height / rows) piece_width = int(width / cols) |
| Split the Image into Pieces | – | pieces = [] for r in range(rows): for c in range(cols): x1 = c * piece_width y1 = r * piece_height x2 = x1 + piece_width y2 = y1 + piece_height piece = image_array[y1:y2, x1:x2] pieces.append(piece) |
| Save the Pieces to Disk | File output_file = new File(output_image.jpeg); ImageIO.write(piece, jpeg, output_file); |
for i, piece in enumerate(pieces): piece_image = Image.fromarray(piece) piece_image.save(fpiece_{i}.jpg) |
| Display a Single Piece | – | import matplotlib.pyplot as plt plt.imshow(pieces[0]) plt.show() |
| Display All Pieces | – | fig, axs = plt.subplots(rows, cols, figsize=(10,10)) for r in range(rows): for c in range(cols): axs[r][c].imshow(pieces[r*rows+c]) plt.show() |
