How to crop an image in Java

In this article, I will show you how to crop an image in Java using just ImageIO or JDeli.

Crop an image in Java with:

ImageIO

1. Load the image file using Java ImageIO (which is built into Java)

   BufferedImage image = ImageIO.read(new File("C:\\path\\to\\kitten.jpg"));

2. Get a cropped version (x, y, width, height) (0,0 is top left corner)

   BufferedImage crop = image.getSubimage(0,0, 100, 100);

3. Save the image back to a File

   ImageIO.write(crop, "JPEG", new File("C:\\path\\to\\picture.jpeg"));

Note it is important to save the image before applying any other changes as the BufferedImage object is shared between the original and new crop object.

JDeli

1. Create a Crop ImageOperation in JDeli (here is how to setup JDeli)

   ImageProcessingOperations imageOps = new ImageProcessingOperations();
   
   imageOps.crop(new Rectangle(0, 0, 100, 100)); //you can add other Operations as well

2. Get a cropped version (x, y, width, height) (0,0 is top left corner)

   JDeli.convert(new File("C:\\path\\to\\picture.jpeg"), new File("C:\\path\\to\\crop.jpeg"), imageOps);
   
   

And that is all you need to do!!!

Below is an example of the cropped and original image

You can also extract GPS data from an image, here is a simple guide to show you, with multiple different tools.
