The list is not sorted under any criteria. Here is a list of popular libraries used for image processing in java. In this listicle, we will mention some of the popular Java libraries that can be used for tasks that involve the processing of images. Even when many other languages dominate over it in the AI and ML space Java still has solutions that can help it stand firm. This puts a lot of programming minds under an urge to come up with solutions to process the varieties of data that would make the job of millions and millions of developers easier.
Data can be text, images, videos, audios or anything. What adds to this is the variety of data. import an era where data is booming and is omnipresent, technology is put to test and bet against its own capabilities to process the ever-growing data. Now that we have the rotated image, we need to create a new file to store it using File and ImageIO.write() that takes the BufferedImage object, its extension the location of the empty file. Now we call the rotateImage() function and pass the returned BufferedImage object and store the rotated BufferedImage object.
In the main function, we read the file using File and then convert it into a BufferedImage object using ImageIO.read(). Then we return the newImageFromBuffer object. Using this object, we call the rotate() function that takes three arguments the first is the angle to rotate the image as we want to rotate it 90 degrees we pass Math.radians(90), the second and third arguments are the x and y coordinates.įinally, we call graphics2D.drawImage() to draw the rotated image, which takes four arguments, the BufferedImage object, the filter to apply, and the x and y coordinates. We create new rotated image using createGraphics() method that returns a Graphics2D object graphics2D.
Now we call the BufferedImage() constructor and pass the three variables as arguments and it returns a BufferedImage object newImageFromBuffer. In rotateImage(), we get the width, height and the type of the image using getWidth(), getHeight() and getType() methods.
Below we create a function rotateImage() that receives a BufferedImage object as a parameter and returns a rotated BufferedImage object. The first method to rotate an image includes the use of the BufferedImage and the Graphics2d class that comes with the AWT package. Rotate an Image in Java Using BufferedImage and Graphics2D.rotate() This article will introduce how we can rotate an image in Java using two native ways.
