What are the common methods for manipulating images in Java?

Common image manipulation methods in Java include:

1. Load images: Use the read method of the ImageIO class to load image files, or use the getImage method of the Toolkit class to load image resources.
2. Create an image: Use the drawImage method of the Graphics class to draw an image to a specified position.
3. Resize image: Use the getScaledInstance method of the Image class to resize the image.
4. Rotate image: Use the AffineTransform class to perform image rotation.
5. Crop image: use the getSubimage method of the BufferedImage class to perform the cropping operation on the image.
6. Image composition: combining multiple images into one image can be done using the drawImage method from the Graphics2D class.
7. Transparent image processing: Transparency processing of images can be achieved using the setRGB method of the BufferedImage class or the setComposite method of the Graphics class.
8. You can achieve filter effects for images, such as black and white or blur, by using the ImageFilter class and FilteredImageSource class.
9. Image format conversion: Using the write method of the ImageIO class can save the image as a file in the specified format.
