Can you rotate an image in Java?
The simplest way to rotate an image in Java is to use the AffineTransformOp class. You can load an image into Java as a BufferedImage and then apply the rotate operation to generate a new BufferedImage.
How do you rotate a JLabel?
A JLabel can explicitly generate a PropertyChangeListener interface. By default, JLabel can display a text in the horizontal position and we can rotate a JLabel text by implementing the rotate() method of Graphics2D class inside the paintComponent().

- Find the transpose of the matrix.
- Swap the element at index 0 with index n-1.
- Return the output.
What is rotation in image processing?
Image rotation is a common image processing routine with applications in matching, alignment, and other image-based algorithms. The input to an image rotation routine is an image, the rotation angle θ, and a point about which rotation is done. An image rotated by 45°.
How do you rotate a matrix?
To rotate counterclockwise about the origin, multiply the vertex matrix by the given matrix. Example: Find the coordinates of the vertices of the image ΔXYZ with X(1,2),Y(3,5) and Z(−3,4) after it is rotated 180° counterclockwise about the origin. Write the ordered pairs as a vertex matrix.
