Go to menu Image > New Device Image, or right-click in the Image Editor pane and choose New Device Image. You can use Java’s ImageIO or a third-party image library such as JDeli to load and save the image. You can load an image into Java as a BufferedImage and then apply the scaling operation to generate a new BufferedImage. The simplest way to scale an image in Java is to use the AffineTransformOp class.
BufferedImage class, which extends the Image class to allow the application to operate directly with image data (for example, retrieving or setting up the pixel color). Image class is the superclass that represents graphical images as rectangular arrays of pixels. To get the bigger icons back we simply deselect Small Toolbar Icons. We have to go to View | Toolbars and then select Small Toolbar Icons. The toolbar icons in NetBeans can be shown in a smaller size. SetImage(Image image) Sets the image displayed by this icon. SetDescription(String description) Sets the description of the image. PaintIcon(Component c, Graphics g, int x, int y) Paints the icon. Which method is used to display icon on a component? Obtain a Graphics2D object from the output image’s BufferedImage object.Create a BufferedImage object for the output image with a desired width and height.
Create a BufferedImage object for the input image by calling the method read(File) of the ImageIO class.How do you change the size of an image in Java? You can use ImageIcon class to load your image file and then simply call getter method to get the image. The first parameter is a Image class which you can easily get from ImageIcon class. You need to use Java’s graphics 2D to scale the image. Resizing the icon is not straightforward.
