#NETBEANS JLABEL ICON RESIZE CODE#
And then put the image into the Images folder and write code below. (If you are using NetBeans IDE) Just create a folder in your project but out side of src folder. Click OK and a new image is created, named after the original, together with the new dimensions. Choose the Resize action and a new dialog pops up. How to resize image in netbeansĪdds resize action to image nodes in the explorer views. 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. Create a BufferedImage object for the output image with a desired width and height. In Java, to resize (or scale) an image read from an image file and save the scaled image into another image file, we can follow these steps: Create a BufferedImage object for the input image by calling the method read (File) of the ImageIO class.

Notice the last parameter: it tells to the runtime the algorithm you want to use for resizing. Image newImage = yourImage.getScaledInstance (newWidth, newHeight, Image.SCALE_DEFAULT) Ovbiously, replace newWidth and newHeight with the dimensions of the specified image. In other words, the whole picture always gets displayed regardless of the canvas size, while maintaining the image aspect ratio. When the frame is resized, the image is re-scaled automatically to fit the frame’s new size. Setting a JFrame to fill half the screen One good thing about sharing this code is that you can easily use adapt it to set a JFrame to other sizes.įor example: we draw an image inside a JFrame window. Java resize image to fit JFrameĪs you can see from the code, the method uses the Toolkit class to determine the current screen size, then sets the size of the given JFrame with the setSize method. JLabel is inactive to input events such a mouse focus or keyboard focus. JLabel is only a display of text or image and it cannot get focus. JLabel is used to display a short string or an image icon.

This java example shows how to set image icon for JLabel using setIcon method of Java Swing JLabel class. When the value changes, the label and the components that are next to it jump around a little bit, and it looks bad. I have a JLabel that displays a numerical value the value changes during the program, from 0 to 100 %. Intersting thing is that if we dont know the actual width and height of the image and its not perfectly fitting in label then we can use the two methods of icon getIconWidth () and getIconHeight () as arguments in setBounds () method. Then we can set the location and size of the Image/icon using the method setBounds (). Once you've scaled the image to the size you want, the JLabel will take the size of the ImageIcon. You do not have to set the preferred size of the JLabel. Create an ImageIcon from the resized BufferedImage. Resize the BufferedImage to another BufferedImage that's the size of the JLabel.
