Rescale the image such that it maintains its aspect ratio but fits within the IconLabel size Public IconLabel(Image image, int width, int height) ![]() Public IconLabel(ImageIcon icon, int width, int height) In this JLabel-extending class, the real tricks are to override getPreferredSize and the paintComponent methods, where I do the image resizing. The getScaledDimension is taken from that URL, and it does a better job of explaining how it resizes an image and maintains its aspect ratio. A tool tip appears that displays the photograph caption. Click any of the thumbnail images to view the full size photographs. Or, to compile and run the example yourself, consult the example index. That way, you can pre-determine how big of a space you want your image to take without compromising its aspect ratio. Click the Launch button to run IconDemo using Java Web Start ( download JDK 7 or later ). For added bonus (and for satisfying my OCD), I have pieced together some logic that also scales the image to within a certain size, maintaining its aspect ratio (i.e., I used ). You may not need the whole IconLabel class, but it does implement the resize technique mentioned above. In the project I am working on, I have been using a modified JLabel to use a resized icon. In this situation, it looks like you do actually need a resized image. All of the posts I have read elsewhere recommend using the BufferedImage/Graphics.drawImage approach. Now recreate the IconImage with the new buffered image: (The code above may be incorrect - check the docs) G.drawImage(img, 0, 0, WIDTH, HEIGHT, null) Then blit the icon image to the buffered image, and resize it as you do so: Now create a buffered image the same size as the image:īufferedImage bi = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_ARGB) Then use getImage() to grab the image from the ImageIcon: Make sure the reference you create is an ImageIcon reference. ImageIcon icon = new ImageIcon("whatever.jpg") You load your image straight into the ImageIcon using the constructor that takes a file name as an argument like: Output: MCQ Practice competitive and technical Multiple Choice Questions and Answers (MCQs) with simple and logical explanations to prepare for tests and interviews.Daniel Searson wrote:Ok, here's one way of doing it.

The Toolkit class is the abstract super class of each implementation in Abstract Window Toolkit (AWT). The font-awesome icon can be placed by using the fa prefix before the icon’s name. To add any icons on the web pages, it needs the font-awesome link inside the head section. The tag and tag are used widely to add icons on the webpages.The Toolkit class is used to get an instance of the Image class in AWT and Swing. It is as simple as applying Font Awesome icon on any button. It changes the icon that is displayed on the left side of the window. The method setIconImage() of the JFrame class is used to change the icon of JFrame or JWindow. In this tutorial, we are going to see how to change java icon in jframe in Java Swing. ![]()
