copied!<p>I agree this code works, to size an ImageIcon from a file for display while keeping the aspect ratio I have used the below.</p> <pre><code>/* * source File of image, maxHeight pixels of height available, maxWidth pixels of width available * @return an ImageIcon for adding to a label */ public ImageIcon rescaleImage(File source,int maxHeight, int maxWidth) { int newHeight = 0, newWidth = 0; // Variables for the new height and width int priorHeight = 0, priorWidth = 0; BufferedImage image = null; ImageIcon sizeImage; try { image = ImageIO.read(source); // get the image } catch (Exception e) { e.printStackTrace(); System.out.println("Picture upload attempted & failed"); } sizeImage = new ImageIcon(image); if(sizeImage != null) { priorHeight = sizeImage.getIconHeight(); priorWidth = sizeImage.getIconWidth(); } // Calculate the correct new height and width if((float)priorHeight/(float)priorWidth > (float)maxHeight/(float)maxWidth) { newHeight = maxHeight; newWidth = (int)(((float)priorWidth/(float)priorHeight)*(float)newHeight); } else { newWidth = maxWidth; newHeight = (int)(((float)priorHeight/(float)priorWidth)*(float)newWidth); } // Resize the image // 1. Create a new Buffered Image and Graphic2D object BufferedImage resizedImg = new BufferedImage(newWidth, newHeight, BufferedImage.TYPE_INT_RGB); Graphics2D g2 = resizedImg.createGraphics(); // 2.
