    <p>Here is some code I found a long time ago:</p> <pre><code>import java.awt.*; import java.awt.geom.*; import java.awt.image.*; import java.io.*; import java.net.*; import javax.imageio.*; import javax.swing.*; public class RotateImage { public static void main(String[] args) throws IOException { URL url = new URL("http://www.oracle.com/us/assets/im04t0-java-logo-1862786.jpg"); BufferedImage original = ImageIO.read(url); GraphicsConfiguration gc = getDefaultConfiguration(); BufferedImage rotated1 = tilt(original, -Math.PI/2, gc); BufferedImage rotated2 = tilt(original, +Math.PI/4, gc); BufferedImage rotated3 = tilt(original, Math.PI, gc); display(original, rotated1, rotated2, rotated3); } public static BufferedImage tilt(BufferedImage image, double angle, GraphicsConfiguration gc) { double sin = Math.abs(Math.sin(angle)), cos = Math.abs(Math.cos(angle)); int w = image.getWidth(), h = image.getHeight(); int neww = (int)Math.floor(w*cos+h*sin), newh = (int)Math.floor(h*cos+w*sin); int transparency = image.getColorModel().getTransparency(); BufferedImage result = gc.createCompatibleImage(neww, newh, transparency); Graphics2D g = result.createGraphics(); g.translate((neww-w)/2, (newh-h)/2); g.rotate(angle, w/2, h/2); g.drawRenderedImage(image, null); return result; } public static GraphicsConfiguration getDefaultConfiguration() { GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment(); GraphicsDevice gd = ge.getDefaultScreenDevice(); return gd.getDefaultConfiguration(); } public static void display(BufferedImage im1, BufferedImage im2, BufferedImage im3, BufferedImage im4) { JPanel cp = new JPanel(new GridLayout(2,2)); addImage(cp, im1, "original"); addImage(cp, im2, "rotate -PI/2"); addImage(cp, im3, "rotate +PI/4"); addImage(cp, im4, "rotate PI"); JFrame f = new JFrame("RotateImage"); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setContentPane(cp); f.pack(); f.setLocationRelativeTo(null); f.setVisible(true); } static void addImage(Container cp, BufferedImage im, String title) { JLabel lbl = new JLabel(new ImageIcon(im)); lbl.setBorder(BorderFactory.createTitledBorder(title)); cp.add(lbl); } } </code></pre> <p>Edit:</p> <pre><code>// BufferedImage result = gc.createCompatibleImage(neww, newh, transparency); BufferedImage result = gc.createCompatibleImage(neww, newh, Transparency.TRANSLUCENT); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
