    <p>Using the <code>java.awt.image</code> (<a href="http://docs.oracle.com/javase/6/docs/api/java/awt/image/package-summary.html">javadoc</a>) and <code>javax.imageio</code> (<a href="http://docs.oracle.com/javase/6/docs/api/javax/imageio/package-summary.html">javadoc</a>) APIs, you can easily loop through the image's pixels and perform the pixelation yourself.</p> <p>Example code follows. You will need at least these imports: <code>javax.imageio.ImageIO</code>, <code>java.awt.image.BufferedImage</code>, <code>java.awt.image.Raster</code>, <code>java.awt.image.WritableRaster</code>, and <code>java.io.File</code>.</p> <p>Example:</p> <pre><code>// How big should the pixelations be? final int PIX_SIZE = 10; // Read the file as an Image img = ImageIO.read(new File("image.jpg")); // Get the raster data (array of pixels) Raster src = img.getData(); // Create an identically-sized output raster WritableRaster dest = src.createCompatibleWritableRaster(); // Loop through every PIX_SIZE pixels, in both x and y directions for(int y = 0; y &lt; src.getHeight(); y += PIX_SIZE) { for(int x = 0; x &lt; src.getWidth(); x += PIX_SIZE) { // Copy the pixel double[] pixel = new double[3]; pixel = src.getPixel(x, y, pixel); // "Paste" the pixel onto the surrounding PIX_SIZE by PIX_SIZE neighbors // Also make sure that our loop never goes outside the bounds of the image for(int yd = y; (yd &lt; y + PIX_SIZE) &amp;&amp; (yd &lt; dest.getHeight()); yd++) { for(int xd = x; (xd &lt; x + PIX_SIZE) &amp;&amp; (xd &lt; dest.getWidth()); xd++) { dest.setPixel(xd, yd, pixel); } } } } // Save the raster back to the Image img.setData(dest); // Write the new file ImageIO.write(img, "jpg", new File("image-pixelated.jpg")); </code></pre> <hr> <p>Edit: I thought I should mention -- the <code>double[] pixel</code> is, as far as I can tell, just the RGB color values. For example, when I dumped a single pixel, it looked like <code>{204.0, 197.0, 189.0}</code>, a light tan color.</p>

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).
