    <p>I'm trying to get the pixel rgb values from a <code>64 x 48</code> bit image. I get some values but nowhere near the <code>3072 (= 64 x 48)</code> values that I'm expecting. I also get:</p> <pre><code>Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Coordinate out of bounds! at sun.awt.image.ByteInterleavedRaster.getDataElements(ByteInterleavedRaster.java:301) at java.awt.image.BufferedImage.getRGB(BufferedImage.java:871) at imagetesting.Main.getPixelData(Main.java:45) at imagetesting.Main.main(Main.java:27) </code></pre> <p>I can't find the out of bounds error...</p> <p>Here's the code:</p> <pre><code>package imagetesting; import java.io.IOException; import javax.imageio.ImageIO; import java.io.File; import java.awt.image.BufferedImage; public class Main { public static final String IMG = "matty.jpg"; public static void main(String[] args) { BufferedImage img; try { img = ImageIO.read(new File(IMG)); int[][] pixelData = new int[img.getHeight() * img.getWidth()][3]; int[] rgb; int counter = 0; for(int i = 0; i &lt; img.getHeight(); i++){ for(int j = 0; j &lt; img.getWidth(); j++){ rgb = getPixelData(img, i, j); for(int k = 0; k &lt; rgb.length; k++){ pixelData[counter][k] = rgb[k]; } counter++; } } } catch (IOException e) { e.printStackTrace(); } } private static int[] getPixelData(BufferedImage img, int x, int y) { int argb = img.getRGB(x, y); int rgb[] = new int[] { (argb &gt;&gt; 16) &amp; 0xff, //red (argb &gt;&gt; 8) &amp; 0xff, //green (argb ) &amp; 0xff //blue }; System.out.println("rgb: " + rgb[0] + " " + rgb[1] + " " + rgb[2]); return rgb; } } </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.
