    <p>I need to create many different large tiff files in java for save it as byte array in dataBase. I only managed to copy old file, change it and create new one - but it take too much time to crete the file(TIFFWriter.createTIFFFromImages). what can I do?</p> <pre><code>public byte[] CreateTiff() throws IOException { try{ File orginialFile = new File("../Dist/dist/attachment/orginialTifFile.TIF"); if(orginialFile!=null){ TIFFReader reader = new TIFFReader(orginialFile); int length = reader.countPages(); BufferedImage[] images = new BufferedImage[length]; for (int i = 0; i &lt; length; i++) { images[i] = (BufferedImage)reader.getPage(i); int rgb = 0x000000; // black Random rand = new Random(); int x= rand.nextInt(images[i].getHeight()/2); int y= rand.nextInt(images[i].getWidth()/2); images[i].setRGB(x, y, rgb); } File newAttachmentFile = new File("../Dist/dist/attachment/tempFile.tif"); TIFFWriter.createTIFFFromImages(images, newAttachmentFile); byte[] b= getBytesFromFile(newAttachmentFile); return b; } }catch(Exception e){ System.out.println("failed to add atachment to request"); e.printStackTrace(); return null; } return null; } </code></pre> <p>public static byte[] getBytesFromFile(File file) throws IOException{ InputStream is = new FileInputStream(file); // Get the size of the file long length = file.length();</p> <pre><code> if (length &gt; Integer.MAX_VALUE) { return null; } // Create the byte array to hold the data byte[] bytes = new byte[(int)length]; // Read in the bytes int offset = 0; int numRead = 0; while (offset &lt; bytes.length &amp;&amp; (numRead=is.read(bytes, offset, bytes.length-offset)) &gt;= 0) { offset += numRead; } // Ensure all the bytes have been read in if (offset &lt; bytes.length) { return null; } // Close the input stream and return bytes is.close(); return bytes; } </code></pre> <p>Thanks</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.
