copied!<p><em>I have not seriously worked with such an ancient iText version and, therefore, can only point to more current code. A quick look at the svn annotate results seems to indicate, though, that most of the central functionality has been present in iText for a long time. Thus, this code should at least show you how to get started.</em></p> <p>PDF knows the concept of a tiling pattern, confer section 8.7.3 <em>Tiling Patterns</em> of <a href="http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf" rel="nofollow">ISO 32000-1</a>, which should be what you need to create the proper background. iText supports such tiling patterns as demonstrated in the example <a href="http://itextpdf.com/examples/iia.php?id=179" rel="nofollow">TilingPatternColor.java</a> using a helper method from <a href="http://itextpdf.com/examples/iia.php?id=177" rel="nofollow">DeviceColor.java</a>. An excerpt:</p> <pre><code>PdfContentByte canvas = writer.getDirectContent(); PdfPatternPainter square = canvas.createPattern(15, 15); square.setColorFill(new BaseColor(0xFF, 0xFF, 0x00)); square.setColorStroke(new BaseColor(0xFF, 0x00, 0x00)); square.rectangle(5, 5, 5, 5); square.fillStroke(); </code></pre> <p>Having defined a <code>PdfPatternPainter</code> like this, you can generate a color instance from it as <code>new PatternColor(square)</code> and use this color.</p> <p>The samples uses it like this:</p> <pre><code>canvas.saveState(); canvas.setColorFill(new PatternColor(square)); canvas.rectangle(36, 696, 126, 126); canvas.fillStroke(); canvas.restoreState(); </code></pre> <p>You of course have to design your <code>PdfPatternPainter</code> differently. As it essentially is a <code>PdfTemplate</code>, though, you have all the means required to create any tiling pattern you want.</p>
