Bookmarks with xhtmlrenderer (iText)
I'm using xhtmlrenderer (Also known as Fly开发者_如何学Cing Saucer) with iText to convert HTML to PDF. How would I create bookmarks with this? Does someone with have a small example?
Thanks in advance.
It seems bookmarks were added in R6, but the user guide only gives them a passing reference. with a TODO to the author to add an example later.
Searching the forums, I found this example:
<html>
<head>
<bookmarks>
<bookmark name="A bookmark" href="#bm" />
<bookmark name="A bookmark 2" href="#bm2" />
<bookmark name="A bookmark 3" href="#bm3" />
<bookmark name="A bookmark 4" href="#bm4" />
<bookmark name="A bookmark invalid" href="#bm99" />
</bookmarks>
</head>
<body>
<div style="line-height: 100%; font-size: 12pt; page-break-before: always;">
<a name="bm">some text</a>
</div>
<div style="line-height: 100%; font-size: 12pt; page-break-before: always;">
<a name="bm2">some text</a>
</div>
<div style="line-height: 100%; font-size: 12pt; page-break-before: always;">
<a name="bm3">some text</a>
</div>
<div style="line-height: 100%; font-size: 12pt; page-break-before: always;">
<p>some text</p> <p>some text</p> <p>some text</p> <p>some text</p> <p>some text</p> <p>some text</p>
<p><a name="bm4">and some more text</a></p>
</div>
</body>
</html>`
So it seems that adding bookmarks is no more than declaring the bookmarks in the <head> and referencing them as anchors in the <body>.
This should work will with your existing XHTML->PDF conversion without requiring any code changes.
Its correct that above approach will work.
Sample example from flyingsaucer-R8-src modified for BookMarks Demonstration
public class PDFRenderToMultiplePages {
public static void main(String[] args) throws Exception {
OutputStream os = null;
try {
final String[] inputs = new String[] { newPageHtml(1, "red"),
newPageHtml(2, "blue"), newPageHtml(3, "green") };
final File outputFile = File.createTempFile("FlyingSacuer", ".pdf");
os = new FileOutputStream(outputFile);
ITextRenderer renderer = new ITextRenderer();
renderer.setDocumentFromString(inputs[0]);
renderer.layout();
renderer.createPDF(os, false);
BlockBox rootBox = renderer.getRootBox();
for (int i = 1; i < inputs.length; i++) {
renderer.setDocumentFromString(inputs[i]);
renderer.layout();
renderer.writeNextDocument();
}
renderer.finishPDF();
System.out.println("Sample file with " + inputs.length
+ " documents rendered as PDF to " + outputFile);
} finally {
if (os != null) {
try {
os.close();
} catch (IOException e) { /* ignore */
}
}
}
}
private static String newPageHtml(int pageNo, String color) {
return "<html><head><bookmarks>"
+ "<bookmark name=\"bookmark"
+ pageNo
+ "\" href=\"#bookMark\"/></bookmarks></head>"
+ "<body><div style=\"color:"
+ color
+ ""
+ ";\"><a name=\"bookMark\">Book Mark Example</a></div></body></html>";
}
}
