Making Links in PDF
Hello,
I get an "Exception in thread "AWT-EventQueue-0"
java.lang.IllegalArgumentException: Cannot reference this object. It doesn't
have an object number"
Is there somehting wrong with using "addLink"?
<pre>
PDFDocumentGraphics2D pdf2D;
AffineTransform Tx = new AffineTransform( 1, 0, 0, 1, 0, 0);
Rectangle2D rect = new Rectangle2D.Double ();
rect.setRect (20., 20., 100., 50.);
// 0 --> other files
// 1 --> another pos in same file
// 2 --> URL
pdf2D.addLink(rect, Tx, "[/XYZ 0 0 null]", 1);
</pre>
Thank you
Tim

Oh, that line is just a left-over from some experiments. It just makes a
copy of the other AffineTransform. You could use it directly.

Thanks a lot, now it works as I wanted it to.
But one more thing, I don't get, is why do you use the AffineTansform a 2nd
time, before the addLink in your example:
AffineTransform pdfInitialTransform = new AffineTransform(
1, 0, 0, -1, 0, pageSize.height);
g2d.translate(20, 20);
Rectangle rect = new Rectangle(20, 20, 40, 50);
g2d.setColor(Color.BLUE);
g2d.fill(rect);
>>> AffineTransform tx = new
>>> AffineTransform(pdfInitialTransform);
Rectangle2D targetRect = rect;
g2d.addLink(targetRect, tx, "0 0 595 842", PDFLink.INTERNAL);
Thanks again

You'll have to dig deeper and extend the code. "FitR" is currently
hard-coded. I'm sure that can be improved.
But "/Page /Next" won't work. I haven't found that possibility in the
PDF specification. Take a look at the Table 8.2 in the PDF specification
1.4 on page 475. That shows you what is possible.

Now it works just fine.
But I guess I have to modify the PDFGraphics2D.java, because for internal
links, it'll always start the destination like this:
pdfdest = "/FitR " + dest;
This is probably the reason why "[/XYZ 0 0 null]" won't work either...
public void addLink(Rectangle2D bounds, AffineTransform trans, String
dest, int linkType) {
if (!pdfDoc.getProfile().isAnnotationAllowed()) {
return;
}
preparePainting();
AffineTransform at = getTransform();
Shape b = at.createTransformedShape(bounds);
b = trans.createTransformedShape(b);
if (b != null) {
Rectangle rect = b.getBounds();
if (linkType != PDFLink.EXTERNAL) {
String pdfdest = "/FitR " + dest;
resourceContext.addAnnotation(
pdfDoc.getFactory().makeLink(rect, getPageReference(),
pdfdest));
} else {
resourceContext.addAnnotation(
pdfDoc.getFactory().makeLink(rect, dest, linkType, 0));
}
}
}

I've tried to change the destination from
String pdfdest = "/FitR " + dest;
to
String pdfdest = "/Page /Next";
but this won't do it. I guess I have to dig deeper for it or do you have any
suggestions to link the prev. and next page?
Thanks

Yes, you'll need that fix I mentioned. You'll have to use the latest FOP
Trunk directly from the Subversion repository.

Hey,
first of all I gotta say: a big thanks to you and your support, I got some
things fixed, I thought I'd never find the answer for :confused:
But unfortunately there's still the "Cannot reference this object. It
doesn't have an object number" error, when calling:
g2d.addLink(targetRect, tx, "0 0 595 842", PDFLink.INTERNAL);
What fop are you using?
Is that "SVG #svgView(viewBox())" bug-fix necessary, you mentioned earlier?
Thanks again Tim

Yeah, it should be something like :
pdf2D.addLink(rect, Tx, "0 0 595 842", 1);
The four values make up the window for /FitR (which is implicit).
Here's a complete example I wrote to test this:
File outputFile = new File("D:/out.pdf");
OutputStream out = new java.io.FileOutputStream(outputFile);
out = new java.io.BufferedOutputStream(out);
try {
PDFDocumentGraphics2D g2d = new PDFDocumentGraphics2D();
g2d.setDeviceDPI(PDFDocumentGraphics2D.NORMAL_PDF_RESOLUTION);
g2d.setGraphicContext(new GraphicContext());
Dimension pageSize = new Dimension(595, 842); //A4
g2d.setupDocument(out, pageSize.width, pageSize.height);
AffineTransform pdfInitialTransform = new AffineTransform(
1, 0, 0, -1, 0, pageSize.height);
g2d.translate(20, 20);
Rectangle rect = new Rectangle(20, 20, 40, 50);
g2d.setColor(Color.BLUE);
g2d.fill(rect);
AffineTransform tx = new AffineTransform(pdfInitialTransform);
Rectangle2D targetRect = rect;
//Works:
//g2d.addLink(targetRect, tx, "http://www.apache.org", PDFLink.EXTERNAL);
//Doesn't work
//g2d.addLink(targetRect, tx, "[/XYZ 0 0 null]", PDFLink.INTERNAL);
//Works:
g2d.addLink(targetRect, tx, "0 0 595 842", PDFLink.INTERNAL);
g2d.finish();
} finally {
IOUtils.closeQuietly(out);

Re: Making Links in PDF
Posted by useratnab <Ti...@gmx.net>.
Hey Jeremias,
thanks for looking on it.
My intension is to add some internal links from one page to another like it
is done with pdfmarks in ps-files. I'm drawing some "shapes" on a JPanel and
these are painted onto the PDFDocumentGraphics2D. Now there should be a
frame around the shape, where a user can click on it to get redirected onto
another page in the pdf where there is a detailed view of that shape.
Somehow
pdf2D.addLink(rect, Tx, "/FitR", 1);
won't work either.
Thanks Tim

Re: Making Links in PDF

Finally got to look into that. Two things:
1. There was a bug in PDFFactory that caused the bug you mention. I've
just fixed that: http://svn.apache.org/viewvc?rev=744690&view=rev
But that only really fixes part of a problem with SVG #svgView(viewBox())
functionality (as mentioned in the commit message). For reference, the
SVG test case to reproduce the problem can be found here:
http://svn.apache.org/repos/asf/xmlgraphics/batik/trunk/samples/tests/spec/linking/linkingViewBox.svg
2. But you seem to want to use PDFDocumentGraphics2D outside an SVG
context. Looking at the code I don't think that was foreseen. The code
covers only the functionality required by above-mentioned #svgView stuff,
either external links or the viewBox() method (FitR in PDF). Things like
/XYZ cannot be done using PDFGraphics2D.addLink at the moment. For that,
the code would have to be refactored.
If you pass "0 0 10 10" (or other 4 integers representing arguments to
the /FitR function) as "dest" parameter into addLink(), it should work.
But specifying the function itself will lead to errors in Acrobat Reader.
Patches to improve that (and above SVG problem) are welcome.
