That or share the code to PdfReader.getLinks() so we can find your bugs. ;) I,
being infallible, am clearly not to blame.
The act of keeping references to the 'direct' objects from their references like
this was a pretty fundamental change in the way iText works... I compared it to
changing the speed of light by a tiny amount on the dev list. That's what the
"C *= 1.02" thing alludes to in the check-in comment.
Buggy.pdf has 3 named destinations, all of which use the same indirect object, :
Doc-Start [ 4 0 R ]
page.1 [ 4 0 R ]
section.1 [ 4 0 R ]
It's entirely possible that there's a bug in consolidateNamedDestinations()...
induced by my check-in. Lets have a look... nothing glaring at me. Not much of
a 'consolidation' really, but okay. It stuffs the dest array in to replace any
name or string destination.
Okay, how about the line that's actually throwing:
PdfImportedLink(PdfDictionary annotation) {
parameters.putAll(annotation.hashMap);
try {
destination = (PdfArray)
parameters.remove(PdfName.DEST);
} catch (ClassCastException ex) {
throw new IllegalArgumentException("You have to
consolidate the named
destinations of your reader.");
}
That looks an awful lot like it should work. Clearly, something is... amiss.
Only I'm infallible, so it must be your fault, trying to discredit me out of
jealous at how awesome I am.
Or I could have broken something. :\
Can we get a look at your getLink code?
