Hi all.
I'm trying to get the current Y coordinate while I"m inserting text
and images into a ColumnText. I've tried a bunch of things, none of
which seemed to work. Here's a summary:
(1) PdfWriter.getVerticalPosition() and
PdfWriter.getVerticalPosition(true)
both always return the same value: 806.0
(2) PdfWriter.setPageEvent()
I created an inner class that extends PdfPageEventHelper and overrides
onParagraph() and onParagraphEnd(). Neither routine was ever
called. I also
wrote a class that implements PdfPageEvent, just on the off chance that
I misspelled one of the routine names or the method signatures were
wrong.
In this case, onEndPage(), onStartPage(), and onCloseDocument() were
called,
so I know the class is being registered properly, but I still didn't
get any
callbacks to onParagraph[End](). Is there something I need to do to
enable
paragraph callbacks? The code looks something like this:
public class Handler extends PdfPageEvent {
...
public void onParagraph (PdfWriter writer, Document
document, float position) {
System.out.println ("onParagraph");
}
...
}
...
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance (document,
outputStream);
document.open();
writer.setPageEvent (new Handler());
...
Any suggestions?
Thanks!
Greg
