Positioning of high level objects after adding direct content 2006-08-23 - By Wolfgang Werner
Back
Hello all,
we are creating pdf files with iText. Several times we found places,
where we would like to
mix high level objects (like chunk / paragraph) and items placed via
direct content.
Example: We do create a page with a header made from some sentences,
then placing a
scaled version of an already existent pdf file, then adding a footer.
However, the footer - formed by a high level paragraph object - will
be placed directly
under the header, covering the inserted pdf file.
The insertion point or the pdf is resolved by a PdfPageEventHelper
which tracks the
the current y-position:
public void onStartPage( PdfWriter writer, Document document ) {
currentYPosition = document.top();
}
public void onParagraphEnd( PdfWriter writer, Document document,
float paragraphPosition ) {
currentYPosition = paragraphPosition;
}
We now need a way to force the internal iText layout system to skip
some y-Space and continue
below our items.
Is there any way to to this, eg.
document.setYPosition()
Any comments are highly appreciated!
Regards, Wolfgang
