I would like to produce a PDF that has pages in landscape. While it is possible to set the size of the page to landscape using:
document.setPageSize(PageSize.LETTER.rotate());
this does not achieve what I want because any content that I add is still oriented left->right while I would like it to be bottom->top.
I.E. this is what I am getting:
When what I want is:
I have been able to achieve the desired output by opening the PDF after it has been created and rotating it using iText, but I would like a solution that lets me rotate it immediately with iText after adding content to it.
Excellent question. If I was able to upvote it twice, I would!
You can achieve what you want with a PdfPageEvent
:
public class RotateEvent extends PdfPageEventHelper {
public void onStartPage(PdfWriter writer, Document document) {
writer.addPageDictEntry(PdfName.ROTATE, PdfPage.SEASCAPE);
}
}
You should use this RotateEvent
right after you've defined the writer:
PdfWriter writer = PdfWriter.getInstance(document, os);
writer.setPageEvent(new RotateEvent());
Note that I used SEASCAPE
to get the orientation shown in your image. You can also use LANDSCAPE
if you want the page to be oriented in the other direction.
I need to remember this question once I start writing a third edition of "iText in Action". It's a nice example of when to use the onStartPage()
event.
