--------------------------------------------------------------
1. If you want to customise the orientation, then you don't want to use
PDFPageable. The purpose of a Pageable interface is to let the source document
determine its own layout. If you want to do something custom, then skip the
Pageable and use a Printable directly.
2. We could add an API to change the centering behaviour. Why isn't centering
working for you? Note that if you're using a custom page layout then you can
set the imageable area to the same size as the PDF page and then the centering
will have no effect.
Take a look at our
[Printing|https://github.com/apache/pdfbox/blob/trunk/examples/src/main/java/org/apache/pdfbox/examples/printing/Printing.java]
examples, specifically printWithPaper(), which supports custom page layouts
via Book.
