'Single Page' view alignment

A PDF document has pages with portrait orientation. An Android tablet is turned to landscape display orientation. When selecting the 'Single Page' mode in RDPDFReader application, a PDF page is displayed on the left side of screen, rather than at center of screen. Also, when I do text search, a page containing matching text is displayed not at the screen center.
How to correct this from Java code?
Thanks in advance.

Hi,

Thanks for the reply.
It seems I have now to refactor my application so it will be based on the PDFReader sample application (which is based on the PDFVIew class), rather than on RDPDFReader, because PDFLayout class doesn't provide the vCenterPage() method.
Could you please explain what is a difference between PDFView and PDFLayout classes provided by RadaePDF SDK? An objective of two different classes supporting PDF rendering and providing different API is not clear for me at the moment.

Hi,
now we are publishing a new version of the library.
The new RDPDFReader is now stable.
The new rendering approach is faster while zooming and with less memory consumption.
Now zoom factor won’t be a limit anymore and it’s potentially infinite.
