You can choice any pdf with centered or right aligment text. The one I'm using is DVJU (hope russian and djvu it is not an issue)

Page 2 has title text and ISBN number center and right aligned. When you parse this page, and request coordinates for title (Бэтман Аполло) and isbn (ISBN 978-5-699-63446 -0) text lines it will return left aligned coodinates.
If user click on screen using those coordinates it will not select text on source image properly because coordinates are incorrect.
Convert settins default, and screen size = android screen size, not important, any small screen will suffice 1080x1920
