page property
The page on which a block was detected. Page is returned by
asynchronous operations. Page values greater than 1 are only returned for
multipage documents that are in PDF format. A scanned image (JPEG/PNG), even
if it contains multiple document pages, is considered to be a single-page
document. The value of Page is always 1. Synchronous operations
don't return Page because every input document is considered to
be a single-page document.
Implementation
