You might occasionally see that the page number for the extracted annotation might differ from the actual page number that is indicated in the document.
A good example for this would be a PDF file that has a few blank pages at the beginning, while the actual book starts a few pages down the line. Some PDF files contain specific metadata for this - it is called Page Label, which normally has page numbers, section numbers, etc. i.e. V, VII, VIII or 1A, 1B, 1C, 2B, etc.... Unfortunately it is not supported in all PDF documents.
In order to avoid unpredictable behaviour and bugs, Sumnotes simply assigns a sequential page number to each annotation. For example, if there is one blank page at the beginning of the document, and the annotation is on the following page, the page number assigned to the annotation would be 2.
We have looked into several ways of making this straightforward and not too confusing, so that there is a clear understanding on what "Page Labels" are and what is the simple page count that starts from 1 no matter what. As a simple workaround, Sumnotes will allow you to offset any number of pages from the top, so that you can line up the sequential page numbers and the actual page numbers of the document.
