Changes in Page View

[Demonica]

I used to be able to see a lovely bar on the left hand of all the books I opened showing me how many pages each book had, giving me options to print, etc. Where did it all go? It all vanished with the new install. How do I get it back please?

I got back the side bar but not the page count. How do I get the page count back please?

How does that make the page count show, please?

I've attached an image of my preference settings and the viewer with those settings.

Note the 3 circled items in the footer. The first is clock, the second is position in book (current position/total) and third is position in chapter (current position/total). These are set in the preferences for the footer as seen in the image for the Headers and footers preferences page.

In flowable ebooks there's no page count as such, like a paper book. That's because the user has control over variables like page (window) size, font size, margins and such. Position in book is analogous to page counts in a flowable ebook.

I don't know about any 'wars'; I just wanted to know how many pages the book has as published under a given ISBN. I've found that in older versions of Calibre it shows those in a place where I liked to see them, so I will go back to that ☺️

The problem is that page counts for ebooks without embedded page information is going to depend on how pages are counted. Do we count one page per screen? One alternate method used by Adobe gives approximately one page per 1024 compressed characters? The first has issues with screen size, font size, margins, etc. affect the number of pages while the second will give you the same results on any software/device when using the identical book file but a bit hard to explain why page numbers show up any where on a screen.

And yes, there have been many electrons recycled in arguments about page numbers in these and other forums. After all, even with dead tree books, different editions can have different page counts even if you are not considering hardcover, trade paperback and regular paperback versions. To slightly misquote Misty Lackey, there is no one true page number.

Just as an FYI, here's the calculating synthetic page numbers from the Adobe EPUB Best Practices guide:

1. When page map is not available in the document, Adobe Digital Editions will synthesize a page-map based on the document content. The approach used is the following:
2. Determine a compressed byte length of each resource which is referenced in the spine, subtracting any known encryption overhead (IV size).
3. Assume that there is a page for each 1024 bytes in each resource, rounding up to the nearest whole number of pages for each resource.
4. To map page breaks into a resource, use the number of pages for the resource as determined in step 2, count the number of Unicode characters in the resource; distribute synthetic page breaks in the resource evenly between the characters by dividing the number of characters by the number of pages; if the number of characters don't divide evenly among the pages, round the number of characters per page up and let the last page contain less characters than the rest.
