iPad/iBooks and page count

eolake · 08-25-2010, 05:44 PM

I was under the impression that iBooks and other ereader apps, sensibly enough, used "locations" instead of page count, because the latter depends on text size. But it seems that Apple iBooks app actually us page count instead so a page number changes with text size. Anybody know a way around this?

I mean how to say to your buddy: "In Snow Leopard Missing Manual, text substitution is on page 575", without knowing what text size he happens to have set?

iBooks should, apparently, support the pageList convention in the epub standard. It's up to the person designing the epub to implement this properly so that the page numbers displayed correspond to a standard reference.

Ah. Thanks.

ADE has a standard way of calculating page numbers based on the text. It has nothing to do with the text size. So in that regard it is fairly easy to find a page without worrying about the size of the text.

iBooks totally breaks this as it re-paginates every time you change the text size and the page numbers are based on the number of screen pages. So iBooks has rather useless page numbers. You'd have to tell someone at 3 up from the smallest font size (not including the smallest font size), go to page 52.

Sony also uses page counts instead of locations. I myself feel more comfortable with pages, although admittedly I haven't yet had to compare text locations with someone else.

For ePub files, Sony (like every other ADE device) use ADE "pages", which are a count of 1k characters in the compressed file. They have no connection with "display pages" on the device.

I'm sorry, I'm a bit of a newbie... What is ADE, please? (I couldn't find it on Wikipedia.)
Hmmm, is it Adobe Digital Editions? Does Sony really use this?

Yes, ADE is Adobe Digital Editions. It's the software which almost every eBook reader except the Apple iPad uses to display both ePub and PDF files. Don't confuse the ADE firmware (which is in the device's ROM) with the ADE desktop application for the PC/Mac.
