Kindle iOS Text Cutoff

Hey folks, been a few years. Seems like MobileRead hasn't changed a smidge

...I can't seem to avoid posting about K4iOS. For those of you wishing for more diversity in my content, please find forgiveness within you.

I have a pretty recent version of Kindle for iOS loaded on an iPad, and I side-loaded (via AZK) a book I'm working on. Looks decent overall, but occasionally (and particularly near the start of chapters) the layout engine will cut a line of text in half (horizontally) at the bottom of the page, so I only get a peek at the ascenders. The start of the next page has the bottom half of the mutilated line of text.

Once this happens, it tends to repeat throughout a chapter. Some chapters are not an issue, and if I use hyperlink navigation to jump around and change the reflow start point, I can often fake it out.

...Question is, before I spend 100 hours messing with my file, is this a known K4iOS bug, perhaps with a known solution?

I do not use the AZK sideloading feature and I have not seen any reports from others of the sort of problem you are experiencing. From your description it sounds like something in your content is triggering a bug in the renderer.

In case you are not already aware, AZK format makes use of the KCR renderer in the Kindle for iOS app. That renderer in turn uses the native HTML renderer provided by iOS. So any problems you experience may be related to the combination of Kindle app version and iOS version on your device.

You didn't mention iTunes. It's my understanding that we can no longer sideload a book to an iPad or iPhone, but must do it through iTunes. Wouldn't that also be true of K4Mac?

I hasten to add that I have never used any Apple device save an ancient iPod and an almost-as-ancient iPhone 4, which is now on its second battery and which I use every day.

AZK files are sideloaded to the Kindle for iOS app using iTunes.

Kindle for Mac has its own way of doing things and does not rely on iTunes. Recent Kindle for Mac versions did away with the KF8 (azw3) renderer and instead converts books in KF8 format to AZK/KCR format for rendering.

I'm sorry--I've never seen this. Are you doing anything unusual with this file? Layoutwise? Setting widows, orphans, line-heights, or...?

Is there some other method of previewing books on K4iOS that you use? Or, do you not preview on K4iOS?

In talking to a buddy of mine, he has seen this effect with many books by a particular publisher, which is an interesting statement that I will have to pursue.

Yes, it does seem like something in the content, I figured as much

I had some idea that AZK became KCR, but not that the renderer uses iOS's WebKit. I mean, it would make sense, but I guess they also figured out how to turn off the webkit debugger you normally have

(As a note, you guys also mentioned K4Mac--my issue is with K4iOS in particular.)

I'll dig into the file and post back some of what I find, maybe it will be revealing. The next step after that will be to start hacking out styles and see what gives first...

I believe that how a book renders as AZK/KCR is no longer relevant unless the book will not be supporting Enhanced Typesetting, such as a fixed layout children's book.

Most books will support ET and Amazon will deliver them in KFX format to the K4iOS app when actually published. (Perhaps a few customers still have iOS devices that only run a very outdated version of the app, but I doubt that there are very many of those left.)

I do occasionally want to see how a book will look under K4iOS, not because I am publishing, but because I want to understand how the Kindle platform works. I use my KFX Output calibre plugin in CLI mode to convert from EPUB to KFX and sideload that via iTunes. (Using the CLI mode of the plugin avoids manipulation of the book by calibre's conversion pipeline.)

Sez you {grumble grumble}. I wish someone would tell that to my clients. If I deal with one "I sent my mobi to my iPad and it looks HOOORRRIBLE!," complaint per week, I deal with 3. It's just...grrrrrrrrr.

Does anyone here think it's possible that the old xpgt doodad plays a part in this? The original iBooks app was built on ADE, right? I realize that sounds a bit backwards, but...I wonder. I mean, the cheapie shops, like the Big publishers used for backlists, used to just take the scanned crap, slam it into ePUB format, slam in an xpgt page template and then build the mobis by dropping the ePUB's OPF onto KG, right? I realize that we're talking K4iOS, not iBooks, but...I mean, what I've seen in the old big-shop backlist conversions is pretty criminal.

I realize that's an unformed idea, but I was trying to think what might cause that. I've NEVER seen this and that's bloody odd.

Hmmmm..well, all my customers seem to have the old one.

Hunh, interesting. I don't think I knew that. Thanks!
