[Conversion Plugin] KFX Input

[jhowell]

Version 1.7.0 - 13 Aug 2018

Fix incorrect image type sometimes being detected for books that were published containing SVG images.

Prevent conversion failure caused by unexpected content in some KFX books. (Fixes "Unexpected box-align value: justify")

Prevent conversion failure caused by alignment of lists in KFX books. (Fixes "Unexpected box-align found in ol element")

Prevent conversion failure caused by drop caps with zero length, sometimes produced by Kindle Create.

Fix incompatibility with calibre versions before 3.0 introduced in plugin version 1.2.0. (Fixes "AttributeError: 'apsw.Cursor' object has no attribute 'fetchone'" when converting from KPF format.)

Support additional KFX features.

[jhowell]

Version 1.8.0 - 30 Aug 2018

Prevent occasional failures when converting some books from e-ink Kindles that contain problematic JPEG-XR images.

Support additional KFX features produced by Kindle Create version 1.12.

Never mind. I found the link under my nose. Thanks anyway.

Hello,

I've been using DeDRM in Calibre for some years now. Today I upgraded both Kindle for PC (1.24.3) and DeDRM (6.61). I've installed this plugin w/o issue. However, I can't find the download location for the KFX Input Plugin. I've read this thread and searched the plugin library, but I can't find it.

Help please?

[Dogbert]

Is it safe to say that a lot of books / files don't have metadata associated with them when they are sourced directly from the maker of the reader? Most of mine don't, and I just want to make sure that I don't have something setup incorrectly where they aren't being read in. Thanks.

Book in KFX format imported from a Kindle device or app will generally have the following metadata: title, author, language, publisher, publication date, and ASIN. A short description will occasionally also be present. You should see these in your calibre library when you add a book in KFX format.

Other metadata, such as series and ISBN, are not contained within the book. You will need to add those manually or download them using metadata plugins.

[Dogbert]

Super. Thanks. Didn't even think of looking at those items. The files in question do have that metadata, so it looks like everything is working as it's supposed to.

Ok what am I missing here?

I try to package both kfx files into a zip file, then rename it ".kfx-zip"

I drop that in Calibre, but it's reading it as a .zip, and not kfx-zip, so it can't convert it.

If calibre sees it as zip format then most likely you have failed to rename the file correctly. Research renaming files for your operating system.

To find out more information you can create an import log. Restart calibre in debug mode (choose this from the menu after right clicking Preferences), import the file, and exit calibre. A log of the import process will appear. You can should be able to determine from that what file type has been imported from that.

Also make sure that you have included all of the files that make up the book in your kfx-zip file.

It might be easier to follow the instructions in the first post of this thread to have the plugin create the kfx-zip for you automatically.

Thanks for the quick response. I feel like I read the instructions 5x, but went back and read them one more time. Realized I was grabbing the wrong KFX file

Import worked as expected and can now successfully convert.

(a) Detailed help with DRM removal isn't permitted here
(b) That's a conversion log. When you ask for detailed help at Alf's blog or Harper's github repository, remember that DRM removal happens on import, not conversion, so you'll need to post an import log.

[BetterRed]

That log contains references to a post at this forum that specifically addresses KFX related problems. There's one at the top, another about 3/4 down and another one at the end.



Try clicking on one of them, the answer may be in that post

A couple of books fail to convert with this message:

Unknown com.amazon.yjconversion feature: reflow-style-8
Unexpected Ion symbols used: $528</p>

On a quick look, converting with ignore errors seems to have worked, except that the in-book TOC is oddly laid out, with the start of each line hidden in the margin.

You have KFX content that I have never seen before and so is not handled by this plugin. It would be helpful to know the name and/or ASIN of those books so that I can look into it further.

Thanks.

I am able to import the book but I am unable to read it. Here is the error message when I try to read it
