[Conversion Plugin] KFX Input

[Yayasuminu]

"If the contents of the book with edits included is desired, disable the KPF Extract file type plugin to import KPF files unchanged for conversion by this plugin."

So... I am dealing with a problem to convert KPF files to mobi, because calibre DOESN'T recognize it as a KPF file, but as a DOCX instead. So how can I disable this KPF extract mentioned? I really need to fix this problem.

To disable the KPF Extract plugin:

• Click on the "Preferences" icon
• Click on the "Plugins" icon (in the Advanced section)
• Expand the "File type plugins" section
• Select "KPF Extract (1.0.0) by Kovid Goyal" so that it is highlighted
• Click the "Enable/disable plugin" button below (The message "This plugin has been disabled" will appear below the plugin description.)
• Click the "Apply" button

Repeat this procedure if you want to re-enable the plugin in the future.

Import cannot currently be performed on KFX books downloaded using Kindle for PC/Mac version 1.25 or greater due to new DRM.

Is this still true for the latest versions of KFX Input and Apprentice Alf's tools? The deDRM blog says that you can use Kindle For PC 1.26 without a problem.

The information in the first post of this thread is out of date. I will fix it.

Thanks.

Version 1.34.0 - 12 Sep 2020

By default books that use a fixed layout, such as comics and print replica books, will no longer convert within calibre. The option to ignore errors can be used to force conversion, but will yield poor results. Use the KFX Input CLI for those books instead.

Add option to plugin CLI to extract PDF resources from KFX print replica books and to create a PDF file from KFX comic books.

Fix scaling of pixels and handle rotated pages when print replica to fixed-layout EPUB. (Fixes "Unexpected Ion symbols used: $549" and "Unexpected style definition: -webkit-transform")

Support additional KFX features. (Fixes "Unexpected Ion symbols used: $765, $766")

Internal code restructuring.

Dear jhowell,

Could you be so kind to explain to a non-technical user how precisely to operate the command line interface [CLI]? I have located the "calibre-debug" unix executable file but have not succeeded at executing the code you provide on the first page. To be honest, I am not even sure if I am supposed to be inputting anything into that specific file. I have attempted to input the code with a dozen variations in an attempt to solve this myself, but would really appreciate a more specific explanation. Thank you for your time.

Documentation for calibre-debug can be found here.

I do not use Linux so I cannot provide exact instructions for your system. In general the steps needed are as follows:

• Import the book using the calibre GUI. It should import as KFX format. If it shows KFX-ZIP instead then something went wrong with the import process and you will need to correct that before proceeding.
• Export the book format from calibre using the "Save to disk" function. Choose a destination that you will be able to find later. (Using the option to "Save to disk in a single directory" may make the exported file easier to find.)
• Launch a terminal window for entry of commands and change to the directory that contains your exported file.
• Enter the command to invoke the plugin. For example, if your exported file is named Frankenstein - Mary W. Shelley.kfx you can convert to EPUB with the command:
  calibre-debug -r "KFX Input" -- -e "Frankenstein - Mary W. Shelley.kfx"
  Or you can to extract any embedded PDF resources with the command:
  calibre-debug -r "KFX Input" -- -p "Frankenstein - Mary W. Shelley.kfx"
  (Note the a combination of single and double dashes are needed.)

Dear Jhowell,
Thanks so much for this speedy reply. I am afraid that my knowledge is still too amateur to be able to keep up here (I really have no experience using terminal at all). I have succeeded at importing my book into calibre, and exporting it as a .kfx. I also managed to open terminal and change my directory to the folder containing my exported .kfx. However, when I enter the code, terminal says it does not recognize the command "calibre-debug." I even attempted to move the .kfx file into "/Applications/calibre.app/Contents/MacOS", which contains the "calibre-debug" executable, and set this folder as my directory, but terminal still did not recognize the command.

Apologies as i know this is extremely basic stuff for you. But any further assistance would be immensly appreciated. Thank you.

I am not an expert on MacOS, but I believe that it should work if you use the full path for the command:

/Applications/calibre.app/Contents/MacOS/calibre-debug

This worked! Thank you so much for your generosity here.

I have been using an old version of Kindle for PC2 under Windows 10 for ages and have been able to archive Kindle files by dropping into Calibre.

I inadvertently allowed Kindle for PC2 to be updated -- 1.30.0 (59056). The Calibre version I am using is Release: 5.3 [16 Oct, 2020].

Am I stuck forever or is the Calibre plugin updated periodically to catch up with Kindle for PC2 updates? Alternately, can I deinstall this Kindle for PC2 and find an older version somewhere?

Many thanks.

I see there are a couple of threads elsewhere on K4PC updates to 1.30.
