[Conversion Output] KFX Output

[Shark69]

Hello:
I have recently started with the pluing and I find it very interesting, but I have a question. I am converting a book from epub to azw3 and kfx. Everything is fine, but in ebooks (Kindle Oasis and Kindle Touch), when there is a call to a footer, the line spacing increases in kfx, but not in azw3. If I open the kfx with Kindle Previewer it looks fine.
Attached images of the Kindle Previewer (OK), azw3 (OK) and kfx (increased line spacing).
Do you know the reason?

KFX:


Kindle Previewer:


azw3:

Hi, I encountered the following error when trying converting vertical Chinese ebooks:

Traceback (most recent call last):
  File "calibre_plugins.kfx_output.kfxlib.original_source_epub", line 262, in prepare_for_previewer
  File "calibre_plugins.kfx_output.kfxlib.original_source_epub", line 540, in prepare_opf
TypeError: JobLog.info() takes 2 positional arguments but 3 were given

It seems like a typo:

--- "KFX Output/kfxlib/original_source_epub.py"
+++ test.py
@@ -540 +540 @@
-                        log.info("Changed EPUB language from '%s' to 'ja' for vertical text conversion", lang.text)
+                        log.info("Changed EPUB language from '%s' to 'ja' for vertical text conversion" % lang.text)

Thank you.

Change the [3] and all other footnote markers to be part of the text. Remove the superscript code. Then convert to KFX. That will make the lines no longer have a larger line height and the tap zone will be larger and easier to see.

I sometimes see that happen depending on the font chosen on the Kindle. I don't have any solution other than trying a different font.

Thanks for finding that! It will be fixed in the next release of the plugin.

Thanks both of you. I've found a better solution. If you add this conversion rule in Calibre, the problem is sorted out:
If the property is greater than 20%, change the value to 20%.
That is because in some books, que <sup> property is defined like that:
sup {
font-size: 0.75em;
line-height: 1.2;
vertical-align: super;
vertical-align: 35%;
}
Highier vertical-asign than 20% produces the problem. We can shorten it a little and problem finished.

Setting a fixed line-height is generally discouraged. The line height ought to be controlled by the user settings in the reading software.

You're right

Fix bug introduced in version 1.63.0 of this plugin that prevented the conversion of vertical Chinese language books.

[jhowell]

Amazon has released Kindle Previewer version 3.67.0. It is compatible with the current release of this plugin.

hullo again! I was just trying to convert an epub the other day and received this error:
calibre, version 6.3.0
ERROR: KFX conversion failed: <p><b>Cannot convert The Hero Of Olympus</b><br><br><b>Conversion error:</b> E24010: Hyperlink not resolved in toc (One possible reason can be that the link points to a tag with style display:none):C:\Users\narla\AppData\Local\Temp\49 9925a3-353f-43a6-8c1d-3c04c9060a97\cTemp\mTemp\mbp_7E6_8_1C_B_D_15_38F_1 A3C_3ECC_1\1\1\.html_split_004#</p>

Anything i can do to resolve this?
Thanks in advance

Thank you for your plugin. It works really well for me.

I have some question though: Now I have a manual column of page number, but when I convert a book, I have to go to KFX Output setting to check the "Create approximate page numbers" and specify it to #pages every single time.

Is there any tweak that I can use to make it the default setting?

Thank you.

You can the change defaults for conversion. Go to Preferences, Output Options, KFX Output and set whatever defaults you want. The new defaults will apply for any books that have not been previously converted.

Hi Everyone! I've been browsing around the past hours trying to find a solution to transfer my kfx files from my laptop to my kindle app on the Ipad, without success. Is there any method to do so?

I read the first post with some instructions for IOS devices, but it is not clear how the Kindle app would open the files once I transfer them to my device.
