JBPatch

[Waylander]

NiLuJe, ixtab et al. I was told that you can port JBPatch to FW 4.1. Is this actually possible, and how do I do this? Any help would be much appreciated.

Is this for porting to FW 4.1? And where is the hyphen option? If this is in response to another post then I apologise for butting in.

Yes, it's possible. It would resemble very much the way to get it to work on the K3 - that is:

1. Find a way to inject the patching class loader as early as possible.
2. Get rid of the UI components. They are not compatible with K3/K4, so they'd have to be completely rewritten, or simply left out.
3. Write useful patches.

References: How does JBPatch work? and arikfunke's post about getting it to work on the K3 (also follow the links from that post).

How do I get rid of the UI components? I can't seem to open the Bin file, so I don't know how to proceed.

Proceed by getting a copy of the KindleTool described elsewhere at this site (check NuLiJe's snapshot thread for instance).

You have to compile JBPatch from source (and to modify the source code to fit your setting, like arikfunke explained in his post). The source code is linked from the first post.

I just want to use the hyphenation patch. Do I still have to do the full JBPatch? Sorry for being such a noob, but its pretty confusing.

Unfortunately yes. And it gets even worse: Not only do you have to port the JBPatch framework itself to the K4, you'd also have to re-develop the entire hyphenation patch from scratch, which is a major reverse engineering task. That's because the firmwares are completely different. It may be easier to use .azw3 (KF8) files with soft hyphenation (see first post of the thread).

[Waylander]

I know about using soft-hyphens, but they only work with azw3 files, and I really wanted to get hyphens with mobi files because the font sizing is better. Any other pointers? Thans for all your help.

I would be grateful if you could write down "edit values" for the font size change part of your hack (Mobi-drawing-en_GB.jar, HTMLReader-impl-en_GB.jar).

Ah, thank you so much. Got it working.

Also, belated found Java Bytecode editor

Very useful.

Happy Thanksgiving to those in North America, and maybe elsewhere

For PW/PW2:

HTMLReaderImplResources_ln_LN.class
htmlreader.font.size.list : 7.13 ; 7.81 ; 8.49 ; 9.17 ; 10.53 ; 12.56 ; 16.98 ; 29.2 > Your eight values

MobiDrawingResources_ln_LN.class
mobi.font.size.mapping : 7.13 ; 7.81 ; 8.49 ; 9.17 ; 10.53 ; 12.56 ; 16.98 ; 29.2 > Your eight values

One line - one value (or one shot - one kill )


Section "167 dpi" for KT, section "212 dpi" for PW.

Parameter <mobi.font.size.mapping/htmlreader.font.size.list>.cjk - for Asian languages.


By default the sizes of fonts on Kindle are resulted to X/100 inches. Height of one point ~0,00469" or ~0,11913 mm.

Font size hacks working in 5.4.0.
Marging hack not working in 5.40.

[NiLuJe]

@levante: You'll notice that 5.4.0 isn't mentioned *anywhere* in kaznelson's post, which might explain your current plight .
