Changing configuration of MARGINS and FONT SIZES - possible?

[Analogus]

Just MOBI-Books or AZW3-files?

[Mr.Samuel]

Mobi only

[Analogus]

Hi

Yes, that should be possible. Found numbers fitting to linespace in the code:
1.4
1.49
1.6

in class: MobiReaderImplResources_de.class (for the german version. Eglish version should be the same)

Shall I change it and put it online?
But be aware. I do have 5.8.7 for VOYAGE.

And besides:
It also should be possible to change FONT SIZES for MOBI the same way.

[Mr.Samuel]

I just found that values yesterday , I will modify that jar file today and check out whether the line spacing is bigger or not.

[Analogus]

I'm very interrested in a feedback from you if, and when yes, how it is working.

[Mr.Samuel]

I have modified the class file with JBE, but nothing changed .
Which bytecode editor did you edit the jar?
Did you open the jar file with the editor or just modified the class file and compressed into the jar?

[Analogus]

Hi

What I did:

1) Extract CLASS-file with ZIP or RAR
2) Edited CLASS-file in JavaBytcodeEditor
3) Put file into JAR with ZIP ord RAR

To edit the class-file maybe another decompiler could be a better joice.

Its absolitely necessary to restart the reader after the changes!

[Mr.Samuel]

I will try it next time.

[Waylander]

OK, I've downloaded the JAR file. I have the right Kindle firmware. What do I do with the JAR file? Do I just drop it in the Kindle root? I'm a bit of a novice here so speak slowly with easy words is possible .

[Analogus]

Hi!

No, that's the wrong place.

1) To be sure - did you jailbreak the reader?
2) Do you have access to the file-system? You need it! I did that part with
a) gaining writing access over SSH with just once login over SSH and then b) opended the (hidden) file-system with 'transmit' on the mac
3) overwrite the file(s) in path:
root of the reader: /opt/amazon/ebook/lib/

I would make a backup of the original file(s) just to be on the save side.

Restart the reader and it should work. But:
- only with AZW3-books
- only with german and english language (language setting in reader options, not books of course...)


Ask if unsure!

[Waylander]

Oooooooh. I need to jailbreak first. That would explain it. I'll need help with the file system/SSH bit, but I should be ok if you talk me through it if that's ok?

[Analogus]

Hi

To guide you completely through would be a bit too long, I presume. Do it step by step.

1) Jailbreak your reader

This will take a while, because you should read that carefully.

Do as explained in the first post. You have to grade down your reader in a first step, because jailbreaking is not possible with the newest firmware.
Then jailbreak it. Then upgrade to the new firmware. Then install necessary software.

But, step by step. First: jailbraik your reader. It's not that complex.

Edit:
SSH is simple if you do it on a MAC. For windows you'll need additionally software you have to install on your PC. A MAC can do it without any need of new software to be installed. But without jailbreaking the reader - no luck.

Edit 2:
If you have a MAC, I can guide you through SSH. I have a PC, but never done SSH on Win. Just to be mentioned...

[Waylander]

I've Jb'ed it, which was straightforward. I've got a Mac so should be ok. Also, is there any way to reduce the space at the bottom of the page as well? If there isn't it doesn't matter.

[knc1]

Probably not.
That is where the bottom bar lives, not part of the book display area.

Hmm...
It has one setting where it is blank, maybe that is the only setting you have noticed.
Tap in bottom left corner.

[Waylander]

Oh well. I'd still really like to get the other margins like the OP's though. I've got a Mac so SSH should be more straightforward than on Windows if I knew how.
