You cannot copy patch Custom font sizes from one firmware to the next, it has to be newly calculated every time.

In GeoffR's absence geek1011 is the only one who can confirm (or not) the likely future of this patch.

ETA: It seems Semwize has something you can try but I believe the stuff for LibraH20 users is still missing. I don't know whether Semwize could add that?

Semwize, I think you did it! At least for an H2O2 it produces the KoboRoot file. I haven't yet fully tried it on the H2O2 but I expect it will work great. Thank you.

Hmmm... if you use the font size slider to increase the font size, it should be sticky so going forward, both epub and kepub would still be the same.

The thing is, I don't want to up the slider. I want to make the scale as close to what ePub uses by default as close as possible. I need to know if I have to increase or decrease the number to try to do that.

It takes minutes at most to change this out on your own Jon. There are 15 variations one of which you already eliminated. It’s been hours since you asked the question. Testing out different scales is harmless. You’d know your answer by now if you just try using those variables yourself.

Yes, and I'll update it after I take a break for a week or two.

Hopefully no new firmware in that break time.

Be an experimentalist, Jon. There are 15 values and you have already eliminated 2 (8 and 14). Try the other 14 which should take about 3 minutes each since you can be generating the next patch file as one is installing.

Please report the results here.

To fix the two patches for adjust the font scale so ePub and kepub are the same heres what to do...

1. Set ePub uniform font scale: to yes
2. Set Set font scale factor: to yes
3. In Set font scale factor: set the ePub replace value to 4 and set the KePub replace value to 14.

Code:

Set font scale factor:
  - Enabled: yes
  - Description: |
      This patch sets the font scale factor for ePub and KePub readers.
      See also `ePub uniform font scale` and `Custom font sizes` patches.
  # Font scale factor is calculated as (font size slider) / (X+32)
  # Original value X=14, so original scale factor is (font size slider) / 46.
  # Allowed replacement values for X: 0-15 (smaller X --> larger scale factor)
  - ReplaceInt: {Offset: 0x52767A, Find: 14, Replace: 4} # ePub
  - ReplaceInt: {Offset: 0xAE037C, Find: 14, Replace: 4} # KePub

Values of 4 and 4 keeps the scale matching what's used with ePub. So that will improve kepub as well and it will allow kepub to have some larger font sizes should that be needed.

If you also use the patch KePub stylesheet additions:, do not use Example 4: Make KePub font sizes match ePub font sizes: ePubs render with 1.5 times the font size of KePubs by default. With this enabled they match as it will throw off the font sizes.

@Geek1011, can you please change the scale values from 8 to 4? Thanks.

A value of 4 keeps the scale matching what's used with ePub. So that will improve kepub as well and it will allow kepub to have some larger font sizes should that be needed.

@Geek1011, can you please change the scale values from 8 to 4? Thanks.

Thanks for testing! Can you send me the kepub and epub books used for testing so I can ensure they are proper? If so, I'll update the values. The thing is, some epubs modify the base font size, which messes up the whole font scaling thing.

P.S. I was just thinking about the long feedback loop when testing libnickel patches, so I've decided to look at options for speeding the process up. I might try (after I take a break) something with live-patching the binary using ptrace (something like https://github.com/darx0r/poke), but I haven't ever tried this sort of thing before, so I don't know how feasible it'll be. It partly depends on how much funny stuff Qt does and how new the kernel is. Note that this won't work for CSS patches, although I've been doing some experiments with that recently. No guarantees this will work, though. This paper looks interesting: https://www.kernel.org/doc/ols/2008/...es-245-254.pdf.

Hi
I'm new and sorry if this is not the right place but I want to ask
is there a patch which Replaces keys on the Extended Latin keypad with Bulgarian alternatives for firmware 4.18.13737.

Svens · 10-03-2019, 09:00 AM

Can the "Cyrillic Keyboard (GloHD / ClaraHD / AuraOne / H2O2)" patch from 4.15.12920 be applied without modification to 4.18.13737?
Thanks!
