Thanks

Only if you transfer all your books as plain epub rather than kepub. What you've asked for is standard for epubs.

With kepubs all you can do is use a patch to reduce the height of the header, or remove both header and footer by configuring to read in fullscreen mode.

Don't forget to change to false when you done.

Good luck!

Thanks!
Seems quite cumbersome, but it's good to know.

The only ones from the previous firmware that are not currently in the attachment to post #1 are `Disable new home screen` and all of the keyboard patches. The new patches listed under Other patches in post #2 are not included yet either.

Thanks. So are the patches listed in post #2 going to be added or will I have to do the ones I want myself?

You're using a patch on the wrong firmware, the one Oren has in this thread is for 4.4.9298 not 4.4.9344

D'Oh!

Ok. Hands up!

Obviously I can't read. Bit ironic that is is about an ereader then!

You can customise one or more of the following:

• font-family (choose any font on your device, built-in or sideloaded)
• font-size
• line-height

As far as I can tell (trial and error) these are the current unpatched Kobo defaults:

         font-family    font-size   line-height
         -----------    ---------   -----------
    Glo: Georgia        23px        1.4em
    H2O: Georgia        29px        1.4em
  GloHD: Georgia        32px        1.4em
AuraONE: Georgia        42px        1.4em

... so work out your new custom font-size/line-height settings using these as a guideline.

Here is the patch code. It goes in libnickel.so.1.0.0.patch.

Spoiler:

<Patch>
patch_name = `Dictionary text font-family/font-size/line-height - beta`

# Multi-version patch: 4.4.9298 - 4.4.9298+
#
# This patch allows you to to customise the appearance of the text 
# in the dictionary pop-up widget and full-screen dictionary page.
#
# You can change one or more of the following attributes:
#   - font-family
#   - font-size
#   - line-height

#
#   to:
#       * { font-size: 40px; line-height: 1.3em; font-family: Georgia                                           ;}
#       ol   { margin-left: 1em; margin-top: 0px; }

find_base_address = `* { font: %1px %2; line-height: %5em; }`
replace_string = 0000, `* { font: %1px %2; line-height: %5em; }\ndiv.descriptionFont { font-family: %3; }\nol { font-size: %1px; font-weight: bold; margin-left: %4em; margin-top: 0px; }\nol p { font-size: %1px; font-weight:normal; }\n`, `* { font-size: 40px; line-height: 1.4em; font-family: Georgia                                           ;}\n        \nol   { margin-left: 1em; margin-top: 0px; }\nol p { font-size:  1em; font-weight:normal; }\n`
# ##### N.B. Do not change anything above this line #####
#
#
# Stage 2: N.B. You MUST keep old and new strings EXACTLY the same length
#
# Un-comment ONE ONLY of the following replace_string examples 
#   to change dictionary font-family from default Georgia:
#   - to a different built-in font
#   - to one of your sideloaded custom fonts
#
# Notes for changing font-family:
#   1.  Pad the shorter of the old/new strings with spaces to 
#       keep same length for both strings (see examples below)
#
#   2.  If the new font-family name (max. 50 chars) contains any spaces it must be
#       wrapped in "double-quotes" (see examples 2, 3)
#
#   3.  To change from Georgia to the Kobo default sans-serif font, Avenir, 
#       use either one of the following to achieve the same result:
#       - sans-serif
#       - "Avenir Next Medium"

#replace_string = 0036, `Georgia `, `Bookerly`
#
# Un-comment and edit next line to change font-size
#replace_string = 000F, `40px`, `30px`
#
# Un-comment and edit next line to change line spacing
#replace_string = 0022, `1.4`, `1.3`
</Patch>

Although the patch code looks quite long, most of it is Help Notes. The only lines you need to change are in the last 10 lines of the patch.

I've attached 3 screenshots:

1. unpatched KA1 [**]
2. patched KA1: font-family: "Gill Sans", font-size: 38px, line-height: 1.1em
3. patched KA1: font-family: Bookerly, font-size: 45px, line-height: 1.4em

[**] Let me rephrase that. By 'unpatched' I mean before this particular patch was enabled. My other dictionary patch `Dictionary frame size - beta8` (in nickel.patch) is already enabled in all 3 of the screenshots. The 2 dictionary patches are not dependent on each other. Enable either, both or neither as you wish.

Please report back in this thread if you have any problems.

Caveat: If you own several different Kobo models it is unlikely that you will be able to find one set of custom values which will look good on all devices so you may need to run the patch process multiple times with a different libnickel.so.1.0.0.patch file for each.

Thank you so much. It's work with vietnamese font. But you create another patch for change font-family "table of content" in book, titles and authors of books in "my book" section. Thanks again.

Now it's time for you to do this all over again with the new 4.5.9587 patch to go along with the new firmware.

Corrections in red. Be especially careful with the font-family patch - the old value string and the new value string must be exactly the same length.

Thanks it seems working... I was worried because I've made several .tgz (editing the .patch files) and tried them one after the other on the device (that is working well). Can I let it so or must I do a factory reset?
Can I keep the final .tgz or make an other one?

Thanks

Each time you create a .tgz via the patcher it is a complete re-write of only the 1,2,3 or 4 files inside it (libnickel.so.1.0.0 in the case of the dictionary patch in your initial post). Nothing is done to the rest of the files in the firmware. So there is no need to factory reset.

As far as I understand it, if your Kobo is not having problems, the only time you need to factory reset is in preparation for downgrading to an older firmware version than the one currently installed.

Just be aware that the .tgz file you have created should only be used on a Kobo running fw 4.4.9298. If you upgrade your firmware you will need to repeat the patching process to create a new .tgz using the patch pack from the thread dedicated to patching this new firmware version.

P.S. Is there a reason why you're still using 4.4.9298, which is pretty old?

Indeed this is only the exemple I quoted from this thread; I'm running a 4.6.9995, I'm not sure if it is the fastest and stablest one today.

The patch remove totally the 4 margins? (What must I write otherwise?)

Can I obtain something like thisin the popup window of my dictionary:
