For #1, it's not specific to just the Home screen. I'm more interested in changing the font for the menu selected on the Home screen (My Books, My Collections, My Articles, Settings, Activity, etc...).

For #2, if enabled, does that remove everything else currently displayed on the Home screen (i.e. current books being read, My Books, last opened collection, Recommendations, etc...)?

I think we just cross-posted. See my reply above yours.

OTOH, I do believe that if you buy something you're allowed to do whatever you like with your personal property, so I'll PM you.

Hello everyone.

In libnickel.so.1.0.0.yaml, there is this section

KePub stylesheet additions:
  - Enabled: yes
  - Description: Makes room to add some additional CSS to the default KePub stylesheet.
    # See replacement CSS below for examples.
  - FindBaseAddressString: ".KBHighlighting, .KBSearchResult {"
  - ReplaceString: {Offset:   0, Find: ".KBHighlighting, .KBSearchResult { background-color: #C6C6C6 !important; } \t",                                                                         Replace: ".KBHighlighting,.KBSearchResult{background-color:#C6C6C6!important}.KBSearch", MustMatchLength: yes}
  - ReplaceString: {Offset:  76, Find: ".KBSearchResult, .KBAnnotation, .KBHighlighting { font-size: 100% !important; -webkit-text-combine: inherit !important; } \t",                          Replace: "Result,.KBAnnotation,.KBHighlighting{font-size:100%!important;-webkit-text-combine:inherit!important}.KBAnnotation[writingM", MustMatchLength: yes}
  - ReplaceString: {Offset: 199, Find: ".KBAnnotation[writingMode=\"horizontal-tb\"] { border-bottom: 2px solid black !important; } \t", Replace: "ode=\"horizontal-tb\"]{border-bottom:2px solid black!important}.KBAnnotation[writingMode=\"ver", MustMatchLength: yes}
  - ReplaceString: {Offset: 290, Find: ".KBAnnotation[writingMode=\"vertical-rl\"] { border-right: 2px solid black !important; } \t",      Replace: "tical-rl\"]{border-right:2px solid black!important}.KBAnnotation[writingMode=\"vertical-lr", MustMatchLength: yes}
  - ReplaceString: {Offset: 378, Find: ".KBAnnotation[writingMode=\"vertical-lr\"] { border-left: 2px solid black !important; }",          Replace: "\"]{border-left:2px solid black!important}/******************************************/", MustMatchLength: yes}
    #
    # Replacement value: CSS string of exactly 44 characters in length:
    #
    # Example 1: Make full justification the default:
# - FindReplaceString: {Find: "/******************************************/", Replace: "body{text-align:justify                    }", MustMatchLength: yes}
    #
    # Example 2: text-rendering:optimizeSpeed: Disables kerning, but fixes some
    # rendering problems that affect fully justified text.
# - FindReplaceString: {Find: "/******************************************/", Replace: "body{text-rendering:optimizeSpeed          }", MustMatchLength: yes}
    #
    # Example 3: text-rendering:optimizeLegibility: Enables ligatures, but causes
    # some additional rendering problems for fully justified text.
# - FindReplaceString: {Find: "/******************************************/", Replace: "body{text-rendering:optimizeLegibility     }", MustMatchLength: yes}
    #
    # 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.
# - FindReplaceString: {Find: "/******************************************/", Replace: "#book-inner{font-size:1.5em                }", MustMatchLength: yes}

Is it enough to change from "yes" to "no", or must I do other things in that section?

It won't do anything unless you uncomment one of the lines at the bottom or add your own.

To jump on the bandwagon, uncommenting the OptimizeLegibility bit gave me an error:

'Error: could not apply patch "KePub stylesheet additions": line 1207: inst 10: FindReplaceString: FindBaseAddressString: FindBaseAddress: could not find bytes'

I'm aware of the spacing issues (old COBOL head here ), but this is something different I think.

I checked

          |         FindReplaceString("/******************************************/", "body{text-rendering:optimizeLegibility     }")
          |           FindBaseAddressString("/******************************************/")
          |           ReplaceString(0, "/******************************************/", "body{text-rendering:optimizeLegibility     }")

Works...

Lay out this piece of the patch.

How did you do this? I can't bring it to work, it only throws:
Error: could not apply patch "Never sync dictionaries": line 1543: inst 2: ReplaceBytes: could not find specified bytes at offset


EDIT: Nevermind, got it now, using the code from geek1011's site.

Hi, succesfully updated my old Kobo Glo HD firmware version with this new one.

Years ago I patched 3.xx version for screen refresh extension, now I see current new default refresh max 10 but no patch for extension. Some help for this?

Hope this is the right place to post, if not please help... sorry for bad english...

Thanks in advance

Enabling which patch(es) gets me the most text in the top and bottom areas when reading? In other words, I want to have text go as high up and as low down of the screen, so that text will be almost "kissing" the black plastic frame.


In libnickel.so, there's
-- ePub fixed top/bottom margin
-- ePub disabled built-in body padding bottom

Another question. in the same file (libnickel.so), there's a pathc called "Force user line spacing in ePubs (part 1 of 2)". The description says that enabling it will "spoil the formatting in some books".
What formatting will be spoiled? And what books will be affected?

The only thing that could be spoiled is dropcaps.

There's also patches for adjusting the spacing/font size of the header/footer and you can recover some space there.

Also see https://pgaskin.net/kobopatch-patche...tch-13651.html for a demo of most of those.

I've uploaded the nickel.yaml file. Because mobileread rejected the "yaml" extension, I added ".zip" even though it's not a zip file. Simply remove the dot-zip part and open in a text editor. Thanks.
