I did.

This is at least what patchit.exe does, and until now I did not see any negative effects. Strictly speaking, I do not think the zeros are necessary (or have any effect at all) in this case. By the way, if the new compressed stream turns out to be longer than the original stream, patchit.exe tries again with compression level set to maximal.

I do not have a kobo with me. If anybody wants to do some experiments along that lines:

For testing purposes, I would remove in the newpart section, lines that refer to devices other than the one you will test with, in order to make sure the resulting zlib stream is not longer than the original one.

Thx for \x00 info ;-) I updated my python script to patch nickel and tested margin-top:100px in body but seems doesn't affect.

[pipcat]

If bigbless or someone else wants to try css changes in nickel, the attached python scripts could be useful.

Tool to patch compressed streams inside nickel.
- Copy your nickel file from your firmware to this folder.
- Execute python extract.py to extract all compressed streams.
- Browse extracted/ folder and view .css files to find out what you want to change.
- Copy files you want to change to folder modified/ and change what you want.
Note that resulting file after compression could not be larger than original one.
Remove comments or code related to other devices if you need to shorten.
- Execute python patch.py to create a nickel-modif with your patches.
Check messages to verify modifications are well done.
- Execute ./publish.sh to create KoboRoot.tgz and copy to folder .kobo/ in your device.

Ok thank you for the help, I would like to try both options but I'm a total noob and don't know what to do for starters is there a tutorial on how to backup everything in case I mess something up and clone the sd card or something else?

I'm willing to do this and in case it doesn't work I don't mind changing epubs so that the top margin allows me to read them on the ebook.

Thanks

As for backup, you can simply make a copy of the user partition (this is what you see when you connect via usb to the pc). As for the other partitions (which you cannot see) it is highly unlikely that you mess something so up that resetting the device cannot help you.

As for the larger top margin in epubs, you can try it without any danger. Have a look at Instructions for patching firmware 3.19.5761. Read the instructions in order to get a general understanding of how it works. Then open libnickel.so.1.0.0.patch. You are interested in `ePub fixed/adjustable top/bottom margins`. Find it and enable it (patch_enable = `yes`). Then find the line

#replace_string = B8A1A4, `%\01`, `2\05`

uncomment the line (by removing the #) and choose a greater value. I tried for instance

replace_string = B8A1A4, `%\01`, `4\05`

This gives a pretty large top margin, but maybe it is still to small for you. Maybe you start experimenting with `6\05`.

Hello I've tried with :

replace_string = B8A1A4, `%\01`, `9\05`

but there is still 1 and half line that cannot be seen the problem is when I try to test with values of 2 digits like this:

replace_string = B8A1A4, `%\01`, `10\05`

it gives and error:

Is there a way to do with 2 digits replacements so that I can get the KoboRoot.tgz file?

If you don't need to replace left/right margin in this same patch, you can get one more digit. Example with 150px:

replace_string = B8A1A4, `%\01\0p\0x\0 \00`, `1\05\00\0p\0x\0 `

Css code: @page{margin:%1px 00px %1px}body{ will change to: @page{margin:150px 0px %1px}body{

Thanks a lot it worked and now it transitions correctly, there is one last thing that I wanted to know if possible also to edit by patching lines it is the definition as you can see it popups most of the time at the top, and I can't see the full translation.

Is there a way to patch that so that it appears at the bottom?

I've included photos in attachment

There is a patch to change dictionary frame size. Maybe you can customize it to your needs.

Hi, I'm update my kobo Glo to 3.19.5761 FW
I had been patch, and replace font to Arial.
The problem : In Dictionary view is not Arial.
How i can change the font in "Dictionary view"?
Thanks all!

In libnickel.so.1.0.0.txt there is an example, look for "name=Dictionary (Georgia)." Instead of Georgia you can take any font name. Do not forget to enable this patch (enabled=false), and disable the patch named "Dictionary (font chosen by software)."

[huuduc1kk2]

Thanks "tshering" for quick reply!
I got it!
Now with this file you can change to a Unicode Font: Arial.

Since there seems to be a certain interest in investigating the css blocks of nickel and libnickel.so.1.0.0 (cf. this thread), I publish those css blocks that I could easily find (that means: I do not claim that all css blocks are included).
