Kobo Patcher

[GeoffR]

Here is the custom line spacing patch for firmware 3.0.0 (0cbc3626b3) on Touch/Glo/AuraHD. I have tested it a little bit on my Glo, it doesn't seem to cause any problems so far (actually it seems to work better than the 2.8.1 patch, which caused problems when reading kepubs):

Spoiler:

Only question for 2.10.0 is, can I use the values from 2.8.1 after ReadingFooter {\n\tmin-height: 70px;\n\tmax-height: 70px;\n\tqproperty-footerMargin etc etc to disable the footer.
tshering did a lot of work there for me and I want to keep the settings.

Nick_1964,
No, this is not possible. Since the original data has changed. The new string is:

replace_xor_6E = 1372BC8, `ReadingFooter {\n\tmin-height: 70px;\n\tmax-height: 70px;\n\tqproperty-footerMargin: 40;\n}\n\nReadingFooter[deviceCodeName="kraken"], \nReadingFooter[deviceCodeName="phoenix"] {\n\tmin-height: 82px;\n\tmax-height: 82px;\n\tqproperty-footerMargin: 15;\n}\n\nReadingFooter[deviceCodeName="dragon"] {\n\tmin-height: 120px;\n\tmax-height: 120px;\n\tqproperty-footerMargin: 20;\n}\n\n* {\n\tfont-size: 16px;\n}\n\n[deviceCodeName="kraken"], \n[deviceCodeName="phoenix"] {\n\tfont-size: 20px;\n}\n\n[deviceCodeName="dragon"] {\n\tfont-size: 26px;\n}\n\n[localeName="ja_JP"] {\n\tfont-family: A-OTF Gothic MB101 Pr6N;\n}`, `ReadingFooter {\n\tmin-height: 70px;\n\tmax-height: 70px;\n\tqproperty-footerMargin: 20;\n}\n\n* {\n\tfont-size: 31px;\n\tfont-family: Amasis;\n}\n\n[localeName="ja_JP"] {\n\tfont-family: A-OTF Gothic MB101 Pr6N;\n}`

Wow, this is with my value of the footer height, and the amasis font ? man can I donate some money to you, you are so, so kind !!

I wait

My line 12 with 2.8.1 is now:

replace_zlib = 1205FF4, `ReadingFooter {\n\tmin-height: 70px;\n\tmax-height: 70px;\n\tqproperty-footerMargin: 40;\n}\n\nReadingFooter[deviceCodeName="kraken"], \nReadingFooter[deviceCodeName="phoenix"] {\n\tmin-height: 82px;\n\tmax-height: 82px;\n\tqproperty-footerMargin: 110;\n}\n\nReadingFooter[deviceCodeName="dragon"] {\n\tmin-height: 120px;\n\tmax-height: 120px;\n\tqproperty-footerMargin: 20;\n}\n\n* {\n\tfont-size: 16px;\n}\n\n[deviceCodeName="kraken"], \n[deviceCodeName="phoenix"] {\n\tfont-size: 20px;\n}\n\n[deviceCodeName="dragon"] {\n\tfont-size: 26px;\n}\n\n[localeName="ja_JP"] {\n\tfont-family: A-OTF Gothic MB101 Pr6N;\n}`, `ReadingFooter {\n\tmin-height: 70px;\n\tmax-height: 70px;\n\tqproperty-footerMargin: 20;\n}\n\n* {\n\tfont-size: 31px;\n\tfont-family: Amasis;\n}\n\n[localeName="ja_JP"] {\n\tfont-family: A-OTF Gothic MB101 Pr6N;\n}`

I installed the patcher v8 on Kobo Aura HD running 2.10.0 and got the bottom margin perfectly with default configs but the fonts are a bit smallish. Any idea how to get rid of the book title on top altogether for full screen reading on kepubs? I am using KoboTouch Extended plugin to covert to kepubs on the fly while transferring from calibre to my device. I know I can use plain vanilla epub for this but any idea how to make it happen with kepubs and increase default font value in Kobo patcher?

Nick_1964,

Everything is ok. I just got a little unsure whether I posted the correct data, since at the moment I am having to many editor windows open at my screen. I checked and it should be ok.

I am not allowed to give karma, perhaps because I did it in the past, I try it later,my girlfriend keeps talking and is now nagging me with a ruler, so I can't make changes, maybe I have to patch her to ?

Sounds like a good idea. I just looked up the Urban Dictionary for "to patch". However, I did not find the meaning I was hoping for.

replace_xor_6E = 1372BC8, `ReadingFooter

with a line for 3.0.0:

replace_xor_D3 = 13BE688, `ReadingFooter


First time I've made use of that old XOR search tool in close to a decade.

It would be great if we could patch 3.0.0 right away for the footer! Just so I get this straight, is this sequence correct?

1) Update reader to 3.0.0
2) Copy libnickel.so.1.0.0 from the KoboRoot.tgz of the 3.0.0 update to replace the one supplied in Metazoa's patch 08
3) Replace the xor statement for the reading footer you have above in the kpg.conf and delete all other css as it may not apply to the 3.0.0 libnickel (although the ones GeoffR posted will work too)
4) Run kpg.exe and proceed with regular patch procedure

Am I missing anything? The only other css statement besides the footer that I was really interested in was the long paragraph bug hack.

I am fighting with the default line height in the Kobo eReader.conf
It is now :
readingLineHeight = 1.35
but one stupid book has a lineheight of 2.0, there is more white then txt, I really hate it to have every book loaded in sigil to change it.
They want to give the ebook the looks of the real book but with this kind of settings i have to overrule them all and calibre isn't working the way I want it, to much settings that have to be all right.
And there is no "kobo simulator" so I have to put the book on the reader, watch it,adjust it..the reader has so much beautiful "switches" to tune the book,but the epub makes ruin them because all of the "nice" settings in the css.
There is no sigil for android to, so I can't hook the reader to my tablet to edit it.. the advantage of a paper book is that you can burn it ritual if you don't like it

It seems you can! Metazoa has released Patcher v09 for fw 3.0.0. What a star

Here is the download link.

Ok using patcher for 2.10.0 in default mode works fine. I got a full screen but for a little bit of space left blank up and down on the screen. So I'm trying to reduce that space and in the "Dragon" part of the code of the first patch I tried to change values 120 120 20 to 60 60 10 but when I do so, the program won't generate a .tgz file so I must assume I cannot change those values as they cause an error. Only problem is I don't see where else on the first patch any "Dragon" code that maximizes full screen use.

So anyone knows where I can change values to decrease even further the blank space up and down on my Aura HD screen ?

Use the code on this post :

does someone know if there exist an epub editor like sigil, running on android ?
