Instructions for patching firmware 3.11.0

I doubt the `Freedom to advanced fonts control` patch can be made to work with this firmware, it will probably require a new patch to be created from scratch.

The current patch involves redirecting one function call to another, and up until now it has worked because both function calls had an identical parameter list. But in 3.11.0 the target function has had an extra parameter added, so it is no longer possible to simply redirect one to the other.

I have test this patch with my HD, it works well. Thanks.

Example for sideloaded "Dark Courier" font:

[Reading]
readingFontSharpness\Dark%20Courier=0.05
readingFontWeight\Dark%20Courier=0.25

The sharpness set by the slider ranges from -0.4 to 0.2 (default -0.06), and weight from -0.2 to 0.8 (default 0.1).

I had a look at this file on my Glo v. 2.8.1. where TypeGenius is working well for my side-loaded font Linux Libertine otf. I did not set any sharpness. I have a unique "readingFontWeight" but with strange -for me- values.

The "Reading "paragraph gives

[Reading]
readingAdobeShowPageNumbers=false
readingAlignment=justify
readingFontFamily=Linux Libertine
readingFontSize=34
readingFontWeight\Linux%20Libertine=@Variant(\0\0\ 0\x87?\x14z\xe1)
readingLeftMargin=4
readingLineHeight=1
readingRightMargin=4

[...]

readingFontWeight\Linux%20Libertine=@Variant(\0\0\ 0\x87?\x14z\xe1)

This was the old format, the change to the new human-readable format happened in firmware 3.3.0 (or was it 3.5.0?).

@GeoffR

Thanks. One reason more to upgrade...

(This could also be caused by a change in the replace replace_string on line 17, post your whole patch here if you can't find the problem.)

Do you think it would work if I use your patch from 3.8.0 and change the binary adresses into the ones of 3.11.0 ? Comment out the ones that don't work ??

I would like to use this opportunity to express my greatest gratitude to GeoffR for everything he does, here, and behind the screens. (you know what I mean GeoffR)

Frankly speaking I do not know how I can survive without you and other people's great work...

It is the meaning of the forum, but in a lot of fora people only think of their own, here people really help.
I like it when not just everyone is calling "use the search" and some people help me before I even asked them something..there is no medaille button/smiley but they deserve it, so it doesn't harm to say thank you, not only GeoffR but all of them who lend a helping hand.
Here I can be myself,no matter if there is a language problem or not,or the question is asked before.
I share the things the people here have learned me,but they must got the credit for it.

For example here is a patch for libnickel.so.1.0.0 that changes Rockwell to Vollkorn (note both names have 8 characters, only tested with .ttf font):

Spoiler:

<Patch>
patch_name = `Modify system font list (Rockwell)`
patch_enable = `yes`
replace_string = C35838, `R`, `V`
replace_string = C3583A, `o`, `o`
replace_string = C3583C, `c`, `l`
replace_string = C3583E, `k`, `l`
replace_string = C35840, `w`, `k`
replace_string = C35842, `e`, `o`
replace_string = C35844, `l`, `r`
replace_string = C35846, `l`, `n`
</Patch>

Thanks for this tip, Geoff. I was able to reclass 7 of my favourite custom fonts as system fonts with enabled Advanced button using this new method on my AuraHD with v3.11. It seems to work OK, only time will tell

I live in hope that someone will have a Eureka moment to restore the full `Freedom to advanced fonts control`patch to its former glory, but in the meantime this is not so bad.

[GeoffR]

I've posted a new `Freedom to advanced fonts control` patch in post #2. It seems to work okay for me, but I don't use sideloaded fonts much for reading, so treat it with caution.

Don't use this patch if you have your device language or book language set to Japanese!

The patch causes a function to be called with an undefined argument. This is a bad thing to do, but as far as I can tell the undefined value is only used when the locale or book language is set to Japanese. Hopefully someone can find a better patch in time.

Thanks, Geoff I'm busy until this evening but I should be able to test it then. Will report back.

I don't like the "Page xx of yy" format for the footer, but I still want to see the "pages", so I'm using this patch:

<Patch>
patch_name = `Custom footer`
patch_enable = `yes`
#
# Changes the footer text with something shorter
# (not sure how it affects translations)
#
replace_string = CAA164, `Page %1 <i>of</i> %2`, `%1/%2`
</Patch>

Now the footer is simply "xx/yy". Similar patches could be done for the percentage and time left formats, I guess.

How can I set the patch to obtain this result? Please help me and my aura hd.

That section of the prologue to Conquistador looks as if the custom footer style is enabled in the patcher.

<Patch>
patch_name = `Custom reading footer style`
patch_enable = `yes`
replace_string = DBDBFC, `ReadingFooter {\n\tmin-height: 70px;\n\tmax-height: 70px;\n\tqproperty-footerMargin: 105;\n}\n\nReadingFooter[qApp_deviceCodeName="phoenix"] {\n\tmin-height: 82px;\n\tmax-height: 82px;\n}\n\nReadingFooter[qApp_deviceCodeName="dragon"] {\n\tmin-height: 120px;\n\tmax-height: 120px;\n\tqproperty-footerMargin: 170;\n}\n\n* {\n\tfont-size: 16px;\n}\n\n[qApp_deviceCodeName="phoenix"] {\n\tfont-size: 20px;\n}\n\n[qApp_deviceCodeName="dragon"] {\n\tfont-size: 26px;\n}\n\n[qApp_localeName="ja_JP"] {\n\tfont-family: A-OTF Gothic MB101 Pr6N;\n}`, `ReadingFooter {\n\tmin-height: 70px;\n\tmax-height: 70px;\n\tqproperty-footerMargin: 105;\n}\n\n* {\n\tfont-size: 16px;\n\tpadding-bottom: 0px;\n\tmargin-top: 0px;\n\t/*font-family:none;*/\n}\n\n[qApp_localeName="ja_JP"] {\n\tfont-family: A-OTF Gothic MB101 Pr6N;\n}`

# Uncomment the replace_string lines of one of the examples below, comment out

# NOT TO ALTER THE LENGTH OF THE REPLACEMENT STRINGS! (Add or remove spaces if

#replace_string = DBDC0D, `min-height: 70px;`, `min-height: 32px;`
#replace_string = DBDC20, `max-height: 70px;`, `max-height: 32px;`

#replace_string = DBDC6A, `padding-bottom: 0px;`, `padding-bottom: 4px;`
#replace_string = DBDC80, `margin-top: 0px;`, `margin-top: 0px;`

replace_string = DBDC20, `max-height: 70px;`, `max-height: 50px;`
replace_string = DBDC3D, `footerMargin: 105;`, `footerMargin: 170;`
replace_string = DBDC58, `font-size: 16px;`, `font-size: 23px;`
replace_string = DBDC6A, `padding-bottom: 0px;`, `padding-bottom: 8px;`
replace_string = DBDC80, `margin-top: 0px;`, `margin-top: 0px;`

I've attached a sample of what I'm using above in libnickel.so.1.0.0.patch to give a similar looking result for the footer. The rest of the page is margin settings and css styling in the epub file.
