Instructions for patching firmware 3.19.5761

Thanks, but I am not fully happy yet. How could I make this space smaller? Which value should I modify?

You would need to reduce the min-height and max-height values further, enough to allow room for one more line of book text to fit in the gap. And if that results in the page number text being clipped then you would also need to reduce the caption font size too.

If you want to see how much space the footer is occupying, use the margintest.epub test book. This will let you see how much of the gap is due to the size of the reading footer, and how much is a result of your choice of other settings.

A more precise approach: The screen height on the Aura is 1014px, so if you subtract from that the size of the top @page margin and the size of the reading footer, then divide by the number of lines of book text you have on the screen, you will get a line height L and a remainder R. You would need to reduce the footer height by a minimum of L-R pixels to make the gap large enough to fit in another line of text at those settings.

Edit: Also beware that the publisher often sets the top @page margin in the book, so if you want the bottom gap to be consistent for all books then you would either need to edit the books and remove page margins from the CSS and XPGT stylesheets before sideloading (The Modify ePub Calibre plugin is useful for doing thsi) or else investigate the `ePub fixed/adjustable top/bottom margins` patch to override the CSS @page margin and possibly the `Ignore ePub book Adobe XPGT stylesheet (page-template.xpgt)` patch too. Also some publsihers add a small paragraph margin which will cause the bottom gap to vary depending on the number of paragraphs on the current page, and the only way to avoid that is to edit the book and remove the paragraph margins. The smaller you try to make the bottom gap, the more likely these other factors are to upset it. In the end you might find it less hassle just to adjust your line spacing, font size, etc. a little to minimise the bottom gap each time you start reading a new book rather than try to find custom settings for the `Custom reading footer style` patch to suit all situations.

Another thing is a smaller font and/or smaller line-height.

[LittleBiG]

Thanks, it was very thorough and useful.

None of the existing patches in this thread can help with that.

The basic problems are that Vietnamese is not one of the languages officially supported by the device UI; and the UI only uses the built-in fonts, none of which fully support Vietnamese; and the built-in fonts are encrypted so we can't change them.

Some languages that are not officially supported such as Russian, Hebrew, Arabic still display the book titles correctly in those languages, but I think that is because there is support for those languages in some of the built-in fonts. I don't know if anyone has worked out how to make the UI use a sideloaded font yet.

However I know little about the dictionaries, I only read in English and hardly use them, so maybe someone else who knows more will have some ideas on how to do it.

Edit: I see you posted in the Modifications for bad eyes thread too. Do as tshering suggests -- make sure you have Vietnamese fonts sideloaded and working correctly -- you might find that some things will work without any patching needed.

thank you a lot, i was try but not things can change it, just a little bit annoying when i use dictionary at my phone )

[Number9]

Thank you so much for this patch GeoffR! My first one, and all went well!

[meeera]

I just finally bit the bullet and patched my H2O - thanks Geoff!

The finer brightness control and advanced tweaks on sideloaded fonts are the bomb.

[Josieb1]

I've just patched for the first time and it was quite scarey tbh. I only changed the default no to yes for the 'Freedom to Advanced Font Controls' as thats all I wanted, I like Bookely but wanted it darker.

Thanks to everyone who is involved for the instructions which even a code phobic like me could manage

Gracias!

Hi,

When I use "Custom kepub default margins" patch, I can't set margins at all with Kobo Glo HD. They stay at a minimum value. I didn't have that problem with Kobo Glo.

Are you using full-screen mode?

Just beware there is a new bug in firmware versions 3.19.xxxx that causes the margin adjustment to stop working in KePubs after you have paged past a chapter break. The only work-around seems to be to close the book and open it again, and then adjust the margins before you pass the next chapter break.

This bug is not related to the patch, it happens on an unpatched device too. It only affects KePubs in full-screen mode.

[GERGE]

Didn't know that, thanks.

I am using full screen mode and just started reading KePubs. They seem to be much faster in Glo HD than ePubs, and apparently they fixed hyphenation greatly.

Thanks again.
