PRS-T1 Changing from original font

Busybox has a lot of commands ready. To view them, just type busybox as root.

To execute a command, add busybox before your command, in your cas this would be busybox umount...

I did not try this, though, so please confirm, if it works for your case.

There is also bash 3.2
You can switch by typing bash as root.

I just read this thread beginning to end once more, as I faced the exact problem as the op.

There is a lot of discussion and some interesting results. However, no one seemed to notice, that the answer to the actual question "How do I get my T1 to changing the fonts?" was given very early in #3 (or did I badly miss something?):

I just reconverted a whole bunch of books and it works fine. You only have to be careful, if there are embedded fonts and you want to keep these. They will get lost by using this method. But for the rest, it's just what I was looking for.

So thanks to rrutkows!

src:url(res:///Sony_Reader/data/fonts/DroidSansFallback.ttf)

Doh! I feel a bit silly now. The only thing to make it display Chinese EPUB I had to do was, open the EPUB and add:

@font-face {
   font-family: "DroidSans", serif, sans-serif;
   src:url(res:///ebook/fonts/DroidSansFallback.ttf);
   }

That's all!

Thank you so much / 谢谢你！

You can also try with src:url(res:///ebook/fonts/SWNMTeb.ttc);

No problem. And thanks for testing it - to this day I haven't tried it myself. Good to know it works.

Jackie, do you know calibre supports a feature that can modify epub CSS when sending to a particular device?

If so it would be nice if we can setup calibre to setup an "alternate" default font for example, always use Amasis with proper italics/bold instead of always changing the font and making sure the bold/italics work in reader UI.

As part of the send-to-device? Not that I know of. The only 2 ways I know of using Calibre are:

1. Put the @font-faces in the ExtraCSS box and do a conversion to epub (even if it's already an epub)
2. Use Tweak epub to explode the epub and copy in the @font-faces manually.

I'm currently using the second option because, as I mentioned before, the first option copies the @font-faces into every html file. This isn't a problem until you want to remove them again, when it becomes a bit of a pain-in-the-proverbial. Also I'd rather not convert epub-to-epub unless I really have to.

Thanks, I was hoping for something automated, but I also would rather go with the manual tweaking of epub than have the font styles on every HTML file in the epub instead of just the main CSS file.

When you do a epub to epub conversion, it saves the original one as ORIGINAL_EPUB. So if you need to convert again, I believe it would use the ORIGINAL_EPUB (without all the @font-face in each html files) instead of the modified ones. If that's the case, wouldn't it solve your concern about the difficulty in removing them?

Manual addition is OK for a few files, but if you have hundreds of files to convert.....

Yes, I do have the ORIGINAL_EPUB option switched on, so no disasters can occur. The aversion to epub-to-epub is deeply ingrained from early disasters before this feature was available

It's a personal preference to try and keep retail epubs as close to the original as possible, but with a few minor tweaks for margins, para-spacing without restructuring the whole epub. It's not necessarily logical although I do try to keep the Calibre library version in a state where it can be transferred to any of my readers. The T1 @font-faces are not suitable for the earlier Sony models or the Pocketbook. For my purposes it's better to add the T1 @font-faces to the epub once it's already on the T1 so I have to manually explode the epub rather than using Calibre Tweak epub.

I never do bulk conversions, too much of a control freak, I'm afraid. I only tweak them just before I read them, it saves re-tweaking when I get a new reader or learn a new trick.

}

Don't need to include a copy of these fonts in each ePUB !
See my previous list of filenames for fonts you can directly reference.
And now that I found this, I know that references outside of the ebook content are possible, only have to find how to reference user-visible integrated and external flash.
I can also stop trying urls that don't begin with res:/// !

My sample reference 6 of the PRS-T1 fonts without embedding them (obviously in 2.3KB) plus a failed reference to a font added to internal flash.

FYI, I already tried res:///ebook/mnt/sdcard (in the sample) and res:///ebook/sdcard as READER root, both failed, will do more tests tomorrow.

Does this work still for the newest firmware (1.0.03.11140)?

@seabee
Thank you very much for your testing!

FYI below from another thread. I don't understand where "internal flash" is to put the fonts, but this is very promising.

Put the customized font file in the location fonts/ in internal flash.

Add the font path in epub : res:///ebook/fonts/../../mnt/sdcard/fonts/font.ttf

Now it works to use the user's font.
