PRS-T1 Changing from original font

[salines]

Thanks jackie_w.
I thought that I make something wrong....

At the first time I read that outside epub fonts work (older ereaders than T1) - I decided to use this method - but I have a T1.... So now I know that this doesn't work... What a pity!

It doesn't work yet ! It's still possible that an unknown (today) external resource path would solve the problem.

[salines]

Maybe we (who wants to use this method) should make a separate thread to show which paths we tried. So we all don't have to try the same paths.

[jackie_w]

These are two I tried ... which failed

Internal mem: src: url(res:///mnt/sdcard/fonts/xxx.ttf)
microSD card: src: url(res:///mnt/extsd/fonts/xxx.ttf)

For embedding the fonts, I've been using Amasis. That adds about 30-35k to each ePub for each font regular, italic, bold, and bold italic. Not so bad.

+ the time for embedding the fonts.

Maybe I have time to play at the weekend with the paths.

I tried to make an EPUB containing the following stylesheet and paragraphs referencing the corresponding classes (<p class="a">ABC...</p>...) with Sigil, but only the first one (class = "a") was successful, all the others falling back to the default PRS-T1 serif font. I'm sure that /system/fonts/FrutigerNeueLTW1G-Regular.otf exist on the PRS-T1 because I extracted it with ebook_msc.exe (command line: ebook_msc.exe name "PRS-T1" get /system/fonts/FrutigerNeueLTW1G-Regular.otf FrutigerNeueLTW1G-Regular.otf) and embedded it in my test ebook in Fonts subdirectory (in Sigil, at the same level as the Styles directory that referenced it, hence the ../Fonts in MyFont1 definition).
I added a fonts directory containing comic.ttf on my PRS-T1 (=> /mnt/sdcard/fonts/comic.ttf references)
Actually, all references outside of the ebook itself seems to fail

The PRS-T1 have the following font files in /system/fonts folder:
AmasisMTW1G-Bold.otf
AmasisMTW1G-BoldItalic.otf
AmasisMTW1G-Italic.otf

Thanks for testing.

That's no good result.....

@seabee,
Thanks for trying. We need some divine inspiration...

The last contact I had with porkupan/boroda he was aware of the problem but had not spent any serious effort looking for a solution, I guess because he was concentrating on his 'root the PRS-T1' project. The 2 options I mentioned in post #19 were based on his info.

It's quite possible that rooting the PRS-T1 and using one of the other epub readers (e.g. CoolReader, FBReader) is a different solution to the problem. However, not everyone will be confident enough to go this way. I have previous experience using FBReader because it is one of the 2 defaults on my PocketBook 360 but I hated it because it ignores most of the epub's css styling - other people love it for exactly the same reason

Like you, I hope one of the technical gurus will take an interest in solving the T1 custom fonts problem at some point, but until then will have to make do with physically embedding fonts in each and every epub to get custom fonts with all Bold and Italics intact.

[seabee]

I finally succeeded for references to any PRS-T1 integrated font !

for exemple:
@font-face {
font-family: MyFont1;
font-weight: normal;
font-style: normal;
src: url(res:///ebook/fonts/FrutigerNeueLTW1G-Regular.otf);
}

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.

@seabee,

This is encouraging - hope you find the magic 'external location' soon
