PRS-T1 Changing fonts and CSS on PRS-T1 like PRS+?

Good luck! I don't know whether you already read one of the other threads, but if you manually add a statement (credit to snarkophilus)

@import url(res:///ebook/fonts/../../mnt/sdcard/css/my.css);

to the top of the css file in an epub then the T1 will use everything in the int.mem user-accessible file [intmem:]/css/my.css (which can contain all the @font-faces and any other custom css) when displaying the epub. If you get the contents of your custom css file correct it won't interfere with the standard (or your fixed) select-a-font feature. The drawback is that, so far, the only way to edit each epub is manually. If this @import could be part of the Sony reader app generated css, this may be a way forward. Then all that is needed is another app on the T1 which will display a list of css files in directory [intmem:]/css and when one is selected copy it to /css/my.css -- instant custom font change. It does work, I've been using it. It's a bit like the way the PRSPlus custom firmware works on the earlier Sonys.

Alright, in that case i guess a package that just replaces the reader application (or installs another besides the original, but without the rest of the root) might be a good thing. I'll make a package and do some testing to make sure it doesn't break anything

Yes, I've seen that it's possible to access fonts outside the internal fonts folder. What I'm working on is intercepting the calls to the methods that generate the CSS and the font selector and replacing the fonts with ones specified in a settings file on the internal storage. I'm about half-way there.

More importantly YOU FIXED THE GODDAMN BUG BY CHANGING TWO LINES OF CODE AND SONY HASN'T FIXED IT THEMSELVES YET???!???one!?

EDIT: Also I fear it crashed shortly after I started fiddling with it, so it might not be there quite yet.

It was more like 24 lines of smali assembly, to be honest, but they look like they were generated from one or two lines of Java. I guess maybe they never realized small-caps was causing trouble?

I've never been able to make it crash, I'm afraid. Does it happen every time, or when you do something in particular? If possible, it would be great if you could post the log around the time of the crash (`adb logcat` if you have adb installed and configured, or `logcat > /mnt/sdcard/log.txt` in a terminal on the device).

It seems to crash every time I try to open the Settings menu (menu button -> More -> Setings) from within the Reader app.

Confirmed, thanks. Seems like the Reader app isn't as lenient as the home screen when it comes to living in a separate package from the rest of the Sony apps (i.e. being installed next to the original Reader). I'll post a package that replaces the original reader as soon as I know it doesn't cause any catastrophic failures

[Morkl]

Wow, my initial guess as to what was the problem was off by miles and now I've been trying to make a working packaged that replaced the original reader for hours, to no avail. Beh.

Anyway, here is a new package, in which Menu->More->Settings works:
http://morkl.se/reader/readermod_v1.1.zip
And here is one that doesn't requires root, but just installs it as a regular app and removes the default app preferences (basically the same as a root package but with the modified Reader app instead of the system utilities and launchers and superuser thingamajigs and whatnot):
http://morkl.se/reader/readermod_v1.1_noroot.zip (install by connecting reader to PC, enter Data Transfer Mode, then doubleclick flash_reader.bat)

N.B. these do not replace the original Reader, as i anticipated in my previous post. Doing so seems to be a lot more tricky than I thought, since it would the require a bunch of other system apps to be replaced as well.

Coming up next: The progress I made during my lunch break today

[Morkl]

...and here it is! Stock Reader with custom fonts in the select-a-font-thingy (and the italic/bold-fix, of course).

Fonts are specified in /sdcard/fonts/fonts.xml, and if that file is not found or cannot be read it falls back to the stock fonts.

"Screenshots" attached, with exaggerated fonts to make it clear that it works (the reason "Bold italicized text" is not italicized in one of the images is that I had no bold-italic file for that font, so i set the bold file as bold-italic).

As you can see, the "Selected Font Type" thingy does not show the custom font name for now; it consists of a bunch of hard coded button resources and so requires a bit of extra work to replace.

File: http://morkl.se/reader/readermod_v2.zip (contains loose apk as well as installer for non-rooted devices; and fonts folder with sample settings)

[soseono]

Wonderful!!!!!!! One quick question: Is there any way to change the "Original" font setting as well? Or is it simply impossible to do so?

[quisvir]

Great work once again Morkl! Next step... selecting custom css?

[Rand Brittain]

That is truly inspired coding. You have taken the PRS-T1 from "not a good choice because of disqualifying software bugs" to "quite a good choice."

It is sad that Sony couldn't do that on their own, since it took you about a day, but you, you get the right to be happy.

[jackie_w]

@Morkl,

Wow, such rapid progress!!! Thank you

Now, please don't take this the wrong way. For us clueless non-Android types, if we have any problems after installing the customised reading app, is there a way to get back to standard Sony firmware?

Edit: I decided to risk it, anyway. Tried to run from the install_noroot folder (I'm using a WinXP PC). The messages coming up in the CMD box appeared to be copying the files to the T1, however it doesn't seem to have completed the process.
The script.log file contains the following:

Starting ./update.sh
./updates/data/app/EbookReaderMod.apk: MD5 check failure [ != 8c740786ff94bc488b623b68b3fef788]
clean_exit

I tried a second time, but unfortunately with exactly the same result. Any suggestions?

This is the content of the checksums file. By any chance, is the problem simply that the name in there is EbookReaderMod.apk when it should be EbookReader.apk?

8c740786ff94bc488b623b68b3fef788  ./updates/data/app/EbookReaderMod.apk
f078951460edbc1b7d7f4f06aa63dac4  ./tmp/do_update.sh

Original font is a special case; the device doesn't generate any CSS for it (instead using the renderer's default CSS). It might be possible to circumvent the check though.

That is definitely what's next for the Reader app. I'm gonna take a small break and clean up my code first though

That's the thing I like about open (or in this case closed but rootable) systems, where anyone with the know-how and time to spare can fix things. Now, if only Sony would put up a repository where I could post my patches...

Yes, there is a "restore" package that flashes back the original firmware and an "sd rescue" package which does the same from a memory card even when unable to connect the device to a PC.

And the problem: my bad. I forgot to change the name of the file. Either change EbookReaderMod.apk to EbookReader.apk in the checksums file or rename the file EbookReader.apk to EbookReaderMod.apk or redownload readermod_v2.zip, because I have fixed it now

Many thanks also from my side! Unbelieveable, how fast this is developping.
Really looking forward to the version with custom css á la PRS+.

@Morkl,

This seems to be working OK now A couple of (probably dumb) questions, please.

Firstly, after the update I have some new files in int.mem

1. dir - /updates
2. file - PRS-T1 Updater.package
3. file - script.log

I'm assuming item 3 can be deleted. Are items 1 and 2 now part of the firmware or are they temp files which can also be deleted?

Secondly, when I open a book I now get the choice to select either the new modified reader app or the original Sony app. If I chose the option to set the new app as default, would I be able to reverse the decision afterwards or would I need to use the restore package then reinstall the mod to get the either/or choice back?

Once again, many thanks for your efforts, karma heading your way

Any chance on supporting hyphenation? Nook does (rumor says they are using different version of Adobe SDK)? Worth checking?

They can all be deleted; the only new stuff that is needed is the fonts folder, and it should only be needed when using custom fonts.

I was just thinking of that last night. I fear it may be rooted deep withing native libraries, but it is definitely worth looking into.

[treadlightly]

Thank you! I tried this out and it worked very well! If we're adding to the wish list, I'd like to vote for justification
