PDF compressed when sent with Calibre Wireless Connection

Hi,
I'm trying to send PDF's (that are made of images only) to my Kobo device with Calibre Wireless connection. I drag the PDF into Calibre and then send to device in Koreader latest version. In my Kobo Aura 2nd Edition the file size has changed. Also sometimes I get blank pages later in the PDF.

If I copy the PDF directly using the USB wire it works fine. How do I turn off the compression when sending with Calibre?

This is how I do it right now:
1. Drop PDF (made of images Jpeg) from computer into Calibre Latest Linux Mint 18.
2. Turn on Calibre Wireless Connection
3. In Latest Koreader for Kobo Aura I press connect in Calibre Wireless Connection.
4. In Calibre, click send to device then send to main memory.
5. PDF is now in folder on Koreader, but the size is now smaller.

Why does the PDF change size?

(Update:)
Seems to be fixed for me:
1. Turn on Calibre Wireless Connection
2. Connect Calibre Wireless connection in Koreader
3. When Koreader recognized in Calibre, go to Device then configure this device
4. Cover Thumbnail compression quality set to 99 stops my PDF errors.

file name (pdf) or title in koreader

Hello,

I am a new user of koreader and I wonder if it is possible to have the file name when I am reading a pdf.

Thank you

Two separate 'tap forward' zones?

I'm using KoReader on Pocketbook TL3.
Is it possible to create two separate tap zones for "tap 1 page forward" on the left and right side of screen and invoke menu by tapping in the center? Like it is in Pocketbook?

Because some of my books don't work with KoReader (books from paid service, probably something with encryption), so I have to read them on default PB reader. When I switch between both readers I often get their tap zones mixed up and for example tap in the center for menu while in KoReader.

The zones I would like to achieve look like this in PB:

Clik here to view.


TIA!

Useful tool for people reading CBZ files: CbxConverter

CbxConverter is an easy tool to automate conversion of comic books for reading on KOReader. It's Windows-only, but there's a blurb on the website about it potentially working with Wine.

It allows you to mass convert to CBZ (since CBR files cannot be read on KOReader) and you can also resize the images: right click each job, select "Resize..." and enter an appropriate scaling under "Resize to" (use the Img width column as reference). If you're reading on an eReader, you can also add
Code:

-colorspace Gray
to "before resize" to convert to grayscale, potentially reducing the filesize or improving legibility.

Make sure you change "output extension" to png or jpg, as by default it converts to WebP which KOReader cannot read.

I am in no way affiliated with the creators of this program. If you're reading this, thanks for this software.

Can't Get KSM to Start, Therefore Can't Get KoReader

I had to factory reset my device after it got unplugged abruptly. Prior to that I lived in KoReader, and never used Nickel (I'm including this in case it can simplify my installation process). I have tried just shy of 10 times to get this to work, tediously following the directions (or so I think). Last time (a few years ago) it was a breeze, so I'm not sure what I'm doing wrong.

This thread provides a nice overview of my process:
https://ebooks.stackexchange.com/que...-kobo-aura-one

I too had referenced all the same links the author provides in that post (beside the one for Kobo Aura). This process has failed me three more times today, so if it doesn't work after this one I'm going to factory reset and pray someone here has the expertise to solve this problem. Every time I reboot, it does not load the KSM, just the smiling little Kobo that is part of the Nickel start up process.

Thank you so much to both the developers and kind forum readers that provide this essential support.

Feature request: CBR support

I would like to request to CBR support, I could not find any topic on this, but then again that could be my search skills also :D

My current workaround: (depends on 7zip and unrar)

This is a recursive version: **EVERYTHING ending on .cbr will be converted to cbz**

sudo apt install p7zip-full unrar

Conversion:

Code:

find -type f -iname '*.cbr' -exec sh -c 't="`mktemp -d`";f="{}";unrar x -y "$f" "$t" && 7z a -r -sdel -tzip -mx=9 "${f%r}z" "$t/*";rmdir "$t"' \;
Inplace conversion: (removes original cbr)

Code:

find -type f -iname '*.cbr' -exec sh -c 't="`mktemp -d`";f="{}";unrar x -y "$f" "$t" && 7z a -r -sdel -tzip -mx=9 "${f%r}z" "$t/*" && rm "$f";rmdir "$t"' \;

KOReader flickering issue on the Onyx Boox Nova

I am using KOReader on the Onyx Boox Nova.

KOReader's Android application installs without issues. However, after installation, there is a lot of flickering when selecting menus and highlighting texts. Does anyone know the reason behind this issue and how it can be resolved?

Thanks :thanks:

KoReader freezes/no longer works on Kobo Aura H20 Edition 2

I own a Kobo Aura H20 Edition 2 that had been running KoReader for several months with no issue. I tried to update the screensaver folder with an image (which I've done many times) but this time KoReader wouldn't launch, whenever I would select the KoReader image from My Books (which would launch KoReader) it just displayed an image instead of launching.

Okay, so I'm like whatever I'll reinstall everything. I did a factory reset on my Kobo and followed these instructions I saved:
Quote:

1) Factory reset
2) Log into wifi and when asked log into Raku kobo account

3) Follow the following links to install KoReader
(FROM: https://github.com/koreader/koreader...based-on-kfmon)


i. Download the latest install package for KFMon. (KFMon-v1.2.15.zip)
https://www.mobileread.com/forums/sh...d.php?t=274231

ii. Extract the full content of this archive into the root directory of your device (i.e., not under any subdirectory).

iii. Download the latest release of KOReader (e.g., koreader-kobo-arm-kobo-linux-gnueabihf-v2019.03..>)
http://build.koreader.rocks/download/nightly/

iv. Extract the koreader folder of the zip into the .adds directory of your device (a directory which may have just been created by KFMon's archive).

v. Eject & unplug your device. Nickel should then appear to be processing a book, before restarting to process an update.


5) Install dictionary via \.adds\koreader\data\dict

6) Install screenshots via \.adds\koreader\screenshots

7) Install fonts via \.adds\koreader\fonts


The problem is, before Step 5, KoReader launches but it freezes, it doesn't let me click anywhere. When I reset the device it goes back to the original Kobo software and when I relaunch KoReader, same thing, I tap but nothing happens. I do remember the first time I went in there after the reinstall it said something like "still processing". At one point I think it said "unable to launch something.ssh".

What am I doing wrong? Did anything change?

What are the nicest looking fonts you think would look good on the koreader?

Any suggestions? Maybe Amazon's bookerly?

Two issues with KoReader: Style Tweaks feature & Status Bar

Sorry for the 3rd topic I created today here, just had to factory reset so trying to get things working as they were. Two questions I had:

1) Under Style Tweaks > Text > Ignore all 3 Publisher specifics, can you set this up for EVERY book instead of just 1 book? I want to set it by default to ignore the publisher specifics each time so I don't have to do it for every book

2) Under Gear Icon > Status Bar > Battery Status shows but even though current page and current time are checked, they do not show. This I know is possible, any idea why it's not working?

Transfer via Wifi Calibre - what folder to be imported in Kobo ?

Hi,

I am using the latest KoReader and i am transferring files wirelessly using calibre directly onto /mnt/onboard directory.

I can open them with KoReader, but in the original Kobo interface they are not seen.

How can i import .epub files via Calibre wireless in Koreader, AND be seen as well in the original Kobo interface ?

Thanks !

Just wanted to say thank you to NiLuJe and team!

Just wanted to thank you guys for all you do, and how much your help has made reading more enjoyable for so many people.

So :thanks:

koreader-cervantes dependencies appear to be corrupt

I've recently updated the version of koreader on my Cervantes 3 (there's some bugfixes in there that I needed as my hacked alternatives were... not good), and I see there's some new .debs to install in https://www.mobileread.com/forums/sh...d.php?t=311571.

Unfortunately, it appears that the iproute2 dependency is corrupt; dpkg -i complains when it attempts to decompress/hash the package.

Could someone please either update that dep *or* please point me to how you're building deps for the (now gone) variant of wheezy the Cervantes 3 runs?

Cheers!

Questions about the best settings for readability

Hi,

First off, thanks for developing this software. I don't know the terms of the settings of the koreader like what does it mean 'font hinting' and its settings- off, native, auto. Which provides the best experience of reading? Same thing applies to the 'font kerning' that which setting is best? Why is it there fast and best options? I just can't make out the terms

Thanks in advance

Chapter Progress in Book Status

Hello,

I just installed KOReader on my Aura One and think it's great! I tried it a few years ago on my original Kobo Touch but it is so much better now I'm going to use it as my regular reader. Thanks so much for all the hard work.

I generally like to read in full-page mode (no status bar) and one thing I miss from Nickel is being able to tap on the screen to see my book progress. The closest I've come setting the bottom right tap to bring up the Book Status, which is pretty close, but I would really love to be able to see my chapter progress in there. Is there anyway way to configure this?

Alternatively, is there anywhere else to see chapter progress? I've only ever seen it shown in the progress bar (with the chapter markers).

Thanks again for the great software.

Pocketbook (Inkpad 3) clock stopping

Hello, I'm just curious whether anyone else has experienced this: since several weeks the clock in my PB-IP3 (with the latest fw) does not work, time does not move forward at all, it only gets actualized when I sync the device, then it remains in one place again. I haven't seen this reported on any PB related forums, and the only thing that has changed on my device was that I have updated koreader, so I suspect it has something to do with this issue. BTW this behaviour has started around the time this (otherwise very cool) fix has been implemented: https://github.com/koreader/koreader...251c3f25dfc6f8
Have you seen anything like this? Were you able to solve it? I don't want to report an issue before I am sure it really is koreader-related, but I also don't want to make a factory reset without believing it could really help.
Thanks for any answers!

What is "floating punctuation"?

Hi
I searched on the Internet what "floating punctuation" means but found absolutely nothing and when I enable it, I cannot see any changes through the text except for the number of pages. Should I enable or disable it for the best reading experience? Also, what's the default setting of it? Checked or unchecked?

Can I ask for dictionary addition for Turkish?

Hi

There are plenty of dictionary of various languages but there I couldn't see any Turkish-English dictionary. Is there any possibility or a way for you to add at least one Turkish dictionary? I just know that babylon gives free dictionary but it is in .bgl format which I couldn't convert it to stardict one so couldn't use it. And also I will add a dictionary scanned in .pdf format. If you might add these two it would be great

Want to check if custom fonts applies to txt files

Right, so do fonts and custom fonts work on txt files (extension .txt) in KOreader?

I've been trying all my fonts and custom fonts on the txt files I have but the font that's been showing up is always the same one no matter how many I've changed.

Looking for Screenshoots of KFMon

Hi,

As far as I understand that the KFMon is the Koreader working on Nickel right? I wanted to install it but couldn't find any images. Can you send your KFMon installed Koreader please?

Thanks.
