Many pdfs fails to render in easy mode if I am in landscape orientation when trying to open it in single page. If i close the document and change orientation to portrait then reopening the same document works.
Also works if i am in landscape but use the new double pages feature

It seems that if if you are in double page mode, the "invert colours button" also goes to the next couple of pages.

I am experiencing this (in real time) on Librera beta 7.0.56, on the Onyx Boox Max Carta (Android 4.0.4). (At the moment cannot test the new beta, being away bound on mobile)
On last boot session, I was reading a 150MB (made of scans) PDF; having booted the device today,
-- when I open Librera, it tries to load the last book but hangs forever in "Loading..Please wait";
-- so I open a new book from the launcher, but still hangs forever in "Loading..Please wait".

I am not sure how can I further assess

Now the font and the size are global, can it be one variable for each file?

It may be important to have zoom control also in easy mode,
or at least a "fit to screen" option (please also see forthcoming bug notice about books that are opened with the wrong zoom).
I suppose a "pinch" function exists, but some screens are not multitouch (for example, "wacom-like pen only controlled").

Great project guys a nice combo of popular and powerful projects and as it in continuous development it will definitely help a lot of devz and take over project like fbreader as open source fbreader is not being developed any more so yeah Librera will definitely help alot of people's to speedup the job

BUT, as you mentioned it require Eclipse so the issue is now a days we all are using android studio for all of our project so, ether if you can Add some better documentation on this or If it is possible to migrate from eclipse to Android studio that would be great.

And Thanks for such a great contributions to open source community.

Keep up the Good work.

“what is new in beta 7.8.38”应该从“preferences”界面下删除，转移到“product:beta 7.8.38”界面下，因为它是属于对产品的说明，并不属于阅读设置。仅保留“what is new”就可以了，后面的版本号应该被删除。因为版本号会随着更新而有长度变化，不利于界面美观。

The default sort criterion for the "starred" documents browsing view is by "date of starring", which is very good, but some users maybe would like to be able to switch to sorting by name, or (what do you think?) by folder and filename.

Probably not urgent or important, but just for completeness.

It would be very useful (and consistent with the other documents browsing tabs) to have the mode selector (MODE_LIST, MODE_LIST_COMPACT, MODE_GRID, MODE_COVERS) also in the "Starred" documents browsing tab.

Thanks!

Hello,

First, fantastic software, I've been looking for a replacement for the ageing MoonReader and I switched within ten minutes of finding things. I am very impressed.

The biggest thing that impressed me was true auto-scroll, not 'get to the end of the chapter and move to the next one' auto-scroll that MoonReader has. Now I'd like to make my reading experience truly 21st century and get rid of any distractions when reading. I don't know CSS that well (I don't even know if it is a CSS thing or not) but is there a way to remove page markers, and get rid of any whitespace between the end of one chapter and the start of another?

Animation in general - "Simple scroll animation" in the preferences - should be disabled by default on slow refresh screens.
This is first of all for electrophoretic displays.
The one I have here shows a refresh rate in 'dumpsys' of 0.001, which is far from true; so-called 'A2' mode looks around 8fps, and I have seen videos of new EPD screens that look capable of around 16fps.
Probably, a display with a rate below 20fps could be considered "slow" (?).
The point is especially important for EPD display: pixel switchi in normal mode is graphically messy and uses battery inefficiently in animations

Hi, I just installed the new beta 7.1.30,
the first thing that appears is a notification window that says that a new beta version is available.
But
-- 7.1.30 is the latest
-- and anyway, the second device I installed it to had no internet connection, so it cannot know...

Hello, I am very interested in this project.
Do you plan to support additional Microsoft formats?

This is an issue that was also on the old versions of "PDF Reader"... To overcome it, I used to upload documents with margins already cropped.

The problem: open a PDF in "Advanced mode", toggle the "crop white margins" icon. The rendered page will appear jagged, blocky and uneven, as if scaled from a much smaller rendering and/or using a sketchy algorithm ("nearest neighbour" etc.).

In my opinion, this issue should have a high priority

The file mentioned on the official website is archived.

Could you paste a tutorial in English here or somewhere.

I suggest to disable the toc icon in documents with no toc. Instead of opening a blank toc window (and closing it), could be showed a toast to inform that the document has no toc. The toc icon could be disabled and with a different color (grey) to be clear it is disabled.

При долгом тапе на книжке отключается обрезка, хотелось бы иметь возможность убрать это поведение. Это наблюдается в расширенном режиме на 7.2.20 - 7.3.5 Android 7.0
Наблюдается в pdf и djvu

Does the library support CFI?
Link : http://www.idpf.org/epub/linking/cfi/epub-cfi.html

Thank you so much.

Setting a different view in Recent tab other then list view is not remembered if you restart the app.
It shows books always in list view even if your last view was grid or cover or compact view.
It should remember the last view setting similar to the other tabs (library, starred)

I think it would be interesting to have a functional, to support the formats word (doc, docx) and openoffice

The "Go To Page" window, using page thumbnails to go to a page, should probably use double-width cells when in "double page" mode

In the list and grid view of the book selection tabs, a heuristic method is used to identify "author (editor, etc.)" and "title (subtitle, etc.)" from the filename, when they are not available as metadata: the space-dash-space, ' - '.

Problem: not all filenames use the "author - title" syntax,
for example 'Book about something, The [Publishing House - Smith, J., 2000]'.
In this case, the "Author" is taken to be 'Book about something, The [Publishing House'
and the "Title" is taken to be 'Smith, J., 2000]'.

Proposal: add a string field with an expression such as
"%a - %t"
The above defaults to what you are doing now. If the user modifies the expression, for example, as
"%t [%a]", then the split would be correct for the example I gave above.

(I mention this issue in another post, but here it is better defined).

When I select a word in a sentence I want the application to automatically select a whole sentence or paragraph.
Tks.

Greetings,
some documents (especially scanned documents) may not be fully contrasted, ranging as images from light grey to darker grey instead of white to black.
It would be nice to have a contrast enhancer, to render the pages flattening colours towards the extremities of black and white. Example curves:

This is especially useful on EPD displays, where you really have "light grey to dark grey" in reality - some contrast is lost because of the current hard limits of the technology...

I opened a document, Librera set in landscape mode, but the document opened in double page using a zoom that seems to contain around 1.625 pages (linearly) instead of 2.
It looks like it may have opened with the zoom for "portrait, single page".

In the preferences, "Cover image size" section, it would be nice that:

• the "Grid [size]" and "Column count" do not necessarily modify each other;
• a checkbox "Auto adjust" is used to have current behaviour of relation of "Cover image size in grid" and column count;
• the cover image size still cannot be more than (screen size / column count);
• but if the cover image size is small (e.g. 80), and the columns large (e.g. count = 4), good, the grid shows a small cover, but with large text strings (title, filename etc.), and the grid rows are short proportionally to the cover image size (instead of tall);
• also, a checkbox could "hide the cover": in this case, * the column count determines the column width, * the cover size determines the column height (the same as if the cover was displayed), and * the text screen occupy the space instead of the cover page, and they word wrap.

As the icon for the "fit and centre" operation, more precisely ImageView ID "@+id/moveCenter", I think that glyphicons_114_justify does not suggest the operation immediately.
On the other hand, I think that glyphicons_488_fit_image_to_frame is almost perfect (this already existing icon is very similar to what I was thinking to draw and propose instead of glyphicons_114_justify).

In case a book does not have a cover (the first page of a PDF, etc.), the software creates a cover by placing a default bitmap, colourizing it, and writing the title on it.

Problem: unrelated random-like colours can be confusing. For example, "The big book, Part 1" in dark brown, "The big book, Part 2" in light blue, "Some other book" in blue. This is messy.

Proposal: the colorization of the book cover uses a default colour (a neutral colour like grey),
but (secondary proposal) the user may assign a different colour to a single book cover from an editable palette, to allow for categorization.

Example: all default covers (those which must be built using the default image with the cursive "L") are grey, but the user has set that "The big book, Part 1" and "The big book, Part 2" are colourized using (say) the fifth colour of the covers palette, say light blue, because that colour represents to the user a category for those books.

(Lower priority)

Librera seems nice, but there are some unpleasant advertisement banners in it. They should be removed.

Also, while I am not a lawyer, it does seem to me that the license should be AGPL instead of GPL, since you are using muPDF, which is AGPL-licensed.

Are you planning an fdroid release?

Dear Ivan,
I use and love your product since the dawn of Android, and I have been always recommending it as the foremost.
I am currently using an Onyx Boox Max Carta, 13.3'' ElectroPhoretic display Android 4.0.4 - it is roughly an A4, but 4:3 instead of √2:1.
Devices are starting to appear that have a screen real estate that make you wish to view PDF documents in landscape mode, horizontal scrolling. (I believe that at some point in time you implemented something similar, a "magazine mode"?) You start with page 1 on the left and you scroll towards the right up to the last page.
I downloaded the Lirbi GIT repository to see if I can implement the feature. But of course it is more sensible if I first of all propose it as a feature request. Please let me know what you think; if I manage to obtain good code I will submit it.

Hello, I've a question :
Do you plan to migrate to Android Studio?
Tks .

NOTE: heavily edited, last edits in the night between Sat 2 and Sun 3 Sep.

Browsing the documents, one can currently use a grid view of the books; it is configured through parameters "Cover image size" and "Column count". The text (title, filename etc.) is placed below the book cover image.

Problem: if the cover size is small, the strings below are too short, but if the cover is large, and the text is long, few documents per screen are visible.

Proposal: to have a more compact grid view, which allows to see more books per screen:

• another "view mode" named something like 'Compact' alongside with 'List', 'Grid' and 'Cover' is added to the relevant pop-up menu;
• if the "compact mode" is on, then "Cover image size" is irrelevant: the book cover image is set to dimensions based on 80dip (80x120 ?);
• "Column count" decides the number of columns;
• The text - the filename only - is placed to the right of the book cover image;
• At least the "starred" and "menu" icons are below the filename.

Below is an example, using "Column count" = 4:

The problem:
scroll speed is constant no matter how much text is on the screen. Sometimes paragraphs are short. Sometimes are long. Sometimes there is a large space between paragraphs and sometimes they are cluttered. Sometimes there are images, and finally there is the spacing between pages. This happens within a single text.

Feature request:
It would be great if the auto-scroll speed was proportional to the amount of words (or characters) shown on the screen.
So when there is a lot of text on the screen scroll speed would be proportionally slower, while when there are few words on the screen it would be proportionally faster.

This would really help a lot!

Closing a document in double page view and open another one cause the new document to be opened in single page view but the icon in top bar show the double page.

A lot of web dicts are integrated, but what about to bind a local dict in the app, i think the dict file should be very small.

I know you developed both, and Librera crashes everytime I start it. eBooka is doing very well.
The beta version of Librera I download here can work, but when I auto updated in Google Play, it never works.
What is the probable reason?

When switching from single page to double page mode, - for example - page 20 of 300 becomes page 20 of 150,
but the two "page 20" are not the same book page.
When switching and while at page 20 of 300, the current page should become 10 of 150 - to keep the same book page

I try to read this book
Name of Book: reactive-programming-with-rxjava-tomasz-nurkiewicz.epub
Size: 5.8 MB
Total pages: 1488
But it displays the progressBar and loads for a long time.

Reflow does not work for scanned PDF file.

I missed this everytime I moved the pages by accidental panning, having forgotten to "lock position":
it would be nice to have the option to re-center the pages on the screen.

You could combine this option with the "(zoom) fit to screen" in easy mode; when scrolling pages (advanced mode) the two options of "centering" and "fit to screen" should be separate

Can't search a sentence or paragraph?
Tks.

The colour surrounding the page in night mode is not black, but dark green; on OLED displays, which have the benefit of a "real black" (lights are off), the area around the page is glowing.
It would be useful to be able to change that background colour, or to set it to black (since on OLED displays it means "off").

Thank you!

Hello Ivan Ivanenko,

Can you export file .so to Github or move all source code via Android Studio for easy use and build .so files?
Because most of the Android dev have switched to Android Studio because Eclipse is no longer supported, so it is very difficult for me to use your library for further development and fix bugs.

Thank you for your contribution to the open source community.

When using text to speech feature, there are multiple issues:

1. It does not start from the current displayed page/text/paragraph (except obviously when starting from the beginning of the book)
2. While speaking, it repeats entire page of text (narration doesn't make any sense anymore, it can repeat something that's 10 page earlier, then some part that are "in the future")
3. There is no feedback about where it is. Ideally, it should overlay, invert, put a dot, or some visual clues about what's being pronounced. This way, it's easy to figure out when it's "restarting" from, instead of trying to outpace while reading the text.

I've tried to use both advanced mode and simple mode with the same result.
I'm using the latest beta downloaded today.

I have an ODPS server with HTTP basic authentication that's working fine with FBReader and iReader.
With Librera, there are 2 issues:

1. When I set up the password, it's displayed in clear text in the server's list (not really wanted)
2. The system never succeeding connecting to the server and thus prevent any action, popping up error dialog endlessly, I have to force close it. I've modified my server not to use authentication, and it's not breaking the crazy loop.

Thanks for support

Guys you are doing greate job and i was actually for some good project like other then fbreader which is not update from long time (one that is open sourced). So just had look on to librera project and as i far as i can see it is continually being developed with interesting features. So have couple questions.

I want to use librera in my open source project as it is under gpl 3.
So, if yes then is Android studio supported for the project or if not
Then is there any better readme/Documentation Available.

Response from your end would be appreciated.

And thanks for such a great contribution to the community.

I am seeing, discussing in forums, that many users on mobile devices are missing simultaneous browsing of many documents, which they would do on desktops (multi-window or multi-tabs).
It is like multi-tab browsing on Web browsers.
Do you think it can be done?

(Apologies for any delay, I am currently away)
