Setting the hyph algo before loading the document may save crengine
from re-doing some expensive work at render time (the hyph algo
is accounted in the nodeStyleHash, and would cause a mismatch if it is
different at render time from how it was at load time - "English US" by
default - causing a full re-init of the nodes styles.)
We will only re-set it on pre-render (only then, after loading, we
know the document language) if it's really needed: when no algo saved
in book settings, no default algo, and book has some language defined.
* Better KOA2 support
* Fix FL
* Add physical pageturn keys
* Add accelerometer support
* Possibly better NaturalLight handling on the Clara
* Fix WiFi module name used in some(?) Mk7 Kobos
* A bunch of kodev fixes
Adds a new Hyphenation method: Soft-hyphens only.
Adds a new toggable option, usable with Algorithm and language
based methods: Trust soft hyphens (if enabled, if soft hyphens
found in word: use them and skip regular method).
Default in crengine is 50%, and this may be too much for some
people (words can look too much stuck to each other on some lines).
This manual setting may help testing if 70% or 80% is better, with:
"cre_min_space_condensing_percent" = 80
Includes:
- Avoid page break between a node and its borders
- Allow building an alternative TOC from document headings
On CRE documents, allows toggling between original TOC and an
alternative TOC with long-press on the "Table of content" menu
item.
Also update the Wikipedia stylesheet to further avoid
page-breaks between images and their caption, so a full
bordered wikipedia thumbnail is always full on a single page.
Use epub.css as the main default style, with all file formats
except FB2 (which needs fb2.css).
(epub.css has been cleaned recently to be more conforming to HTML
specs and to not include class name based styles - with conditional
compatiblity styles for previously opened documents. It should be
usable on all HTML based documents, except FB2 which has some
incompatible specs.)
Consider all shipped css files other than "epub.css" and "fb2.css"
obsolete, and put them in a sub-menu (these other css files have
not been updated in the same way, and are kept as-is for when a
previously opened document requests one of them).
Add an icon indicating which style is set as default (like it's
been done for the Font and Style tweaks menus).
Also set the font size of the full status bar (available with
cre documents) when the setting "cre_header_status_font_size"
is present in settings.reader.lua (to add manually).
* Switch all initial highlights to "fast" update
i.e., everything that does an invert
Plus a few other things that refresh small UI elements onTap
Re #3130
* Tweak refreshtype for a number of widgets:
* Fix iconbutton dimen
* Make touchmenu flash on close & initial menu popup. Full-screen on close.
* Use flashing updates when opening/closing dictionary popup. Full-screen on close.
* Switch FileManager to partial.
It's mostly text, and we want flash promotion there.
* Make configdialog & menu flash on exit
* Make FLWidget flash on close
* virtualkeyboard: flash on layout change & popup.
* Potentially not that great workaround to ensure we actually see the
highlights in the FM's chevrons
* Flash when closing BookStatus Widget
* Optimize away a quirk of the dual "fast" update in touchmenu
* Promote updates to flashing slightly more agressively.
* Document what each refreshtype actually does.
With a few guidelines on their optimal usecases.
* Switch remaining scheduleIn(0.0) to nextTick()
* Tighter scheduling timers
Shaving a hundred ms off UI callbacks...
* Cache FFI C Library namespace
* Ask MuPDF to convert pixmaps to BGR on Kobo
Fix#3949
* Mention koxtoolchain in the README
re #3972
* Kindle: Handle *all* fonts via EXT_FONT_DIR instead of bind mounts insanity
* Make black flashes in UI elements user-configurable
(All or nothing).
* Jot down some random KOA2 sysfs path
Books previously opened (that have a metadata.lua, whether with
highlights or not, but because they all have a last_xpointer that
points to the current page, that can be broken too by the changes)
will continue to have the old wrong behaviour, so they won't be
impacted by the breaking changes.
Update cre_dom_version code to use the new functions from cre.cpp.
Remove these Workarounds from Style tweaks.
Alternate rendering of list items as block elements (instead of
inline/final).
Check the built DOM is still coherent with styles on stylesheet
change, and propose to reload the document if not. Also
invalidate cache on close in that case so a new DOM is built
at next opening.
ReaderStyleTweak: fix tweak css duplication; when globally
enabled, when disabling and re-enabling locally, the css would
be added twice to the final CSS.
Also adds !important to "sub_sup_smaller" tweak, and increase
its priority so it can override "font_size_all_inherit".
Adds CreDocument:getCacheFilePath() for futur features.
Also allows for updating the fallback font and see results
in real-time on the underlying document.
Bump crengine for: fix updating fallback font
Also adds a menu item to generate a html document showing some
sample text rendered with each available font (only if the user has
a file koreader/settings/fonts-test-sample.html with some HTML
snippet of his choice).
Includes:
- [build] FreeType: bump to 2.9.1
- [build] bump libjpeg-turbo to 1.5.3
- bump crengine:
- Fix CSS selector specificity computation
- [fix] crengine/src/lvfntman.cpp: improve letter_spacing limit
- [fix] crengine/src/lvxml.cpp: add all empty HTML elements
- html head styles: fix styles not being applied
- Hyphenation: increase MAX_PATTERN_SIZE from 16 to 35
- html documents: proper handling of <BR> tags
- Allows requesting old (broken) XML/DOM building code
- cre.cpp: setStyleSheet(): accept filepath and/or css text,
and added getIntProperty() and getStringProperty()
credocument/readerrolling: request older XML/DOM building code
for books previously opened, to not lose bookmarks and highlights
(unit tests update because of new handling of consecutive BR via css
pushed links down in the book)
New module RenderImage (alongside existing RenderText) to provides
image rendering and scaling facilities.
Uses MuPDF, but tries first giflib on GIF.
Allows for getting all the frames from an animated GIF.
When hyphenating a word, the existing algorithms enforced a minimal
length of 2 for each word fragments on left or right side.
This adds a widget to allow changing these minimal sizes (from 1 to 10).
bump crengine:
Allow for quicker loading when interested in metadata only.
Allow for more than 65535 different attribute values.
Increase gamma values range.
Bump crengine for cache re-use fix and warnings when
cache sizes reached.
Allow for increasing some crengine cache sizes with a new
setting: "cre_storage_size_factor" = 1.5 (or 2, or 4...)
With ["cre_compress_cached_data"] = false in settings.reader.lua.
Not using compression for cache files does indeed take more space,
but it does speed up opening, rendering, page turns, and closing,
with big documents.
Bump base and crengine.
cre:loadDocument() may fail in recognizing the document format, and
koreader would previously keep calling other methods on it, which would
make crengine segfaults. We now check loadDocument success at the
various places it is called, and try to deal the best way we can when it fails.
This is done by/for kosync plugin at each opening, because
the docsettings was re-opened and saved for this, but later
overwritten by the current koreader docsettings - so it was
redone each time. This correctly adds this partial_md5_checksum
to the current koreader docsettings, which will be saved on
document closing - so it will not be redone next time.
Note: this partial_md5_checksum is not (yet) used by anything.
Avoid unnecessary work in ReaderView:onSetViewMode() and
ReaderRolling:updatePos() that would result in TOC being reset
and rebuilt (which can take time on books with huge TOC) during
reader setup.
* Allow for colored rendering
Available with all engines (CRE, PDF, Images).
Needs to manually add setting: "color_rendering" = true
* Disable color for djvudocument
* Use Screen:isColorEnabled()
* Bump base
Base bumped.
Previsouly, parts of document in <p style="font-family: serif">
would be rendered with the first font set, and would not
follow change of font (unline other texts without styles).
That was observable with Embedded Styles set to On, but is even
more noticiable with the new Embedded Fonts setting set to off.
Just under the existing "Embedded Styles". Support for this
was already there in crengine, and interfacing is similar to
what is done with Embedded Styles.
So an image file can have a cover in coverbrowser's display.
It also allows for an alternative viewer (ImageViewer widget)
when holding on file / View full size cover.
They may already be available (with other statistics stuff) under
the 'stats' key, but not if Statistics plugin is disabled. As this
plugin may be migrated to SQLite, readerui and readerfooter will now
set two new properties: doc_props (containing all and only the metadata
returned by document:getDocumentProps()) and doc_pages (updated
by readerfooter on any display or font change).
PDF document: returns additional PDF properties: Keywords
and Subject (as Description).
CRE cache, hyphdict and fonts can be initialized only once
when first credocument is opened. Previously, they were
recreated for each document, and as previous instances were probably
not free'd, this caused memory leaks.
When such blank page has only a few black pixels (dust), it would result in
a really small cropped area, than when scaled to fit screen, would cause a
crash with :
./ffi/mupdf.lua:63: could not allocate pixmap:
malloc of array (451342 x 612558 bytes) failed (integer overflow) (1)
Fix similar to what is done in KoptInterface:getAutoBBox(): when cropped area too small,
fall back to whole page (or here: to user's manually set area).

this should implement feature request of zoom mode for multi-columns
page in #501
This PR depends on koreader/koreader-base#435
How to use?
1. Tap the top left corner of a PDF/Djvu page to get into the flipping
mode
2. Double-tap on text block will zoom in to that column
3. Double-tap on any area will zoom out to an overview of the page
4. repeat step 2 to focus to another page block
How does it work?
1. We first find the mask of text blocks in the page. (Pic 1)
2. Then we intersect page boxes with user tap to form a page block. (Pic 2)
3. Finally we zoom the page to the page block and center current view to
that block. (Pic 3)
Currently only tested on Ubuntu-touch emulator with framework
ubuntu-sdk-14.10 for armhf.
The ubuntu-touch port is binary compatible with the Kobo port
major changes in this PR are:
1. rename the emulator device to sdl device since both the emulator
and the ubuntu-touch target use libsdl to handle input/output.
2. ubuntu-touch app has no write access to the installation dir so
all write-outs should be in a seperate dir definded in `datastorage`.
On kindle, kobo and pocketbook the data directory is the current
running directory but on Android the app is installed in system
defined location and users may have no access to that location.
The same circumstances should be true for the upcoming Koreader for
Ubuntu touch, so the data directory (in which tessdata, dictionaries,
global settings, persistant defaults and probably history data are
stored) could be stored in another place.
to support custom font directory for EPUB documents
Now Koreader could find fonts in the "fonts" directory in the USB root
directory of kindle, Kobo and PocketBook devices, thus no need to copy
fonts to "koreader/fonts" directory.
This is a major overhaul of the hardware abstraction layer.
A few notes:
General platform distinction happens in
frontend/device.lua
which will delegate everything else to
frontend/device/<platform_name>/device.lua
which should extend
frontend/device/generic/device.lua
Screen handling is implemented in
frontend/device/screen.lua
which includes the *functionality* to support device specifics.
Actually setting up the device specific functionality, however,
is done in the device specific setup code in the relevant
device.lua file.
The same goes for input handling.
so that when document is modified the persistent cache will
be invalidated automatically because the cache key will not
be matched. There is no perfermance overhead here at all. We
even don't need to check the modification time of the cache item
on disk, because the name of the on disk cache is a md5sum of the
cacheitem key, now the filename of the cache files contains the
modification time information.
If the document is modified since one rendered page is cached to disk,
the cache key won't match the cache file. And the cache file will
be discarded without the need to open the cache file or to check
the modification time of the cache file itself.
This will use the new API where the Lua/C interface was used before
and also drop usage of mupdfimg wrapper which is now implemented
within the mupdf interface
so that when calling getCoverPageImage in screensaver mode
the document won't be opened again. This should avoid a lot of
problem such as messing up style and options described in #863.
We may have multiple documents opened simultaneously, such as in
screensaver mode the current document is opened twice, it's better
to keep seperate info table for each document.
This should fix#858. When a credocument is opened for screensaver to
get the cover page, the total pages info is set to 1(strangely enough),
before this fix this total pages is shared with the reading document
so the progress bar will get a progress percentage well beyond 100% and
rendering the progress bar out of the boundering box as shown in #858.
