Solve the issue when a font without bold and italic variants
is used as the default font (e.g. FreeSerif), and the style
tweak "Ignore publisher font-family" is used (which uses
a trick to cancel any font-family by requesting a font
named "NoSuchFont"):
When text is italic or bold, any of the registered fonts
which have a real italic or bold variant would win over our
default font, as the best substitute to NoSuchFont-Italic.
This gives our default font a bit more bias so it can
win in its scoring against the other fonts, and be rendered
as fake italic or fake bold - which will ensure consistent
font and line height.
(A bit hacky, but no alternative solution found.)
Enable new rendering feature COMPLETE_INCOMPLETE_TABLES
on all enhanced rendering mode, but have it disabled for
earlier cre_dom_version.
Also increase default_cre_storage_size_factor from 20 to 40.
* Allow running Shell/Python scripts from the FM
* Show an InfoMessage before/after running the script
Since we're blocking the UI ;).
* Allow running scripts from the favorites menu, too.
Also reset cache when calling :enableInternalHistory(), as it solves
screen orientation change unit tests failures (although there is no
issue in regular use of the app).
Optimise usage of some of CreDocument methods by caching
their results, either globally, or per page/pos for those
whose result may depend on current page number or y-pos.
This helps a lot on cre books with a lot of highlights.
Includes:
- New option to tune word spacing: space width scale percent
- Text: look for hyphenation in more words if needed
- CSS: fix "hyphens:none" should override inherited "hyphens:auto"
- getHtml(): grab dir= and lang= attributes from upper nodes
Replace our Word Gap/Space condensing toggle/setting with
a new Word Spacing toggle/setting, made of 2 values:
- 1st number scales the normal width of spaces in all font
(100% uses the font space width untouched)
- 2nd number applies after the 1st has been applied, and
tells how much these spaces can additionally be condensed
to make more text fit on a line.
Includes:
- (Upstream) Unified cache for chars and glyph's indexes
- (Upstream) Glyph caching: optional use of hash table instead of a linked list
- (Upstream) Adds docx and fb3 support
- Update hardcoded elements list and stylesheets
- DocX: build a HTML DOM instead of a FB2 DOM
- Text: allow wrap after '/' and '-'
- Text: with Harfbuzz, split measurement on text node change
- Clear fonts on load and re-rendering
Includes:
- Adds tinyNodeCollection::getStatistics()
- epubfmt.cpp: cleanup indentation and small optimisation
- Add more progress callback events
- Optimisation: avoid re-init for EPUBs with embedded fonts
- Fix: don't draw border when border-color: transparent
- CSS: ignore 'inherit' inside font-family
Show a small progress meter at top left of screen when
crengine is loading, re-rendering, and saving cache file
(after a 2 second delay to not be bothered on small books).
Also add a wrapper for the last remaining bit of code that
was accessing _document directly (:getPageOffsetX()).
This commit standardizes the various todos around the code a bit in a manner recognized by LDoc.
Besides drawing more attention by being displayed in the developer docs, they're also extractable with LDoc on the command line:
```sh
ldoc --tags todo,fixme *.lua
```
However, whether that particular usage offers any advantage over other search tools is questionable at best.
* and some random beautification
Bump crengine: background image and other fixes:
- View HTML: option to show text unicode codepoints
- Fix attribute parsing: decode &-encoded chars
- Text: allow wrap after more unicode spaces and hyphen
- Fix: no left hanging when hanging punctuation disabled
- lvtextfm.cpp: more comments, some formatting cleanup
- Optimize background image drawing
- CSS: fix background-image file path resolution
Bump luasec to 0.8.1
Bump harfbuzz to 2.6.0
cre.cpp:
Adds setBackgroundImage() proxy function to crengine
facility to set background textures (this is unrelated
to the background-image CSS fixes).
No frontend code (yet) to select such an image.
View HTML: adds a 3rd view (extended debug view), showing the
unicode codepoint of each char and crengine rendereing methods.
Adds "Render mode" toggle with 4 modes, to enable some or all
of crengine's new enhanced block rendering features.
Use "legacy" rendering for previously opened books to not mess
with bookmarks, and "web" (all of the new features) for new books.
Also make available the added "HTML5" stylesheet to the Style menu.
- Removed "Swipe to follow first link on page" menu item and
handling code, as it feels not really as practical as
"Swipe to follow nearest link".
- Removed recently added "External link action", as we can
just always present a popup with the url and the available
actions.
- Generic handling of these actions in onGoToExternalLink(),
so they are proposed on the Wikipedia lookup popup too.
- Allow external link on PDF documents (previously, only
internal links were handled).
- Have "Ignore external links on tap" available on all
document types.
- Added "Ignore external links on swipe" (default to true,
the current behaviour).
- Added multiswipe gesture "Follow nearest internal link"
(the existing "Follow nearest link" now follows the
nearest external or internal link)
- ButtonDialogTitle: added an option to look a bit more
alike ConfirmBoxes.
- Footnote popups: fix link unhighlight when tap on external link.
Have the code pre-invert some images when in night mode,
so they get inverted back to normal by night mode.
This will allow images to be displayed normally in
the following contexts:
- images in credocument pages
- long-press on images in credocument viewed in ImageViewer
- cover thumbnails in File browser and History
- full size covers when viewed in ImageViewer
- images in Wikipedia lookup results
It was doing a full document load to get the cover. It now does
the faster "only metadata" load.
Also move the trick of setting a default font in CreDocument, so
that all callers of document:loadDocument(false) benefit from it.
Prevent crash when no cover image is available (even if the cache
says it has one, the file may have been updated and doesn't have
it anymore).
Similar to what's been added for 1 page view, but just turn
one page instead of switching to scroll mode when reaching
top left or bottom right corners.
Also make the selection start xpointer more accurate by
getting them in onHold(), instead of possibly too late in
onHoldPan() where we have already moved.
Adds a toggle switch in the Orientation bottom config menu to
allow showing 1 page or 2 pages when in landscape mode.
Previously, this was hardcoded to be in 2-pages modes only
in some circumstances (device resolution + user dpi).
By scrolling last page a little bit further.
Also fix a few other scroll mode issues, all related
to doc_height not being updated (eg, in the middle of
a book, and doubling the font size, one would not
be able to turn pages and read the 2nd half of the
book...)
Avoids a use-after-free in mupdf.scaleBlitBuffer
Fixkoreader/koreader-base#821
Thanks for the hint, @poire-z ;).
* As @poire-z suggested, the original unscaled bb should probably be free'd.
Includes:
- Update french hyphenation pattern
- epub.css: update style for 'blockquote'
- DrawBuf: count nb of images and surface drawn
Adds Document:getDrawnImagesStatistics() to help deciding
if refresh with (possibly costly) dithering should be used
(on devices with HW dithering capabilities) with CreDocument:
when a page contains enough images to benefit from it.
