* 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
* 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
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).
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)
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
In regional zoom mode double tap will zoom to the tapped
region(paragraph or column, etc., detected optically via libk2pdfopt).
As the first demo, this feature is only turned on in flipping mode by
tapping the top-left corner of the screen. Eventually we may incorporate
this feature in "free" zoom mode.
and there is no need to OCR word if we can extract text from
original page in reflowing mode thanks to the rect maps between
normal page and reflowed page.
