Thorium Reader|多格式电子书阅读器安装版 v3.2.1

Thorium Reader 是一款开源免费、扩平台、无广告的电子阅读器，虽然官方宣称Thorium Reader是 Windows 10 和 11、MacOS 和 Linux 的首选 EPUB 阅读器，但它不是只支持epub格式的阅读器，它还支持pdf、opf、webpub等格式。从目录或 OPDS 导入电子书后，你将能够在任何屏幕尺寸上阅读，自定义布局设置，通过目录或页面列表导航，设置书签… 我们非常注意确保使用 NVDA、JAWS 或 Narrator 的视障人士能够使用该应用程序。

用户友好的界面
该应用程序允许你添加你有兴趣阅读的电子书。随着时间的推移，你以前加载的所有文件都会在主窗口内出现，所以你可以轻松地继续阅读，而不需要再次找到电子书文件。

此外，需要提及的是，无论你的电子书是哪种格式，你只需点击一下鼠标就可以将其导出为EPUB。这样，你可以用你可能需要的任何电子书阅读软件解决方案打开它。

不用分心的电子书阅读器
在你选择了你想阅读的电子书后，你可以浏览其内容并跳转到你喜欢的章节。你还可以添加书签，这样你就可以在以后的时间里轻松找到它们。

此外，还有大量的设置，你可以自定义，使整个阅读体验尽可能的愉快。你可以修改主题、字体类型和大小，以及间距。

你还可以改变布局和对齐方式–如果你选择分页布局而不是可滚动的布局，你可以选择1列或2列。

内置 TTS 引擎
Thorium Reader 的一个很大的特点是，它带有一个集成的文本到语音模块，允许你听你的电子书，而不是阅读它。你可以启用字幕，以帮助你在阅读过程中跟踪文本的进展。

版本日志

Thorium is now based on Electron v37 (and its updated Chromium version). Version 37 introduced a regression bug with audio/video streaming (time seeking) but this was fixed in time for this Thorium release.
Localisation: added and updated translations, fixed Chinese handling (was incorrectly triggering RTL)
PDF: new print feature, updated PDF.js rendering library
Annotations/bookmarks: exports raw data (JSON format, W3C standard) as well as HTML template. Export is possible outside of a reader window (from the library / local bookshelf)
Annotation highlights: support for EPUB CFI in data import/export (Colibrio open-source lib)
Annotations/bookmarks: added a warning message when a publication that contains bookmarks/annotations is about to be removed (suggestion to export the notes)
Annotations/bookmarks: harmonized models, editor GUI for textual notes, tag, etc.,
Annotations/bookmarks: support for emojis via GitHub-flavoured Markdown
Annotations/bookmarks: rendering engine displays floating popup with text excerpt on mouse hover
Annotation highlights: now with named colours as opposed to just arbitrary RGB triplets
Bookmarks: new visual indicator in document margins
Bookmarks: fine-grain "current reading location" detection (mouse click) for precise character-level bookmarking (still default to implicit leading text position in visible text)
Annotations: when highlights are hidden (not even in margin), and the user selects text + creates annotation, nothing was displayed which was causing confusion and multiple user attempts to create (duplicates). This forces the display of annotations when the user creates.
GUI: improved the horizontal publication strips in the library window, now scrolls natively and snaps to publication covers boundaries (panning works with mouse wheel, touch swipe, arrow keys etc.)
TTS: new highlight styles configuration GUI
TTS readaloud fixes: on last spine item natural play ending (publication finish), turn off TTS "play on click" behaviour, also: hide annotations while playing, restore after stop. Also fixed race condition during play, click, auto forward progression, switch document backwards/forwards, and natural document/publication end (handles annotations hide/restore, continues to ignore hyperlink clicks during active readaloud, until stopped by user or automatically by TTS engine)
TTS: fixed potential crash in Linux when selecting synthetic speech voices
TTS: horizontally-centered TTS utterance with minimal jittering in scrolling mode
TTS: improved readaloud mouse tracking with paragraph spanning across page boundary
TTS: fixed pause/stop event which was causing GUI flicker
TTS: voice selection supports multiple per-language user preferences
Keyboard shortcuts: list / editor now with search filtering by keyword, duplicate detection, and localized labels.
Keyboard shortcuts: user overrides now persist correctly in json partial data structure on filesystem (was incorrecty serialising all shortcuts including defaults).
Keyboard shortcuts: display correct characters for non-QWERTY keyboard
Navigation: fixed hyperlinking into search results which wasn't inserting history events for go back/forward
Navigation: fixed popup footnotes back/forward hyperlinking history
OPDS: fixed the OAuth flow which needed to be restarted when a refresh token was revoked or invalid
Accessibility: updated support for the display guide specification
LCP: improved LSD network timeout, added async loading spinner (GUI)
DAISY import: fixed virtual zip archive handling of subfolders (DAISY2.02 NCC.html non-zipped publication folder, for example)
EPUB3 Media Overlays: fixed playback of precorded audio clips with implicit natural stream ending, also fixed edge case of HTML documents that start with markup that doesn't participate in SMIL synchronization (seek ahead algorithm)
EPUB3 Media Overlays: added GUI control checkbox for "ignore MO and read with TTS instead"
EPUB3 Media Overlays (and DAISY2.02 DAISY3.0): improved synchronised text-audio talking books, which now fallback on TTS when pre-recorded audio clips are not present in SMIL par pairs (only text reference). Can be full SMIL-TTS book, or partial interspersed / mixed TTS / audio-clips.
GUI: fixed the bottom progression bar which was not capable of handling great numbers of spine items, now minimum mouse cursor hit size (width) required
Accessibility: fixed keyboard focus handling inside HTML documents, screen reader detection to avoid interfering during scroll repositioning, also avoiding element focus during selection change.
Screen reader fix: left/right arrow hot key binding to "page turn" interferes potentially with current reading location during screen reader usage
Accessibility fix: "skip link" in reader window is equivalent to FocusMainDeep CTRL F10 with SHIFT
Fixed TTS Japanese Ruby handling, baseline text DOMRange-rendered but not spoken, unless Ruby is hidden/disabled. Also increased underline gap hoping to eliminate rendering artefacts in Windows
Fix: DAISY3 DTBOOK parser was choking on 60,000 lines / 8MB frontmatter
LCP fix: PDF import workaround for servers that respond with HTTP header content-disposition for PDF filename instead of LCPDF
Fixed Windows publication export filename which cannot contain ":" colon
Added support for PNLD EPUB extension (in addition to .epub and .epub3)
Accessibility fix: automatically disable pagination (CSS columns in reflowable documents) when screen reader is detected
Fixed AccessibleDfA typeface (dyslexic)
Adopted ReadiumCSS font-size / zoom fix
Image zoom/pan GUI now implemented in Thorium via localizable React GUI
Fixed Arabic and other Right To Left metadata accessibility summary and author/publisher/contributor in publication info dialog
Fixed zoom in pre-paginated / fixed-layout EPUB, and keyboard shortcuts for zoom in/out/reset which were not working in "zen mode"
Fixed HTTP header content-disposition filename handling (sanitization for cross-platform Windows, Linux, Mac filesystems)
