       Polishing  books  is all about putting the shine of perfection onto your carefully crafted
       e-books.

       Polishing tries to minimize the changes to the  internal  code  of  your  e-book.   Unlike
       conversion, it does not flatten CSS, rename files, change font sizes, adjust margins, etc.
       Every action performs only the minimum set of changes needed for the desired effect.

       You should use this tool as the last step in your e-book creation process.

       Note that polishing only works on files in the AZW3 或 EPUB formats.

       Whenever you pass arguments  to  ebook-polish  that  have  spaces  in  them,  enclose  the
       arguments in quotation marks. For example: "/some path/with spaces"

[選項]

       --compress-images, -i
              Losslessly  compress  images in the book, to reduce the filesize, without affecting
              image quality.

       --cover, -c
              Path to a cover image. Changes the cover specified in the e-book. If  no  cover  is
              present, or the cover is not properly identified, inserts a new cover.

       --embed-fonts, -e
              文檔中尚未嵌入所有引用的字體。此操作將會掃描您電腦中的字體， 如果找到這些字體，將嵌
              入這些字體到文檔中。 請確保您有足夠的權限來使用內嵌字體的文檔。

       --help, -h
              顯示此幫助信息並退出

       --jacket, -j
              Insert a "book jacket" page at the start of the book that  contains  all  the  book
              metadata  such  as  title,  tags, authors, series, comments, etc. Any previous book
              jacket will be replaced.

       --opf, -o
              OPF 檔案路徑。書籍中的詮釋資料是從 OPF 檔案更新。

       --remove-jacket
              移除先前插入的書籍封面頁。

       --remove-unused-css, -u
              Remove all unused CSS rules from stylesheets and <style> tags. Some  books  created
              from  production  templates  can  have  a large number of extra CSS rules that dont
              match any actual content. These extra rules can slow  down  readers  that  need  to
              parse them all.

       --smarten-punctuation, -p
              Convert  plain  text  dashes,  ellipsis,  quotes, multiple hyphens, etc. into their
              typographically correct equivalents. Note that the algorithm can sometimes generate
              incorrect  results,  especially when single quotes at the start of contractions are
              involved.

       --subset-fonts, -f
              嵌入子集字體意味著可以減少內嵌字體的體積大小，因爲只 使用書籍中所需要調用的字元。這
              有助於大幅減少字體文件的大  小（通常能減少近一半的體積）。 舉個例子，如果一本書爲標
              題使用了特定的字體，子集字體 將只保留使用標題字元中使用的字體。或者是如果書籍內嵌了
              字  體的粗體和斜體，但是卻很少使用粗體和斜體，那麼粗體和斜體 可能會被精簡爲少量的字
              元，甚至是完全被移除。 子集字體唯一的缺點是，如果您想在以後爲您的書籍添加更  多的內
              容，新的內容可能無法使用原有的子集字體。

       --verbose
              產生更詳細的輸出，以利除錯。

       --version
              顯示程序版本號並退出
