       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 vagy 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"

[BEÁLLÍTÁSOK]

       --add-soft-hyphens, -H
              Add soft hyphens to all words in the book. This allows the book to be  rendered  better  when  the
              text is justified, in readers that do not support hyphenation.

       --compress-images, -i
              A   könyvben  lévő  képek  veszteségmentes  tömörítése,  csökkentve  a  fájlméretet  a  képminőség
              befolyásolása nélkül.

       --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
              Embed  all  fonts that are referenced in the document and are not already embedded. This will scan
              your computer for the fonts, and if they are found, they  will  be  embedded  into  the  document.
              Please ensure that you have the proper license for embedding the fonts used in this document.

       --help, -h

       --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
              Path to an OPF file. The metadata in the book is updated from the OPF file.

       --remove-jacket
              Remove a previous inserted book jacket page.

       --remove-soft-hyphens
              Remove soft hyphens from all text in the book.

       --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
              Subsetting fonts means reducing an embedded font to contain only the  characters  used  from  that
              font  in the book. This greatly reduces the size of the font files (halving the font file sizes is
              common). For example, if the book uses a specific font for headers, then  subsetting  will  reduce
              that font to contain only the characters present in the actual headers in the book. Or if the book
              embeds  the  bold  and  italic versions of a font, but bold and italic text is relatively rare, or
              absent altogether, then the bold and italic fonts can either be reduced to only a  few  characters
              or  completely  removed.  The  only  downside  to subsetting fonts is that if, at a later date you
              decide to add more text to your books, the newly added text might not be  covered  by  the  subset
              font.

       --upgrade-book, -U
              Upgrade  the  internal structures of the book, if possible. For instance, upgrades EPUB 2 books to
              EPUB 3 books.

       --verbose
              Produce more verbose output, useful for debugging.
