          ebook-polish [options] input_file [output_file]

       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 alebo 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"

[MOŽNOSTI]

       --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
              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
              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.

       --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 don't 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
              Podmnožina  písma znamená zredukovanie vloženého písma iba na znaky z tohto písma použité v knihe.
              Toto výrazne znižuje veľkosť  súborov  písma  (polovičné  písmo  veľkosť  súborov  je  bežná).  Ak
              napríklad  kniha  používa konkrétne písmo pre hlavičky, potom podsúbor zredukuje písmo, ktoré bude
              obsahovať len znaky prítomné v aktuálnych hlavičkách  knihy.  Alebo  ak  kniha  obsahuje  tučné  a
              kurzíva verzie písma, ale tučné a text kurzívou sú relatívne vzácne, alebo úplne chýba potom tučné
              a  kurzívne písma môžu byť zredukované iba na pár znakov alebo úplne odstránené. Jedinou nevýhodou
              pre podsúbor písma je, že ak sa neskôr rozhodnete pridať ďalší text do vašich kníh,  novo  pridaný
              text nemusí byť pokrytý podmnožinou písma.

       --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.

       --version
              zobraziť verziu programu a skončiť
