ebook-convert - ebook-convert
ebook-convert input_file output_file [options]
Convert an e-book from one format to another.
input_file is the input and output_file is the output. Both must be specified as the first
two arguments to the command.
The output e-book format is guessed from the file extension of output_file. output_file
can also be of the special format .EXT where EXT is the output file extension. In this
case, the name of the output file is derived from the name of the input file. Note that
the filenames must not start with a hyphen. Finally, if output_file has no extension, then
it is treated as a folder and an "open e-book" (OEB) consisting of HTML files is written
to that folder. These files are the files that would normally have been passed to the
output plugin.
After specifying the input and output file you can customize the conversion by specifying
various options. The available options depend on the input and output file types. To get
help on them specify the input and output file and then use the -h option.
For full documentation of the conversion system see conversion
Whenever you pass arguments to ebook-convert that have spaces in them, enclose the
arguments in quotation marks. For example: "/some path/with spaces"
The options and default values for the options change depending on both the input and
output formats, so you should always check with:
ebook-convert myfile.input_format myfile.output_format -h
Below are the options that are common to all conversion, followed by the options specific
to every input and output format.

TUỲ CHỌN NHẬP
Các tuỳ chọn điều chỉnh xử lý của tập tin nhập mobi
--input-encoding
Xác định bảng mã của tập tin được nhập vào. Nếu được thiết lập, tuỳ chọn này sẽ ghi
đè mọi bảng mã được khai trong chính tập tin đó. Thích hợp cho các tập tin không
nêu rõ bảng mã hoặc gặp lỗi trong quá trình xác định bảng mã.
TUỲ CHỌN XUẤT
Các tuỳ chọn điều chỉnh xử lý của tập tin xuất epub
--dont-split-on-page-breaks
Turn off splitting at page breaks. Normally, input files are automatically split at
every page break into two files. This gives an output e-book that can be parsed
faster and with less resources. However, splitting is slow and if your source file
contains a very large number of page breaks, you should turn off splitting on page
breaks.
--epub-flatten
This option is needed only if you intend to use the EPUB with FBReaderJ. It will
flatten the file system inside the EPUB, putting all files into the top level.
--epub-inline-toc
Insert an inline Table of Contents that will appear as part of the main book
content.
--epub-toc-at-end
Put the inserted inline Table of Contents at the end of the book instead of the
start.
--epub-version
The version of the EPUB file to generate. EPUB 2 is the most widely compatible,
only use EPUB 3 if you know you actually need it.
--extract-to
Extract the contents of the generated EPUB file to the specified folder. The
contents of the folder are first deleted, so be careful.
--flow-size
Split all HTML files larger than this size (in KB). This is necessary as most EPUB
readers cannot handle large file sizes. The default of 260KB is the size required
for Adobe Digital Editions. Set to 0 to disable size based splitting.
--no-default-epub-cover
Thông thường, nếu các tập tin nguồn không có bìa sách và bạn không chỉ định trước,
một bìa mặc định được tạo ra với tiêu đề, tác giả,...Chọn để vô hiệu hóa chức năng
này.
--no-svg-cover
Không sử dụng SVG cho bìa sách. Chọn nếu EPUB của bạn sẽ được sử dụng trên một
thiết bị không hỗ trợ SVG, như iPhone hay JetBook Lite. Nếu không chọn, những thiết
bị trên sẽ hiển thị bìa như là một trang trắng.
--preserve-cover-aspect-ratio
When using an SVG cover, this option will cause the cover to scale to cover the
available screen area, but still preserve its aspect ratio (ratio of width to
height). That means there may be white borders at the sides or top and bottom of
the image, but the image will never be distorted. Without this option the image may
be slightly distorted, but there will be no borders.
--pretty-print
Nếu được thiết lập, plugin xuất dữ liệu sẽ tạo tập tin xuất dễ đọc nhất có thể. Có
thể không có hiệu lực với một số plugin xuất dữ liệu.
--toc-title
Title for any generated in-line table of contents.
LOOK AND FEEL
Các tuỳ chọn điều chỉnh theo trải nghiệm cho tập tin xuất
--asciiize
Transliterate Unicode characters to an ASCII representation. Use with care because
this will replace Unicode characters with ASCII. For instance it will replace
"Pelé" with "Pele". Also, note that in cases where there are multiple
representations of a character (characters shared by Chinese and Japanese for
instance) the representation based on the current calibre interface language will
be used.
--base-font-size
The base font size in pts. All font sizes in the produced book will be rescaled
based on this size. By choosing a larger size you can make the fonts in the output
bigger and vice versa. By default, when the value is zero, the base font size is
chosen based on the output profile you chose.
--change-justification
Thay đổi cách canh lề chữ. Giá trị "left": canh lề trái. Giá trị "justify": canh
đều. Giá trị "original" (mặc định) giữ nguyên lề tài liệu trong tập tin đầu vào.
Chú ý: Chức năng canh lề chỉ có trong một vài định dạng xuất.
--disable-font-rescaling
Không tự đổi cỡ font
--embed-all-fonts
Embed every font that is referenced in the input document but not already embedded.
This will search your system for the fonts, and if found, they will be embedded.
Embedding will only work if the format you are converting to supports embedded
fonts, such as EPUB, AZW3, DOCX or PDF. Please ensure that you have the proper
license for embedding the fonts used in this document.
--embed-font-family
Embed the specified font family into the book. This specifies the "base" font used
for the book. If the input document specifies its own fonts, they may override this
base font. You can use the filter style information option to remove fonts from the
input document. Note that font embedding only works with some output formats,
principally EPUB, AZW3 and DOCX.
--expand-css
By default, calibre will use the shorthand form for various CSS properties such as
margin, padding, border, etc. This option will cause it to use the full expanded
form instead. Note that CSS is always expanded when generating EPUB files with the
output profile set to one of the Nook profiles as the Nook cannot handle shorthand
CSS.
--extra-css
Either the path to a CSS stylesheet or raw CSS. This CSS will be appended to the
style rules from the source file, so it can be used to override those rules.
--filter-css
A comma separated list of CSS properties that will be removed from all CSS style
rules. This is useful if the presence of some style information prevents it from
being overridden on your device. For example:
font-family,color,margin-left,margin-right
--font-size-mapping
Mapping from CSS font names to font sizes in pts. An example setting is
12,12,14,16,18,20,22,24. These are the mappings for the sizes xx-small to xx-large,
with the final size being for huge fonts. The font rescaling algorithm uses these
sizes to intelligently rescale fonts. The default is to use a mapping based on the
output profile you chose.
--insert-blank-line
Chèn một dòng trắng giữa các đoạn tài liệu. Không có tác dụng nếu tập tin đầu vào
không sử dụng đoạn (thẻ <p> hoặc <div>).
--insert-blank-line-size
Set the height of the inserted blank lines (in em). The height of the lines between
paragraphs will be twice the value set here.
--keep-ligatures
Preserve ligatures present in the input document. A ligature is a special rendering
of a pair of characters like ff, fi, fl et cetera. Most readers do not have support
for ligatures in their default fonts, so they are unlikely to render correctly. By
default, calibre will turn a ligature into the corresponding pair of normal
characters. This option will preserve them instead.
--line-height
The line height in pts. Controls spacing between consecutive lines of text. Only
applies to elements that do not define their own line height. In most cases, the
minimum line height option is more useful. By default no line height manipulation
is performed.
--linearize-tables
Một số tài liệu được làm cẩu thả dùng bảng để điều chỉnh vị trí chữ trên trang. Khi
chuyển đổi sang định dạng khác, các tài liệu này thường có chữ nằm ngoài trang và
các lỗi khác. Tuỳ chọn này sẽ tách nội dung trong các bảng đó và sắp xếp dưới dạng
liệt kê.
--margin-bottom
Set the bottom margin in pts. Default is 5.0. Setting this to less than zero will
cause no margin to be set (the margin setting in the original document will be
preserved). Note: Page oriented formats such as PDF and DOCX have their own margin
settings that take precedence.
--margin-left
Set the left margin in pts. Default is 5.0. Setting this to less than zero will
cause no margin to be set (the margin setting in the original document will be
preserved). Note: Page oriented formats such as PDF and DOCX have their own margin
settings that take precedence.
--margin-right
Set the right margin in pts. Default is 5.0. Setting this to less than zero will
cause no margin to be set (the margin setting in the original document will be
preserved). Note: Page oriented formats such as PDF and DOCX have their own margin
settings that take precedence.
--margin-top
Set the top margin in pts. Default is 5.0. Setting this to less than zero will
cause no margin to be set (the margin setting in the original document will be
preserved). Note: Page oriented formats such as PDF and DOCX have their own margin
settings that take precedence.
--minimum-line-height
The minimum line height, as a percentage of the element's calculated font size.
calibre will ensure that every element has a line height of at least this setting,
irrespective of what the input document specifies. Set to zero to disable. Default
is 120%. Use this setting in preference to the direct line height specification,
unless you know what you are doing. For example, you can achieve "double spaced"
text by setting this to 240.
--remove-paragraph-spacing
Xóa khoảng trắng giữa các đoạn tài liệu. Đồng thời thụt vào đầu đoạn một khoảng
1.5em. Nếu tập tin đầu vào không sử dụng đoạn (thẻ <p> hoặc <div>), phần mềm không
thể xóa khoảng trắng.
--remove-paragraph-spacing-indent-size
When calibre removes blank lines between paragraphs, it automatically sets a
paragraph indent, to ensure that paragraphs can be easily distinguished. This
option controls the width of that indent (in em). If you set this value negative,
then the indent specified in the input document is used, that is, calibre does not
change the indentation.
--smarten-punctuation
Convert plain quotes, dashes and ellipsis to their typographically correct
equivalents. For details, see https://daringfireball.net/projects/smartypants.
--subset-embedded-fonts
Subset all embedded fonts. Every embedded font is reduced to contain only the
glyphs used in this document. This decreases the size of the font files. Useful if
you are embedding a particularly large font with lots of unused glyphs.
--transform-css-rules
Path to a file containing rules to transform the CSS styles in this book. The
easiest way to create such a file is to use the wizard for creating rules in the
calibre GUI. Access it in the "Look & feel->Transform styles" section of the
conversion dialog. Once you create the rules, you can use the "Export" button to
save them to a file.
--transform-html-rules
Path to a file containing rules to transform the HTML in this book. The easiest way
to create such a file is to use the wizard for creating rules in the calibre GUI.
Access it in the "Look & feel->Transform HTML" section of the conversion dialog.
Once you create the rules, you can use the "Export" button to save them to a file.
--unsmarten-punctuation
Convert fancy quotes, dashes and ellipsis to their plain equivalents.
HEURISTIC PROCESSING
Modify the document text and structure using common patterns. Disabled by default. Use
--enable-heuristics to enable. Individual actions can be disabled with the --disable-*
options.
--disable-dehyphenate
Analyze hyphenated words throughout the document. The document itself is used as a
dictionary to determine whether hyphens should be retained or removed.
--disable-delete-blank-paragraphs
Remove empty paragraphs from the document when they exist between every other
paragraph
--disable-fix-indents
Turn indentation created from multiple non-breaking space entities into CSS
indents.
--disable-format-scene-breaks
Left aligned scene break markers are center aligned. Replace soft scene breaks that
use multiple blank lines with horizontal rules.
--disable-italicize-common-cases
Look for common words and patterns that denote italics and italicize them.
--disable-markup-chapter-headings
Detect unformatted chapter headings and sub headings. Change them to h2 and h3
tags. This setting will not create a TOC, but can be used in conjunction with
structure detection to create one.
--disable-renumber-headings
Looks for occurrences of sequential <h1> or <h2> tags. The tags are renumbered to
prevent splitting in the middle of chapter headings.
--disable-unwrap-lines
Unwrap lines using punctuation and other formatting clues.
--enable-heuristics
Enable heuristic processing. This option must be set for any heuristic processing
to take place.
--html-unwrap-factor
Scale used to determine the length at which a line should be unwrapped. Valid
values are a decimal between 0 and 1. The default is 0.4, just below the median
line length. If only a few lines in the document require unwrapping this value
should be reduced
--replace-scene-breaks
Replace scene breaks with the specified text. By default, the text from the input
document is used.
SEARCH AND REPLACE
Modify the document text and structure using user defined patterns.
--search-replace
Path to a file containing search and replace regular expressions. The file must
contain alternating lines of regular expression followed by replacement pattern
(which can be an empty line). The regular expression must be in the Python regex
syntax and the file must be UTF-8 encoded.
--sr1-replace
Replacement to replace the text found with sr1-search.
--sr1-search
Search pattern (regular expression) to be replaced with sr1-replace.
--sr2-replace
Replacement to replace the text found with sr2-search.
--sr2-search
Search pattern (regular expression) to be replaced with sr2-replace.
--sr3-replace
Replacement to replace the text found with sr3-search.
--sr3-search
Search pattern (regular expression) to be replaced with sr3-replace.
STRUCTURE DETECTION
Điều chỉnh tự động nhận dạng cấu trúc văn bản.
--chapter
An XPath expression to detect chapter titles. The default is to consider <h1> or
<h2> tags that contain the words "chapter", "book", "section", "prologue",
"epilogue" or "part" as chapter titles as well as any tags that have
class="chapter". The expression used must evaluate to a list of elements. To
disable chapter detection, use the expression "/". See the XPath Tutorial in the
calibre User Manual for further help on using this feature.
--chapter-mark
Chỉ ra cách đánh dấu chương sách. Giá trị "pagebreak" sẽ chèn ngắt trang trước mỗi
chương. Giá trị "rule" sẽ chèn một đường kẻ trước mỗi chương. Giá trị "none" vô
hiệu hóa việc đánh dấu chương, giá trị "both" chèn cả ngắt trang và đường kẻ để
đánh dấu chương.
--disable-remove-fake-margins
Some documents specify page margins by specifying a left and right margin on each
individual paragraph. calibre will try to detect and remove these margins.
Sometimes, this can cause the removal of margins that should not have been removed.
In this case you can disable the removal.
--insert-metadata
Insert the book metadata at the start of the book. This is useful if your e-book
reader does not support displaying/searching metadata directly.
--page-breaks-before
An XPath expression. Page breaks are inserted before the specified elements. To
disable use the expression: /
--prefer-metadata-cover
Ưu tiên sử dụng bìa sách được tìm ra từ tập tin đầu vào hơn là bìa đã được định
trước.
--remove-first-image
Remove the first image from the input e-book. Useful if the input document has a
cover image that is not identified as a cover. In this case, if you set a cover in
calibre, the output document will end up with two cover images if you do not
specify this option.
--start-reading-at
An XPath expression to detect the location in the document at which to start
reading. Some e-book reading programs (most prominently the Kindle) use this
location as the position at which to open the book. See the XPath tutorial in the
calibre User Manual for further help using this feature.
TABLE OF CONTENTS
Điều chỉnh quá trình tự tạo Mục Lục. Mặc định, nếu tập tin nguồn đã có sẵn Mục Lục, nó sẽ
được sử dụng thay vì tự động tạo Mục Lục mới.
--duplicate-links-in-toc
When creating a TOC from links in the input document, allow duplicate entries, i.e.
allow more than one entry with the same text, provided that they point to a
different location.
--level1-toc
XPath expression that specifies all tags that should be added to the Table of
Contents at level one. If this is specified, it takes precedence over other forms
of auto-detection. See the XPath Tutorial in the calibre User Manual for examples.
--level2-toc
XPath expression that specifies all tags that should be added to the Table of
Contents at level two. Each entry is added under the previous level one entry. See
the XPath Tutorial in the calibre User Manual for examples.
--level3-toc
XPath expression that specifies all tags that should be added to the Table of
Contents at level three. Each entry is added under the previous level two entry.
See the XPath Tutorial in the calibre User Manual for examples.
--max-toc-links
Số liên kết được chèn vào Mục Lục. Gán 0 để vô hiệu hóa. Mặc định: 50. Liên kết chỉ
được thêm vào Mục Lục nếu số chương được tìm ra nhỏ hơn ngưỡng bạn đã chọn.
--no-chapters-in-toc
Không thêm những chương được phần mềm tự tìm ra vào Mục Lục.
--toc-filter
Remove entries from the Table of Contents whose titles match the specified regular
expression. Matching entries and all their children are removed.
--toc-threshold
Nếu số chương được tìm ra nhỏ hơn ngưỡng này, các liên kết sẽ được thêm vào Mục
Lục. Mặc định: 6
--use-auto-toc
Thông thường, nếu tập tin nguồn đã có sẵ Mục Lục, nó sẽ được sử dụng thay cho Mục
Lục tự tạo. Tuỳ chọn này sẽ khiến phần mềm luôn sử dụng Mục Lục tự tạo.
