EBOOK-CONVERT(1) calibre EBOOK-CONVERT(1) NAME 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 E-book 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. o TU CHN NHP o TU CHN XUT o LOOK AND FEEL o HEURISTIC PROCESSING o SEARCH AND REPLACE o STRUCTURE DETECTION o TABLE OF CONTENTS o METADATA o DEBUG --help, -h show this help message and exit --input-profile Xac dnh h so nhp.

You can create an e-book from a builtin recipe like this: ebook-convert "Recipe Name.recipe" output.epub --output-profile Specify the output profile. The output profile tells the conversion system how to optimize the created document for the specified device. In some cases, an output profile can be used to optimize the output for a particular device, but this is rarely necessary. Choices are:cybookg3, cybook_opus, default, generic_eink, generic_eink_hd, generic_eink_large, hanlinv3, hanlinv5, illiad, ipad, ipad3, irexdr1000, irexdr800, jetbook5, kindle, kindle_dx, kindle_fire, kindle_oasis, kindle_pw, kindle_pw3, kindle_scribe, kindle_voyage, kobo, msreader, mobipocket, tablet, nook, nook_color, nook_hd_plus, pocketbook_inkpad3, pocketbook_lux, pocketbook_hd, pocketbook_900, pocketbook_pro_912, galaxy, sony, sony300, sony900, sony-landscape, sonyt3 --version show program's version number and exit TU CHN NHP Cac tu chn diu chnh x ly ca tp tin nhp mobi --input-encoding Xac dnh bng ma ca tp tin duc nhp vao.

TU CHN XUT Cac tu chn diu chnh x ly ca tp tin xut 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-max-image-size The maximum image size (width x height). A value of none means use the screen size from the output profile. A value of profile means no maximum size is specified. For example, a value of 100x200 will cause all images to be resized so that their width is no more than 100 pixels and their height is no more than 200 pixels. Note that this only affects the size of the actual image files themselves. Any given image may be rendered at a different size depending on the styling applied to it in the document. --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 Thong thung, nu cac tp tin ngun khong co bia sach va bn khong ch dnh truc, mt bia mc dnh duc to ra vi tieu d, tac gi,...Chn d vo hiu hoa chc nang nay. --no-svg-cover Khong s dng SVG cho bia sach.

Nu khong chn, nhng thit b tren s hin th bia nhu la mt trang trng. --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 Nu duc thit lp, plugin xut d liu s to tp tin xut d dc nht co th. Co th khong co hiu lc vi mt s plugin xut d liu. --toc-title Title for any generated inline table of contents. LOOK AND FEEL Cac tu chn diu chnh theo tri nghim cho tp tin xut --asciiize Transliterate Unicode characters to an ASCII representation. Use with care because this will replace Unicode characters with ASCII. For instance it will replace "Pele" 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 di cach canh l ch. Gia tr "left": canh l trai. Gia tr "justify": canh du. Gia tr "original" (mc dnh) gi nguyen l tai liu trong tp tin du vao. Chu y: Chc nang canh l ch co trong mt vai dnh dng xut. --disable-font-rescaling Khong t di c 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 Chen mt dong trng gia cac don tai liu. Khong co tac dng nu tp tin du vao khong s dng don (th

hoc

). --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 combined character 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. Note that ligatures here mean only unicode ligatures not ligatures created via CSS or font styles. 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 Mt s tai liu duc lam cu th dung bng d diu chnh v tri ch tren trang. Khi chuyn di sang dnh dng khac, cac tai liu nay thung co ch nm ngoai trang va cac li khac. Tu chn nay s tach ni dung trong cac bng do va sp xp dui dng lit ke. --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 Xoa khong trng gia cac don tai liu. Dng thi tht vao du don mt khong 1.5em. Nu tp tin du vao khong s dng don (th

hoc

), phn mm khong th xoa khong trng. --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

or

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 Diu chnh t dng nhn dng cu truc van bn. --add-alt-text-to-img When an tag has no alt attribute, check the associated image file for metadata that specifies alternate text, and use it to fill in the alt attribute. The alt attribute is used by screen readers for assisting the visually challenged. --chapter An XPath expression to detect chapter titles. The default is to consider

or

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 Ch ra cach danh du chuong sach. Gia tr "pagebreak" s chen ngt trang truc mi chuong. Gia tr "rule" s chen mt dung k truc mi chuong. Gia tr "none" vo hiu hoa vic danh du chuong, gia tr "both" chen c ngt trang va dung k d danh du chuong. --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 Uu tien s dng bia sach duc tim ra t tp tin du vao hon la bia da duc dnh truc. --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 Diu chnh qua trinh t to Mc Lc. Mc dnh, nu tp tin ngun da co sn Mc Lc, no s duc s dng thay vi t dng to Mc Lc mi. --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 S lien kt duc chen vao Mc Lc. Gan 0 d vo hiu hoa. Mc dnh: 50.
