LaTeX Export
Exports the current document in LaTeX 2e format. A LaTeX document can be typeset with the TeX typesetting system.
Choose File - Export - LaTeX 2e
General
LaTeX format
Select the general format for the LaTeX document
Conceptually, %PRODUCTNAME Writer and LaTeX are quite different. A LaTeX document is usually based on a certain "document class", that determines the general layout and formatting of the document. In addition the use of several LaTeX packages may change various aspects of the LaTeX document.
The result of a conversion into LaTeX will thus depend very much on which LaTeX packages are used and how much formatting it is desired to preserve.
Writer2LaTeX offers a number of default formats, all based on the standard LaTeX document class "article". Each of the formats defines the LaTeX packages to use and the handling of formatting.
- Ultra-clean article
  will create a very basic LaTeX article, with almost no formatting preserved.
- Clean article
  will also create a default LaTeX article, but does preserve some basic formatting from the %PRODUCTNAME Writer document, such as boldface, color and hyperlinks.
- Default
  creates a LaTeX article preserving as much formatting as it is possible without any significant deviations from LaTeX standards.
- Print optimized
  on the other hand creates a LaTeX article preserving as much formatting as possible. The result will resemble the %PRODUCTNAME Writer document, but will look slightly different from a standard LaTeX article (and the LaTeX code will be less readable).
- Screen optimized (pdf)
  also creates a LaTeX article preserving most of the formatting, but optimized for screen viewing (using the package pdfscreen) rather than printing.
- Custom
  is a user defined format. To configure the custom format, choose Tools - Options - Writer2LaTeX.
Expert users can extend the list with further formats using configuration packages. See the documentation on the web site for Writer2LaTeX.
Backend
Select the final format of the exported document
When processing a LaTeX document, the final result is a document in a certain backend format. The handling of certain aspects of the document, in particular graphics, depends on the backend. With this option you can select the backend format.
- Generic
  will create a LaTeX document that can be processed with any flavour of LaTeX, usually with a file in DVI format as the result. Graphics is not supported with this backend.
- Pdf (pdfTeX)
  will create a LaTeX document that is suitable for processing with pdfLaTeX. Graphics are converted to a format that can be included in pdf files.
- Postscript (dvips)
  will create a LaTeX document that is suitable for generating documents in Postscript format, usually by post processing with dvips. Graphics will be converted to Encapsulated postscript format.
- Unspecified
  will create a LaTeX document with no particular backend in mind. All graphics will be exported in the original format, and it is up to the user to handle them.
If you have selected the format Screen optiomized (pdf), you cannot select the backend, which will always be pdf.
Encoding
Select the character encoding of the LaTeX file
A LaTeX document is a text file, which always uses a certain character encoding. The character encoding is important if the LaTeX file is going to be edited in a text editor: You should select an encoding that is supported by your text editor. This setting is also important to get optimal support for international characters: If you for example use pdfTeX, searching in the final pdf document will only work for characters supported by the selected character encoding. Currently, Writer2LaTeX supports 8 different encodings which together are suitable for a large number of languages written with either latin, greek or cyrillic letters.
The supported character encodings are US ASCII, West European (ISO 8859-1), East European (ISO 8859-2), Latin/Greek (ISO 8859-7), Microsoft East European (Cp1250), Microsoft Cyrillic (Cp1251), Russian (koi8-r) and Unicode (UTF8).
If you have selected XeTeX as your backed, the character encoding is always UTF-8. XeTeX is needed for asian (CJK) and bidirectional (CTL) scripts.
Enable multilingual support
Check this if your document contains text in more than one language
If you check this option, all the language settings in the %PRODUCTNAME Writer document will be exported to LaTeX. Sometimes the language settings in a %PRODUCTNAME Writer document are not correct, so if you have a document that is written in one language only you may want to uncheck this option. This will produce a cleaner LaTeX file because you may avoid a large number of language selections.
Use greek letters as symbols
Check this treat greek characters as symbols rather than as text
Greek letters used in latin text are often used as symbols, such as the number π or the word γ-radiation. By checking this option (not available if XeTeX is the backend), all greek letters used within latin or cyrillic text will be treated as mathematical symbols, which will produce a slightly better result – and also not require that greek text fonts are available in the LaTeX installation. This option has no effect on greek text (provided the language is set correctly in the %PRODUCTNAME Writer document).
Support additional symbols
Check this to add support for additonal symbols (e.g. phonetic symbols, smileys)
If you select this option (not available if XeTeX is the backend), LaTeX will load some additional packages containing support for various symbols: A better looking euro-symbol, phonetic characters, dingbats and various other symbols and geometric shapes.
Bibliography
Use BibTeX for bibliography
Check this to export the bibliography to BibTeX format
Usually the bibliography in a LaTeX document is generated by the companion program BibTeX. If you check this option, all the bibliographic references will be exported to BibTeX format for later processing with the BibTeX program.
BibTeX style
Enter the name of a BibTeX style to format the bibliography
If you use BibTeX, you should also select a BibTeX style to be used when generating the bibliography. Select one of the predefined styles plain, unsrt, alpha or abbrv or type the name of any BibTeX style which is available in your LaTeX installation.
Files
Wrap long lines
Check this if you want to wrap long lines in the LaTeX file
Checking this option wraps long lines in the generated LaTeX file. This enhances the readability if the file is later edited in a text editor. If you use a text editor that wraps lines automatically, you should uncheck this option.
After characters
Enter the number of characters after which the lines should be wrapped
If you choose to wrap long lines, they will be wrapped as soon as possible after this number of characters.
Split document at linked sections
Check this to create a separate LaTeX file for each linked section
Checking this option will create separate LaTeX files for sections in the %PRODUCTNAME Writer document with linked content. This can be an advantage if the LaTeX document is later edited in a text editor.
Split document at top level sections
Check this to create a separate LaTeX file for all sections that are not nested inside another section
Checking this option will create separate LaTeX files for all top level sections in the %PRODUCTNAME Writer document (but not for nested sections).
Save images in subdirectory
Check this to save the documents in a separate subdirectory
Writer2LaTeX normally saves images associated with the document in the same directory as the LaTeX document. If the document contains a large number of images it may be more convenient to save the images in a separate subdirectory. This option will create a subdirectory with the same name as the LaTeX document to store the images.
Special content
Export notes
Select how to export notes in the document
This option determines how to export notes (also known as annotations) in the %PRODUCTNAME Writer document.
- Do not export
  will ignore the notes.
- As comments
  will export the notes as comments in the LaTeX file. They will not be visible in the final document after processing with LaTeX.
- As marginal notes
  will put the notes in the margin of the document. In this case they will be visible in the final document, but beware that the notes will be lost if the margin is too narrow.
- As pdf annotations
  will export the notes as pdf text annotations. If the pdf viewer supports it, you will be able to read the notes. Adobe Reader displays text annotations with a yellow icon, which allows you to open and read the note. If the document is not processed with pdfTeX, the notes will be converted to marginal notes.
Export document properties (metadata)
Check this if you want to export meta data associated with the document
If you check this option, Writer2LaTeX will export the title, author and date of the document as found under File – Properties. Furthermore, if you have chosen pdf as the backend, the title, author, subject and keywords will be exported to the pdf document and will be viewable if the pdf viewer supports it. If the option is not checked, only the title will be exported.
Figures and tables
Use original image size
Select this option to use the original image size (the size specified in the document will be ignored)
Often images in a %PRODUCTNAME Writer document are scaled up or down from their original size. Normally the same scaling will be used in the LaTeX document, but if you select this option, the original (unscaled) image size will be used.
Optimize simple tables
Check this to optimize the width of tables
Normally Writer2LaTeX will generate tables with the same column widths as in the original document. For tables with simple content it may be more desirable to create tables which are as narrow as possible, with only one line of text per cell. Compare the table

Simple content
Simple content

to the optimized table

Simple content
Simple content
Simple content

If you check this option, Writer2LaTeX will try to optimize tables.
Maximum width in characters
Enter the maximum width in characters of tables that should have optimized their width
If you have chosen to optimize simple tables, you have to specify the maximum width of the table, measured in the number of characters. If you for example set the number to 50, only tables with a total width of 50 or fewer characters will be optimized.
Float tables
Check this to allow tables to flow in the document
In %PRODUCTNAME Writer you can either choose that the rows of a table must be kept together on one page or that the table may split across page breaks. Keeping a table on one page may be desirable to increase the readability of the table, but it may also leave large white gaps at the bottom of the page. In LaTeX this problem is solved with floating tables: A table can automatically move to another position which fixes the whitespace problem. If you check this option, all tables that are not allowed to break across pages are exported as floating tables.
Float figures
Check this to allow figures to flow in the document
A similar option is available for figures (graphics, text boxes). If you check this option, figures are converted to floating figures which can move in the document to reduce whitespace. This will not affect figures anchored as character.
Float placement
Select placement of floating tables and figures
If you choose to let either tables or figures float, use this option to specify the placement of the floats:
- Top or bottom of page
  will place the floats either at the top or the bottom of a page.
- Top of page
  will place floats at the top of a page.
- Bottom of page
  will place floats at the top of a page.
- Here or top of page
  will place floats at their original position, if there is room left on the page, and otherwise at the top of a page.
- Here or bottom of page
  will place floats at their original position, if there is room left on the page, and otherwise at the bottom of a page.
In all cases it might happen that LaTeX creates some special pages which only contains floats. This will usually be the case if there are many floats compared to the amount of text.
AutoCorrect
Ignore hard page breaks
Check this if you don't want to export manual page breaks
Hard (or manual) page breaks are often used to optimize page breaks in the final editing of a document. In this case you will probably not want to export these page breaks, as LaTeX creates page breaks that are quite different from the page breaks in %PRODUCTNAME Writer. If you select this option, hard page breaks will be ignored when exporting the document.
Ignore hard line breaks
Check this if you don't want to export manual line breaks
For similar reasons, you can select this option to ignore hard (manual) line breaks during export.
Ignore empty paragraphs
Check this if you don't want to export empty paragraphs
Empty paragraphs are sometimes used a simple means to create vertical spacing in %PRODUCTNAME Writer. In a well-structured document, an empty paragraph is probably a mistake. Hence you can select this option to ignore empty paragraphs in the document in the export. If you do not select the option, an empty paragraph is exported as vertical space.
Ignore double spaces
Check this if you don't want to export two consecutive space characters
For similar reasons you can choose to ignore two or more spaces in a row using this option.
