Writer Guide

Images section
• Lossless compression: Images are stored without any loss of
quality. Tends to make large files when used with photographs.
Recommended for other kinds of images or graphics.
• JPEG compression: Allows for varying degrees of quality. A
setting of 90% works well with photographs (small file size, little
perceptible loss of quality).
• Reduce image resolution: Lower-DPI (dots per inch) images
have lower quality. For viewing on a computer screen generally a
resolution of 72dpi (for Windows) or 96dpi (GNU/Linux) is
sufficient, while for printing it is generally preferable to use at
least 300 or 600 dpi, depending on the capability of the printer.
Higher dpi settings greatly increase the size of the exported file.
Note
EPS images with embedded previews are exported only as
previews. EPS images without embedded previews are
exported as empty placeholders.
General section
• PDF/A-1: PDF/A is an ISO standard established in 2005 for long-
term preservation of documents, by embedding all the pieces
necessary for faithful reproduction (such as fonts) while
forbidding other elements (including forms, security, encryption,
and tagged PDF). If you select PDF/A-1, the forbidden elements
are greyed-out (not available). Because the fonts are embedded in
the PDF file, the document will appear as the author intended
even if the machine where it is viewed does not support the
chosen font types.
• Tagged PDF: Exports special tags into the corresponding PDF
tags. Some tags that are exported are table of contents,
hyperlinks, and controls. This option can increase file sizes
significantly.
• Create PDF form - Submit format: Choose the format of
submitting forms from within the PDF file. This setting overrides
the control’s URL property that you set in the document. There is
only one common setting valid for the whole PDF document: PDF
(sends the whole document), FDF (sends the control contents),
HTML, and XML. Most often you will choose the PDF format.
• Export bookmarks: Creates PDF bookmarks for all outline
paragraphs and for all table of contents entries for which you
assigned hyperlinks.
