Impress 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%
tends to work well with photographs (small file size, little perceptible loss).
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 (Encapsulated PostScript) 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 for long-term preservation of documents,
by embedding all the information necessary for faithful reproduction (such as
fonts) while forbidding other elements (including forms, security, and
encryption). PDF tags are written. If you select PDF/A-1, the forbidden
elements are grayed-out (not available).
Tagged PDF: Tagged PDF contains information about the structure of the
document’s contents. This can help to display the document on devices with
different screens, and when using screen reader software. 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: Exports slide names as “bookmarks” (a table of contents
list displayed by some PDF readers, including Adobe Reader).
Export comments: Exports comments as PDF notes. You may not want this!
Export notes pages: Exports a set of Notes pages after the set of slides.
Export automatically inserted blank pages: Not used in Impress.
Embed standard fonts: In previous versions of OOo, the standard fonts
(Times, Helvetica, Courier, Symbol, and ZapfDingbats) were only embedded
into the PDF when the resulting file was of the PDF/A type, since the PDF/A
standards requires this. In version 3.3, you can choose to embed these fonts in
all PDF documents created by OOo to enhance display accuracy in PDF
viewers.
Initial View page of PDF Options dialog box
On the Initial View page (Figure 198), you can choose how the PDF opens by default
in a PDF viewer. The selections should be self-explanatory.
