Controlling PDF content and quality

For more control over the content and quality of the resulting PDF, use File > Export as PDF. The PDF Options dialog opens. This dialog has five pages, described in this section. Make your selections, and then click Export. Then you are asked to enter the location and file name of the PDF to be created, and click Save to export the file.

General page of PDF Options dialog

On the General page, you can choose which pages (slides) to include in the PDF, the type of compression to use for images (which affects the quality of images in the PDF), and other options.

General page of PDF Options dialog.

Range section

  • All: Exports the entire document.
  • Pages: To export a range of slides, use the format 3-6 (pages 3 to 6). To export single slides, use the format 7;9;11 (pages 7, 9, and 11). You can also export a combination of slide ranges and single slides, by using a format like 3-6;8;10;12.
  • Selection: Exports whatever material is selected.

Images section

  • Lossless compression: Images are stored without any loss of quality. Tends to make large files when used with photographs. Recommended for other images.
  • 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.
Image:documentation_note.png 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 forbiden elements are greyed-out (not available).
  • 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: Exports slide names as “bookmarks” (a table of contents list displayed by some PDF readers, including Adobe Reader).
  • Export notes: Exports a set of Notes after the set of slides.
  • Export automatically inserted blank pages: Not used in Impress.

Initial View page of PDF Options dialog

On the Initial View page, you can choose how the PDF opens by default in a PDF viewer. The selections should be self-explanatory.

User Interface page of PDF Options dialog

On the User Interface page, you can choose more settings to control how a PDF viewer displays the file. Some of these choices are particularly useful when you are creating a PDF to be used as a presentation or a kiosk-type display.

User Interface page

Window options section

  • Resize window to initial page. Causes the PDF viewer window to resize to fit the first page of the PDF.
  • Center window on screen. Causes the PDF viewer window to be centered on the computer screen.
  • Open in full screen mode. Causes the PDF viewer to open full-screen instead of in a smaller window.
  • Display document title. Causes the PDF viewer to display the document’s title in the title bar.

User interface options section

  • Hide menubar. Causes the PDF viewer to hide the menu bar.
  • Hide toolbar. Causes the PDF viewer to hide the toolbar.
  • Hide window controls. Causes the PDF viewer to hide other window controls.

Transitions

Includes Impress slide transition effects as the respective PDF effects.

Bookmarks

Select how many heading levels are displayed as bookmarks, if Export bookmarks is selected on the General page.

Links page of PDF Options dialog

On this page you can choose how links are exported to PDF.

Links page of PDF Options dialog.

Export bookmarks as named destinations

If you have defined slide names, this option exports them as “named destinations” to which Web pages and PDF documents can link.

Convert document references to PDF targets

If you have defined links to other documents with OpenDocument extensions (such as .ODT, .ODS, and .ODP), this option converts the files names to .PDF in the exported PDF document.

Export URLs relative to file system

If you have defined relative links in a document, this option exports those links to the PDF.

Cross-document links

Defines the behavior of links clicked in PDF files.

Security page of PDF Options dialog

PDF export includes options to encrypt the PDF (so it cannot be opened without a password) and apply some digital rights management (DRM) features.

  • With an open password set, the PDF can only be opened with the password. Once opened, there are no restrictions on what the user can do with the document (for example, print, copy, or change it).
  • With a permissions password set, the PDF can be opened by anyone, but its permissions can be restricted.
  • With both the open password and permission password set, the PDF can only be opened with the correct password, and its permissions can be restricted.

Image:documentation_note.png Permissions settings are effective only if the user’s PDF viewer respects the settings.

The figure below shows the pop-up dialog displayed when you click the Set open password button on the Security page of the PDF Options dialog.

After you set a password for permissions, the other choices on the Security page become available. These selections should be self-explanatory.
