Export as PDF

Saves the current file to Portable Document Format (PDF) version 1.4. A PDF file can be viewed and printed on any platform with the original formatting intact, provided that supporting software is installed.

General tab

Range

Sets the export options for the pages included in the PDF file.

All

Exports all defined print ranges. If no print range is defined, exports the entire document.

Pages

Exports the pages you type in the box.

To export a range of pages, use the format 3-6. To export single pages, use the format 7;9;11. If you want, you can export a combination of page ranges and single pages, by using a format like 3-6;8;10;12.

Selection

Exports the current selection.

Images

Sets the PDF export options for images inside your document.

Lossless compression

Selects a lossless compression of images. All pixels are preserved.

JPEG compression

Quality

Enter the quality level for JPEG compression.

Reduce image resolution

Select to resample or down-size the images to a lower number of pixels per inch.

Select the target resolution for the images.

General

Sets general PDF export options.

Hybrid PDF (embed ODF file)

This setting enables you to export the document as a .pdf file containing two file formats: PDF and ODF. In PDF viewers it behaves like a normal .pdf file and it remains fully editable in Collabora Office.

Archive PDF/A-1a (ISO 19005-1)

Converts to the PDF/A-1a format. This is defined as an electronic document file format for long term preservation. All fonts that were used in the source document will be embedded into the generated PDF file. PDF tags will be written.

Tagged PDF (add document structure)

Select to write PDF tags. This can increase file size by huge amounts.

Tagged PDF contains information about the structure of the document contents. This can help to display the document on devices with different screens, and when using screen reader software.

Export bookmarks

Select to export bookmarks of Writer documents as PDF bookmarks. Bookmarks are created for all outline paragraphs (Tools - Chapter Numbering) and for all table of contents entries for which you did assign hyperlinks in the source document.

Export comments

Select to export comments of Writer and Calc documents as PDF notes.

To export comments of Writer documents as they are shown in Collabora Office, choose - Collabora Office Writer - Print and select the In margins option in the Comments area. The exported pages will be scaled down and the comments will be placed into their margins.

Create PDF form

Choose to create a PDF form. This can be filled out and printed by the user of the PDF document.

Submit format

Select the format of submitting forms from within the PDF file.

Select the format of the data that you will receive from the submitter: FDF (Forms Data Format), PDF, HTML, or XML.

This setting overrides the control's URL property that you set in the document.

Allow duplicate field names

Allows you to use the same field name for multiple fields in the generated PDF file. If disabled, field names will be exported using generated unique names.

Export automatically inserted blank pages

If switched on, automatically inserted blank pages are exported to the PDF file. This is best if you are printing the pdf file double-sided. Example: In a book a chapter paragraph style is set to always start with an odd numbered page. If the previous chapter ends on an odd page, Collabora Office inserts an even numbered blank page. This option controls whether to export that even numbered page or not.

Use reference XObjects

This option affects how PDF images are exported back to PDF. When this option is disabled, then the first page of the PDF data is included in the output. The PDF export merges the used images, fonts and other resources during export. This is a complex operation, but the result can be viewed in various viewers. When the option is enabled, then the reference XObject markup is used: this is a simple operation, but viewers have to support this markup to show vector images. Otherwise a fallback bitmap is shown in the viewer.

Digital Signatures tab

This tab contains the options related to exporting to a digitally signed PDF.

Digital signatures are used to ensure that the PDF was really created by the original author (i.e. you), and that the document has not been modified since it was signed.

The signed PDF export uses the keys and X.509 certificates already stored in your default key store location or on a smartcard.

When using a smartcard, it must already be configured for use by your key store. This is usually done during installation of the smartcard software.

Use this certificate to digitally sign PDF documents

Allows you to select a certificate to be used for signing this PDF export.

Select

Opens the Select Certificate dialog.

All certificates found in your selected key store are displayed. If the key store is protected by a password, you are prompted for it. When using a smartcard that is protected by a PIN, you are also prompted for that.

Select the certificate to use for digitally signing the exported PDF by clicking on the corresponding line, then click OK.

All other fields on the Digital Signatures tab will be accessible only after a certificate has been selected.

Certificate password

Enter the password used for protecting the private key associated with the selected certificate. Usually this is the key store password.

Location, Contact information, Reason

These three fields allow you to optionally enter additional information about the digital signature that will be applied to the PDF (Where, by whom and why it was made). It will be embedded in the appropriate PDF fields and will be visible to anyone viewing the PDF. Each or all of the three fields may be left blank.

Time Stamp Authority

Allows you to optionally select a Time Stamping Authority (TSA) URL.

During the PDF signing process, the TSA will be used to obtain a digitally signed timestamp that is then embedded in the signature. This (RFC 3161) timestamp will allow anyone viewing the PDF to verify when the document was signed.

The list of TSA URLs that can be selected is maintained under - Collabora Office - Security - TSAs.

If no TSA URL is selected (the default), the signature will not be timestamped, but will use the current time from your local computer.

Export button

Exports the current file in PDF format.
