2.In the Project Options dialog, in the left sidebar, under Printed Manual, click PDF Export.
3.Change the parameters that you need.
Below is a description of the parameters in this section.
Specifies whether to export the table of contents to the PDF Outline items. In Adobe Reader the document outline is available on the Bookmarks tab.
Allows you to select how the PDF document should be displayed when the reader opens it.
Defines the compression mode to use for the PDF file. By using compression, the PDF file will be reasonable smaller. On the other hand, compression will create binary data rather than ASCII data. While the "Flate" mode produces the smallest files, the "Run-Length" mode compression is compatible with old PDF reader programs.
Enables the encryption of the PDF document.
This password is required to edit an encrypted PDF file. If you do not set the owner password, the password will be randomly created.
This password is used to encrypt the PDF file. If you do not provide a user password, the rights for the user can be still restricted using "Encryption". But the user will then not be prompted for a password.
These options specify the user rights for an encrypted PDF document.
You can protect the PDF document from viewing if you also set the property User Password or you can simply prohibit copying.
You can decide whether True Type fonts should be embedded in the PDF file or not. If fonts are not embedded in the PDF file, text can be displayed wrongly if the used fonts are not installed on the PC of the reader of the PDF file. On the other hand embedded fonts causes the PDF file to be much larger (the size of a usual font file is 150KB). The font embedding also slows the PDF creation process down.
You can select one of the following Font Embedding modes:
Use True Type Fonts
Use True Type fonts but do not embed the font data.
Embed True Type Fonts
Embed data of all used fonts (you can still exclude certain fonts).
Embed Only Symbol True Type Fonts
Embed only symbol True Type fonts such as WingDings, etc.
Embed Only Used True Type Characters
Embed only those characters which have been used in the document (produces the smallest PDF file).
CID Font Embedding for Unicode Fonts
The CID font embedding option can be used with fonts that contain the full Unicode character set. This option embeds only the characters that are actually used in your help project, using a special encoding mode based on Character IDs (CID).
For Unicode fonts containing the full character set, this option can reduce the size of the PDF file.
However, if you use fonts that do not contain some characters (for example, the characters for the language that you are using), such characters will be exported into the PDF document as glyphs, which disables the possibility to select or copy them, and also can make the size of the PDF file larger.
You can use the CID Font Embedding option in case some characters for the language that you are using are not displayed correctly. However, instead of using this option, you can also try to use a different font that contains the characters you need to display. Usually, this option should NOT be used for Asian languages, Russian, and Greek.
Allows you to define font names (one per line) that will not be embedded to the PDF file (even when using the Embed True Type Fonts mode). This option is useful to exclude certain standard fonts which you expect to be installed on the system the PDF document will be viewed. Please note that symbol fonts should be embedded since they cannot be substituted.
