Sub-setting:
PDFDevice is capable of sub-setting and embedding true-type
fonts. The sub-setting of font data is the process that disassembles font
data for a particular font used in the PDF output and re-assembling only
with the minimum data that is required to render the actual characters in
the output, greatly reducing the file size without compromising document
appearance.
Embed licensed fonts:
Typically, most fonts installed as part of the operating system are fully licensed for sub-setting and
embedding in PDF files. However, some fonts that have been purchased or downloaded may not permit this.
This setting ignores this state and forces PDFDevice to embed such fonts.
(You should only override
this setting if you are certain that you own a license that allows you to embed the
font in question.)
Substitute fonts: (new for
version 3)
PDFDevice provides an option to substitute non-true-type fonts with true-type fonts
that have similar characteristics for the purpose of font embedding.
