Notes PDF 1.7 Adobe goes ISO

Probably the most ‘unexciting’ PDF-version to ever be released, PDF 1.7 contained
improved support for commenting and security. Support for 3D also got improved,
with the possibility to add comments to 3D-objects and more elaborate control over 3D
animations. A PDF 1.7 file can include default printer settings such as paper selection,
number of copies, scaling,
One interesting development with PDF 1.7 is the fact that it became an official ISO-standard
(ISO 32000-1:2008) in January 2008. The official specs were released on 1 July. James King
from Adobe posted some interesting background information about this on his blog.

• Dynamic construction of PDF files opens the door to many applications. You can create
almost any kind of business document, including form letters, invoices, and receipts. Most
paperwork that involves filling out a paper form can be automated by overlaying text
onto a scan of the paper form and saving the result as a PDF file.
• Text is the heart of a PDF file. As such, there are many options for changing the appearance
and layout of text.
