Introduction to PDF 1.7 Features
1.2.2 Interactive Features
Several additions to markup annotations make them more suitable for technical
communication and review, or for use in a legal setting.
Interactive Features That Aid Technical Communication
Several additions to markup annotations aid technical communication and review:
•
The addition of dimension intents for polyline and polygon markup annota-
tions. Dimension intent supports the association of user-provided dimension
information with the line segments that compose polyline and polygon markup
annotations. This feature is similar to the dimension intent introduced for line
markup annotations in PDF 1.6.
•
The ability to specify units and scaling for the dimension intents of line,
polyline, and polygon markup annotations. This feature enables users to mea-
sure distances in the document, such as the width of an architectural diagram
or the diameter of a 3D cross section.
•
The ability to place markup annotations on specific views of 3D artwork
•
The ability to lock the contents of an annotation
Interactive Feature for Use in a Legal Setting
One addition to markup annotations is intended for use in a legal setting, espe-
cially banking. The addition of new viewer preference settings that specify print
characteristics, such as paper selection and handling, page range, copies, and
scaling. When a user prints a PDF document with those viewer preference set-
tings, the print dialog is pre-populated as specified in those settings. This capabil-
ity increases the predictability of how PDF documents are printed, which can
make PDF documents more suitable for use in a legal setting.
1.2.3 Accessibility Related Features
Additions to TaggedPDF identify the roles of more types of page content:
•
The ability to identify the roles of form fields in non-interactive PDF docu-
ments. This change identifies button fields (pushbuttons, check boxes and ra-
dio buttons) and text fields (populated or unpopulated).
