</tr>
12.5 Annotations
12.5.1 General
Change the last paragraph as follows:
These descriptions assume the page is being viewed in the orientation specified by the Rotate entry. Conceptually, the behaviour of each annotation type may be
implemented by a software module called an annotation handler. A PDF processor shall provide annotation handlers for all of the conforming annotation types.
The set of annotation types is extensible. An interactive PDF processor shall provide certain expected behaviour for all annotation types that it does not
recognise, as documented in 12.5.2, "Annotation dictionaries"
12.5.5, "Appearance streams" and "Table 167 - Annotation flags" (bit positions 1 and 2)
.
12.5.2 Annotation dictionaries
Change Table 166 as follows:
| Key | Type | Value |
|---|---|---|
| AP | dictionary |
( Every annotation (including those whose Subtype value is Widget, as used for form fields), except for the two cases listed below, shall have at least one appearance dictionary.
NOTE (2020) The bullet point above was changed from "or" to "and" in this document to match requirements in other published ISO PDF standards (such as PDF/A). Array indices were also corrected to be zero-based as described in 3.2 "array object".
|
Change the paragraph and NOTEs below Table 166 as follows:
A PDF reader shall render the appearance dictionary without regard to any other keys and values in the annotation dictionary and
When rendering the appearance dictionary, a PDF reader
shall ignore the values of the C, IC, Border, BS, BE,
BM,
CA, ca, H, DA, Q, DS, LE, LL, LLE,
MK,
and Sy keys.
NOTE 1 Some of these keys are only relevant to certain annotation subtypes as described in the following subclauses.
NOTE 2 Requiring an appearance dictionary for each annotation ensures the reliable rendering of the annotations. When an appearance dictionary is not present, the rendered appearance will be implementation dependent.
12.5.6.2 Markup annotations
Change the paragraph below NOTE 1 as follows:
When providing the Contents key, if separating text into paragraphs, a CARRIAGE RETURN (0Dh) shall be used and not, for example, a LINE FEED character (0Ah).
...
12.5.6.5 Link annotations
Change Table 176 as follows:
| Key | Type | Value |
|---|---|---|
| QuadPoints | array |
(Optional; PDF 1.6) An array of 8 × n numbers specifying the coordinates of n quadrilaterals in default user space that comprise
the region in which the link should be activated. The coordinates for each quadrilateral are given in the order: NOTE 1 When QuadPoints is used, the activation area and the visual appearance (including border) of the link annotation are not required to be the same. NOTE 2 The last paragraph above was clarified in this document (2020). |
12.5.6.6 Free text annotations
Change Table 177 as follows:
| Key | Type | Value |
|---|---|---|
| DA | string |
(Required) The default appearance string that shall be used in formatting the text (see 12.7.4.3, "Variable text"). The annotation dictionary's AP entry |
12.5.6.18 Screen annotations
Change the last bullet below Table 190 as follows:
- ...
-
The AP entry refers to an appearance dictionary (see "Table 170 - Entries in an appearance dictionary") whose normal appearance provides the visual
appearance for a screen annotation that shall be used for printing and default display when a media clip is not being played.
If AP is not present, the screen annotation shall not have a default visual appearance and shall not be printed.
12.5.6.24 Projection annotations
Change the first paragraph as follows:
A projection annotation (PDF 2.0) is a markup annotation subtype (see 12.5.6.2, "Markup annotations") that has much of the functionality of other markup annotations. However, a projection annotation is only valid within the context of an associated run-time environment, such as an activated 3D model, and thus an AP dictionary is not required.
...
Delete the last paragraph as follows:
A projection annotation with a Rect entry that has zero height or zero width shall not have an AP dictionary.
12.6 Actions
12.6.4 Action types
12.6.4.2 Go-To actions

Change Table 242 as follows:
| Bit position | Name | Meaning |
|---|---|---|
| 1 | Include/Exclude |
If clear, the Fields array (see "Table 241 — Additional entries specific to a reset-form action") specifies which fields to reset. (All descendants of the specified fields in the field hierarchy are reset as well.) If set, the Fields array indicates which fields to exclude from resetting; that is, all fields in the document’s interactive form shall be reset except those listed in the Fields array. (All descendants of the specified fields in the field hierarchy are also exempt from being reset.) |

12.7.9 Non-interactive forms
Change the first paragraph as follows:

PrintField attrib0ute (14.8.5.6, "PrintField attributes") for repurposing and accessibility purposes.
12.8.1 General
Change the list item below NOTE 2 as follows:
A PDF document may contain the following standard types of signatures:
...
- Any number of document timestamp signatures, see 12.8.5, "Document timestamp (DTS) dictionary". The timestamp signature dictionary of a document timestamp signature shall be the value of a signature field and shall contain a ByteRange entry. These shall follow the certification signature if one is present.
