Constructor & Destructor Documentation

LinkAnnotation(Page page, Rect initialRect)

Parameters

page: Page: The page to which the LinkAnnotation is added.
initialRect: Rect: A rectangle specifying the annotation's bounds, specified in user space coordinates.

Create a new LinkAnnotation at the end of a page's annotation array. To create a LinkAnnotation and place it elsewhere in the page's annotation array, use the version of the constructor that takes an array position.

LinkAnnotation(Page page, Rect initialRect, int addAfter)

Parameters

page: Page: The page to which the annotation is added.
initialRect: Rect: A rectangle specifying the annotation's bounds, specified in user space coordinates.
addAfter: int: Where to add the annotation in the page's annotation array. To add the annotation to the end of the array, pass a value of -2 or use the alternate version of this constructor that does not take an index (this is generally what you should do unless you have a need to place the annotation at a special location in the array). Passing a value of -1 adds the annotation to the beginning of the array. Passing other negative values produces undefined results.

Create a new LinkAnnotation at a specific index in the page's annotation array.

Member Function Documentation

LinkAnnotation copyTo(Page destination)

Parameters

destination: Page: the page to copy the annotation to. The page may be in the same document as the source annotation or in a different document.

Returns:

LinkAnnotation

the annotation created on the destination page.

Copy a LinkAnnotation to the specified page. The annotation will be centered on the page. To center the annotation at a specific point, use the version of this method that accepts a Point.

This creates a copy of the original LinkAnnotation and puts the copy in the destination page's annotation dictionary. Structural content information associated with the source annotation will not be present in the copy. An exception will be thrown if the annotation cannot be copied to the specified page.

Note: If copying LinkAnnotations between pages in different documents, the source annotation may have a ViewDestination that's invalid in the destiantion document or an Action referring to a ViewDestination that's invalid in the destination document. In these cases, an exception will be thrown.

LinkAnnotation copyTo(Page destination, Point centerPoint)

Parameters

destination: Page: the page to copy the annotation to. The page may be in the same document as the source annotation or in a different document.
centerPoint: Point: the point to center the annotation on.

Returns:

LinkAnnotation

the annotation created on the destination page.

Copy a LinkAnnotation to the specified page and center the annotation on the specified point.

synchronized void

boolean equals(Object rhs)

Parameters

Returns:

void

Form generateAppearance()

Returns:

Form

A new Form containing the generated appearance, or null if the appearance could not be generated (for example, due to an invalid border style).

Generate a new appearance stream with the current annotation properties.

The resulting Form can then be used to set the annotation's appearance, such as by calling SetNormalAppearance.

Action getAction()

Returns:

Action

The Action object for this link.

Note that setting the Action will wipe out the Link's Destination member a link annotation cannot have both members.

double getAnnotationFeatureLevel()

Returns:

double

The minimum PDF version necessary to support the features used in this annotation.

String getBorderStyle()

Returns:

String

The border style.

Can be one of:
S - Solid

D - Dashed. The dash pattern is specified as an array (see DashPattern)

B - Beveled

I - Inset

U - Underline

Other border styles may be defined in the future. Default is "S"

java.util.List< Double > getBorderStyleDashPattern()

Returns:

java.util.List< Double >

An array defining a pattern of dashes and gaps to be used in drawing a dashed border (border style D).

The dash array is a series of numbers that specify the lengths of alternating dashes and gaps. Lengths must be nonnegative, and are expressed in user space units.

Default value is [3]

double getBorderStyleWidth()

Returns:

double

The border width in points.

If this value is 0, no border is drawn. The default is 1.0.

Color getColor()

Returns:

Color

The annotation's color.

The color of the annotation.

String getContents()

Returns:

String

The annotation's text contents.

The text contents of the annotation. The text to be displayed for the annotation or, if this type of annotation does not display text, an alternate description of the annotation's contents in human-readable form.

ViewDestination getDestination()

Returns:

ViewDestination

The Destination for this link.

Note that setting the Destination will wipe out the Link's Action member a link annotation cannot have both members.

java.util.EnumSet< AnnotationFlags > getFlags()

Returns:

java.util.EnumSet< AnnotationFlags >

The annotation's flags.

The flags for the annotation.

HighlightStyle getHighlight()

Returns:

HighlightStyle

The Highlighstyle for this link.

Color getInteriorColor()

Returns:

Color

The interior fill color, or null if no interior color is set.

The interior color with which to fill the annotation's rectangle or circle. The color of the border itself can be retrieved from Annotation.Color.

Form getNormalAppearance()

Returns:

Form

A Form representing the annotation's normal appearance, or null if no normal appearance has been set.

The normal appearance of the annotation, represented as a Form XObject.

double getOpacity()

Returns:

double

The opacity value for this annotation.

The constant opacity value used in painting a Markup annotation. Opacity is a range from 0.0 (fully transparent) to 1.0 (fully opaque).

OptionalContentMembershipDict getOptionalContentMembershipDict()

Returns:

OptionalContentMembershipDict

the OptionalContentMembershipDict

The OptionalContentMembershipDict property for this Annotation.

Setting this property will attach the Annotation to an OptionalContentMembershipDict; it will then be associated with the OptionalContentGroups and be subject to the VisibilityPolicy and VisibilityExpression of that MembershipDict.

By setting this property to null, the Annotation is detached from any OptionalContentMembershipDict.

PDFDict getPDFDict()

Returns:

PDFDict

The PDFDict associated with this annotation.

The underlying PDF dictionary for this annotation. Retrieves the PDFDict representation of this annotation object.

Rect getRect()

Returns:

Rect

The annotation's bounding rectangle in user space coordinates.

The size and location of the annotation on its page.

String getSubtype()

Returns:

String

The subtype string (e.g. "Circle", "Square", "Line").

The annotation's subtype.

String getTitle()

Returns:

String

The title string.

The title of the annotation.

boolean hasRichTextData()

Returns:

boolean

true if the annotation contains Rich Text String content.

Checks the annotation for Rich Text String content (PDFReference 1.7 Section 8.6.2). Annotations that contain Rich Text String content and do not have a normal appearance set will not be visible when rendering the page.

boolean isCurrentlyVisible(OptionalContentContext occ)

Parameters

occ: OptionalContentContext: The optional content context in which to check visibility.

Returns:

boolean

true if the annotation is currently visible.

Tests whether an annotation is visible in a given optional content context, considering the current ON-OFF states of the optional-content groups in the optional-content dictionary (OCMD) and the dictionary's visibility policy.

If the annotation occurs more than once within the content, this method only checks the visibility of the first occurrence of the annotation.

This method determines visibility without considering the visbility of the Content object that the annotation belongs to. To determine the visibility of an annotation while taking the Content's visibility into consideration, use the alternate version of this method.
