Annotation

Detailed Description

A circle annotation is an annotation surrounded by a curved and possibly elliptical border. The circle is inscribed within the annotation rectangle. Despite the circle name, the width and height of the annotation rectangle need not be equal. So the circle can actually be an ellipse.

Constructor & Destructor Documentation

CircleAnnotation

CircleAnnotation(Pagepage, RectinitialRect)

Parameters

page: Page

The page to which the CircleAnnotation is added.

initialRect: Rect

A rectangle specifying the annotation's bounds, specified in user space coordinates.

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

CircleAnnotation

CircleAnnotation(Pagepage, RectinitialRect, intaddAfter)

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.

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

Returns:

A Form representing the visual appearance of this annotation, or null if the appearance could not be generated (e.g. due to an invalid border style).

Generate a new appearance stream for this circle annotation. Creates an appearance based on the current annotation properties, including color, interior color, border style, and bounding rectangle. The circle (or ellipse) is inscribed within the annotation rectangle.

getAnnotationFeatureLevel

doublegetAnnotationFeatureLevel()

Returns:

The minimum PDF version level (e.g. 1.3, 1.4, or 1.5).

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

getBorderStyle

String

The border style.

Can be one of:
S - Solid

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

getBorderStyleDashPattern

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]

getBorderStyleWidth

doublegetBorderStyleWidth()

Returns:

double

The border width in points.

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

getColor

ColorgetColor()

Returns:

The annotation's color.

The color of the annotation.

getContents

StringgetContents()

Returns:

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.

getFlags

java.util.EnumSet< AnnotationFlags >getFlags()

Returns:

The annotation's flags.

The flags for the annotation.

getInteriorColor

ColorgetInteriorColor()

Returns:

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.

getNormalAppearance

Returns:

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.

getOpacity

doublegetOpacity()

Returns:

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).

getOptionalContentMembershipDict

OptionalContentMembershipDictgetOptionalContentMembershipDict()

Returns:

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.

getPDFDict

PDFDictgetPDFDict()

Returns:

The PDFDict associated with this annotation.

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

getRect

RectgetRect()

Returns:

The annotation's bounding rectangle in user space coordinates.

The size and location of the annotation on its page.

getSubtype

StringgetSubtype()

Returns:

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

The annotation's subtype.

getTitle

StringgetTitle()

Returns:

The title string.

The title of the annotation.

hasRichTextData

booleanhasRichTextData()

Returns:

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.

isCurrentlyVisible

booleanisCurrentlyVisible(OptionalContentContextocc)

Parameters

occ: OptionalContentContext

The optional content context in which to check visibility.

Returns:

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.
