Annotation

Detailed Description

A polygon is a closed plane figure bounded by a finite number of line segments. In this case the polygon is created as an annotation added to a PDF file.

Constructor & Destructor Documentation

PolygonAnnotation

PolygonAnnotation(Pagepage, RectinitialRect, java.util.List< Point >vertices)

Parameters

page: Page

The page to which the PolygonAnnotation is added.

initialRect: Rect

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

vertices: java.util.List< Point >

A list of points representing the coordinates of the vertices, specified in user space.

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

PolygonAnnotation

PolygonAnnotation(Pagepage, RectinitialRect, java.util.List< Point >vertices, 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.

vertices: java.util.List< Point >

A list of points representing the coordinates of the vertices, specified in user space.

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 PolygonAnnotation at a specific index in the page's annotation array.

[static initializer]

static void[static initializer]()

delete

synchronized voiddelete(Booleandisposing)

Parameters

disposing: Boolean

booleanequals(Objectrhs)

Parameters

rhs: Object

Returns:

boolean

finalize

voidfinalize()

Returns:

void

generateAppearance

FormgenerateAppearance()

Returns:

Form

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.

getAnnotationFeatureLevel

doublegetAnnotationFeatureLevel()

Returns:

double

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

getBorderStyle

StringgetBorderStyle()

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"

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:

Color

The color of the annotation.

getContents

StringgetContents()

Returns:

String

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:

java.util.EnumSet< AnnotationFlags >

The flags for the annotation.

getInteriorColor

ColorgetInteriorColor()

Returns:

Color

The interior color with which to fill the annotation's line endings.

The color of the line itself can be retrieved from Annotation.Color.

getNormalAppearance

FormgetNormalAppearance()

Returns:

Form

getOpacity

doublegetOpacity()

Returns:

double

The optional constant opacity value that shall be 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:

PDFDict

Retrieve the PDFObject representation of this object

getRect

RectgetRect()

Returns:

Rect

The size and location of the annotation on its page

getSubtype

StringgetSubtype()

Returns:

String

The annotation's subtype

getTitle

StringgetTitle()

Returns:

String

The title of the annotation.

getVertices

java.util.List< Point >getVertices()

Returns:

The array of points, in order, that define the vertices of the polygon in user space coordinates.

hasRichTextData

booleanhasRichTextData()

Returns:

boolean

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

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.
