Syntax

public class Link : Annot, IDisposable

Constructors

Link(Annot)

Creates a Link annotation and initialize it using given annotation object.

Declaration

public Link(Annot ann)

Parameters

Type	Name	Description
Annot	ann	the annot

Remarks

The constructor does not copy any data, but is instead the logical equivalent of a type cast.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

Link(Obj)

Creates a Link annotation and initialize it using given Cos/SDF object.

Declaration

public Link(Obj d)

Parameters

Type	Name	Description
Obj	d	the d

Remarks

The constructor does not copy any data, but is instead the logical equivalent of a type cast.

Methods

Create(SDFDoc, Rect)

Creates a new Link annotation.

Declaration

public static Link Create(SDFDoc doc, Rect pos)

Parameters

Type	Name	Description
SDFDoc	doc	A document to which the annotation is added.
Rect	pos	A rectangle specifying the annotation's bounds, specified in user space coordinates.

Returns

Type	Description
Link	A new Link annotation.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

Create(SDFDoc, Rect, Action)

Creates a new Link annotation.

Declaration

public static Link Create(SDFDoc doc, Rect pos, Action action)

Parameters

Type	Name	Description
SDFDoc	doc	A document to which the annotation is added.
Rect	pos	A rectangle specifying the annotation's bounds, specified in user space coordinates.
Action	action	Action for the link annotation.

Returns

Type	Description
Link	A new Link annotation.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

~Link()

Releases all resources used by the Link

Declaration

protected ~Link()

GetAction()

Gets the Action of the Linked Annotation.

Declaration

public Action GetAction()

Returns

Type	Description
Action	An Action object that denotes the action of the linked annotation.

Remarks

The return value is an action that shall be performed when the link annotation is activated

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

GetHighlightingMode()

Gets the HighlightingMode Linked Annotation.

Declaration

public Link.HighlightingMode GetHighlightingMode()

Returns

Type	Description
Link.HighlightingMode	The HighLighting mode represented as an entry of the enum "HighlightingMode".

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

GetQuadPoint(int)

Gets the QuadPoint located at a certain index of the QuadPoint array of the Link annotation.

Declaration

public QuadPoint GetQuadPoint(int idx)

Parameters

Type	Name	Description
int	idx	the idx

Returns

Type	Description
QuadPoint	The QuadPoint located at a certain index of the QuadPoint array of the Link annotation.

Remarks

An array of n QuadPoints specifying the coordinates of n quadrilaterals in default user space that comprise the region in which the link should be activated. The coordinates specifying the four vertices of the quadrilateral in counterclockwise order. For orientation purposes, such as when applying an underline border style, the bottom of a quadrilateral is the line formed by p1 and p2 of the QuadPoint. QuadPoints shall be ignored if any coordinate in the array lies outside the region specified by Rect.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

GetQuadPointCount()

Gets the number of QuadPoints in the QuadPoints array of the Link annotation.

Declaration

public int GetQuadPointCount()

Returns

Type	Description
int	The number of QuadPoints.

Remarks

An array of n QuadPoints specifying the coordinates of n quadrilaterals in default user space that comprise the region in which the link should be activated. The coordinates specifying the four vertices of the quadrilateral in counterclockwise order. For orientation purposes, such as when applying an underline border style, the bottom of a quadrilateral is the line formed by p1 and p2 of the QuadPoint. QuadPoints shall be ignored if any coordinate in the array lies outside the region specified by Rect.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

RemoveAction()
