Class PolyLine
Polyline annotations (PDF 1.5) display (open or closed) shapes of multiple edges on the page. Such polylines may have any number of vertices connected by straight lines. For open polylines, which is the default type of polylines, the first and last vertex are not implicitly connected. Closed polylines are polygons, whose first and last vertex are connected.

Syntax
public class PolyLine : Line, IDisposableConstructors
PolyLine(Annot)
Creates a PolyLine annotation and initialize it using given annotation object.
Declaration
public PolyLine(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 |
PolyLine(Obj)
Creates a PolyLine annotation and initialize it using given Cos/SDF object.
Declaration
public PolyLine(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 PolyLine annotation, in the specified document.
Declaration
public static PolyLine Create(SDFDoc doc, Rect pos)Parameters
| Type | Name | Description |
|---|---|---|
| SDFDoc | doc | A document to which the PolyLine annotation is added. |
| Rect | pos | A rectangle specifying the PolyLine annotation's bounds, specified in user space coordinates. |
Returns
| Type | Description |
|---|---|
| PolyLine | A newly created blank PolyLine annotation. |
Exceptions
| Type | Condition |
|---|---|
| PDFNetException | PDFNetException the PDFNet exception |
