In this case the polygon is created as an annotation added to a PDF file. **Uses types:** [`Annotation`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Annotation.md), [`Color`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Color.md), [`Form`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Form.md), [`OptionalContentContext`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/OptionalContentContext.md), [`OptionalContentMembershipDict`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/OptionalContentMembershipDict.md), [`PDFDict`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/PDFDict.md), [`Page`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Page.md), [`Point`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Point.md), [`Rect`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Rect.md) ## Constructors ### PolygonAnnotation ```java com.datalogics.PDFL.PolygonAnnotation.PolygonAnnotation(Page page, Rect initialRect, java.util.List< Point > vertices) ``` *constructor* **Parameters** - `page` ([`Page`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Page.md)): The page to which the PolygonAnnotation is added. - `initialRect` ([`Rect`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Rect.md)): A rectangle specifying the annotation's bounds, specified in user space coordinates. - `vertices` ([`java.util.List< Point >`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Point.md)): 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 ```java com.datalogics.PDFL.PolygonAnnotation.PolygonAnnotation(Page page, Rect initialRect, java.util.List< Point > vertices, int addAfter) ``` *constructor* **Parameters** - `page` ([`Page`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Page.md)): The page to which the annotation is added. - `initialRect` ([`Rect`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Rect.md)): A rectangle specifying the annotation's bounds, specified in user space coordinates. - `vertices` ([`java.util.List< Point >`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Point.md)): 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. ## Methods ### delete ```java synchronized void com.datalogics.PDFL.PolygonAnnotation.delete(Boolean disposing) ``` *protected* **Parameters** - `disposing` (`Boolean`) **Returns:** `synchronized void` ### delete ```java synchronized void com.datalogics.PDFL.PolygonAnnotation.delete() ``` **Returns:** `synchronized void` ### equals ```java boolean com.datalogics.PDFL.Annotation.equals(Object rhs) ``` **Parameters** - `rhs` (`Object`) **Returns:** `boolean` ### finalize ```java void com.datalogics.PDFL.PolygonAnnotation.finalize() ``` *protected* **Returns:** `void` ### generateAppearance ```java Form com.datalogics.PDFL.PolygonAnnotation.generateAppearance() ``` **Returns:** [`Form`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Form.md) A new Form representing the visual appearance of the polygon, or NULL if the appearance could not be generated (for example, due to an invalid border style).

The vertices that define the polygon annotation, in user space. ### hasRichTextData ```java boolean com.datalogics.PDFL.Annotation.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. ### isCurrentlyVisible ```java boolean com.datalogics.PDFL.Annotation.isCurrentlyVisible(OptionalContentContext occ) ``` **Parameters** - `occ` ([`OptionalContentContext`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/OptionalContentContext.md)): 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. ### setAnnotationFeatureLevel ```java void com.datalogics.PDFL.PolygonAnnotation.setAnnotationFeatureLevel(double featureLevel) ``` **Parameters** - `featureLevel` (`double`) **Returns:** `void` Removes features not supported in the supplied version number. ### setBorderStyle ```java void com.datalogics.PDFL.PolygonAnnotation.setBorderStyle(String style) ``` **Parameters** - `style` (`String`) **Returns:** `void` The border style.
