class AnnContainer:
The annotation container is a rectangular area that holds related annotation objects (AnnObject). In typical applications, the container holds the annotation objects for a page in a document. The size of the container is the same as the page but in annotation units (1/720 of an inch).
AnnContainer contains the following members:
Member | Description |
---|---|
Size, Offset and PageNumber |
Properties of the container: Size is the size of the container in annotation units (1/720 of an inch). Offset is an optional offset value (if the container does not start at 0,0) and PageNumber is the optional 1-based page number of the container |
The object responsible for converting display, container and image coordinates |
|
A collection of AnnObjects. These are the annotation objects that belong in this container. These objects will be rendered when the container is rendered and edited when the container is automated |
|
Special annotation object that is responsible for maintaining a list of the objects that are currently selected in the container |
|
A collection of AnnLayers used to logically group common annotation objects. |
|
Helper method used to perform hit-testing on the container and return any object under a test point or rectangle |
|
Optional values used when rendering this container: Whether it is visible and the border stroke and interior filling options |
|
Optional value indicating whether this container is enabled. If a container is disabled, then it will be used by the automation and considered read-only. |
|
Optional labels that can be used to overlay fixed text on top of the container, such as map legends |
|
Method to easily resize a container to a desired size. Has various options |
This example creates a new container, adds a line and a rectangle object to it, saves it and then loads it back.
