Container Annotation Object

Note:

This topic is for Document/Medical only.

The container annotation object (ANNOBJECT_CONTAINER) is a rectangle that is normally transparent, with a NULL line style. With the automated functions, its only purpose is to group other objects, including other container objects.

The class for Container Annotation objects is LAnnContainer.

With low-level functions, you can insert and remove objects from a container, and you must specify the coordinates of an object relative to the container that it is in. The outermost (root) container establishes the frame of reference for all other objects, as explained in Low-Level Coordinate System for Annotations.

With low-level functions, you must specify the defining rectangle. Other applicable properties for the container have the following defaults, which you can change:

Visible	Defaults to FALSE. It can be changed using LAnnotation::SetVisible.
Selected	Defaults to FALSE. It can be changed using LAnnotation::SetSelected.
Foreground color	Defaults to black. It can be changed using LAnnContainer::SetForeColor.
Background color	Defaults to white. It can be changed using LAnnContainer::SetBackColor.
Line width	Defaults to 1. It can be changed using LAnnContainer::SetLineWidth. (Values equate to a minimum of 1 pixel when displayed.)
Line style	Defaults to NULL. It can be changed using LAnnContainer::SetLineStyle.
Fill pattern	Defaults to solid. It can be changed using LAnnContainer::SetFillPattern.
Fill mode	Defaults to transparent. It can be changed using LAnnContainer::SetFillMode.
Text Displayed*	Defaults to Show text. It can be changed using LAnnotation::SetTextOptions.
Text Color*	Defaults to red (RGB(255,0,0). It can be changed using LAnnotation::SetTextOptions.
Tag (identifier)	Defaults to 0. It can be changed using LAnnotation::SetTag.
Window handle	Defaults to NULL or the handle inherited from the container.
User mode	Defaults to design mode or the mode inherited from the container.
Fixed State	Defaults to not fixed. It can be changed using LAnnXXX::SetFixed.
Name	Defaults to an empty string. It can be changed using the LAnnotation::SetNameOptions function.

* Note that in version 14.5, these features must be enabled using the LAnnotation::SetOptions function.

Use the LAnnotation::SetOptions function and the LAnnotation::GetOptions function to control the following features:

$image\sqrblit.gif$ Alpha Background Fill Option

$image\sqrblit.gif$ Annotation Rotate Option

$image\sqrblit.gif$ ESC to Cancel

$image\sqrblit.gif$ Calibrate Ruler Feature

For more information about these features, refer to New Annotation Features of Version 14.5.

If the annotation objects are container, automation, text, text pointer, stamp, note, pushpin, or button objects it is possible to use the LAnnotation::GetTextOptions and the LAnnotation::SetTextOptions functions to set the objects to show or hide the text and to set the color of the text. In addition, if the annotation objects are text or stamp objects these functions can set the objects to show or hide the borders of the object. In version 14.5, note that these features must be enabled using the LAnnotation::SetOptions function.

Use the LAnnotation::SetFillMode and LAnnotation::GetFillMode functions to manage the fill mode used by annotation objects. The LAnnotation::SetFillModeExt and the LAnnotation::GetFillModeExt extends the original functions to support the ANNMODE_ALPHA fill mode. Before calling these two functions, enable the alpha background fill mode by calling the LAnnotation::SetOptions function.
