Property Value

A collection of AnnLabels to render on top of this AnnContainer.

Remarks

The labels will be rendered using the global AnnRenderingEngine.ContainerLabelRenderer object. This object is automatically created by the annotation framework and can be usable right away.

The container labels can be used to place text items on top of the container that are not part of the annotations objects. For example, to place legends in a mapping application.

Example

using Leadtools.Annotations.Automation; 
using Leadtools.Annotations.Engine; 
using Leadtools.Codecs; 
using Leadtools.Annotations.WinForms; 
 
public void AnnContainer_Labels() 
{ 
   // Get the container for this automation 
   AnnContainer container = _automation.Container; 
 
   double inch = 720.0; 
 
   // Create a couple of labels 
   AnnLabel label = new AnnLabel(); 
   label.IsVisible = true; 
   label.OriginalPosition = LeadPointD.Create(1 * inch, 1 * inch); 
   label.Foreground = AnnSolidColorBrush.Create("Red"); 
   label.Background = AnnSolidColorBrush.Create("rgba(0, 0, 0, 0.5)"); 
   label.Text = "Red Label"; 
   container.Labels.Add(label); 
 
   label = new AnnLabel(); 
   label.IsVisible = true; 
   label.OriginalPosition = LeadPointD.Create(4 * inch, 4 * inch); 
   label.Foreground = AnnSolidColorBrush.Create("Blue"); 
   label.Background = AnnSolidColorBrush.Create("rgba(0, 0, 0, 0.5)"); 
   label.Text = "Blue Label"; 
   container.Labels.Add(label); 
 
   // Show the labels 
   _automation.Invalidate(LeadRectD.Empty); 
}
