Example

For a complete example on how to use annotation draw and edit designers, refer to AnnDesigner.

This example initializes a new designer to draw text objects.

Imports Leadtools.Windows.Controls 
Imports Leadtools.Windows.Annotations 
 
Public Function AnnTextDrawDesigner_AnnTextDrawDesigner(ByVal viewer As ImageViewer, ByVal container As AnnContainer) As AnnTextDrawDesigner 
   ' start a new text draw designer 
   Dim textDrawDesigner As AnnTextDrawDesigner = New AnnTextDrawDesigner(container) 
   ' set up the object template (the text object) 
   Dim textObject As AnnTextObject = New AnnTextObject() 
   textObject.Stroke = Nothing 
   textObject.Fill = Nothing 
   textObject.FontFamilyName = "Arial" 
   textObject.FontSize = 10.0 
   textObject.TextEdgeMargin = 0.0 
   textObject.TextHorizontalAlignment = AnnTextAlignment.Center 
   textObject.TextVerticalAlignment = AnnTextAlignment.Center 
 
   ' set up the default text to be used 
   textDrawDesigner.DefaultText = "Leadtools" 
 
   ' initialize the rest of the designer 
   textDrawDesigner.ObjectTemplate = textObject 
 
   Return textDrawDesigner 
End Function
