When creating LEADTOOLS Annotations objects, some users may which to change the default annotations settings such as Color, Fill, Stroke-width etc. By using the AnnAutomationObjects ObjectTemplate property, users can change the default properties of a specific object whenever an instance is created.

Within your project, after creating the default automation objects, you can use the AutomationManagers FindObjectById method to edit the particular annotation object that you want. In this case, we're editing the AnnRectangleObject. Afterwards, you can use the ObjectTemplate property and cast the object into your AnnObject to edit it's particular settings such as Fill and Stroke.

Code:

AnnAutomationObject customAnn = _automationManager.FindObjectById(AnnObject.RectangleObjectId);
AnnRectangleObject customRect = (AnnRectangleObject)customAnn.ObjectTemplate;
customRect.Fill = null;
customRect.Stroke = AnnStroke.Create(AnnSolidColorBrush.Create("Blue"), LeadLengthD.Create(50));

From these steps, we have edited the default standard AnnRectangleObject from having a thin red border to having a default AnnRectangleObject with a thick blue border whenever an instance is created.
