Represents an annotation feature in an
AnnotationFeatureClass.
Rotate or Move the Annotation
await QueuedTask.Run(() =>
{
//Don't use 'Shape'....Shape is the bounding box of the annotation text. This is NOT what you want...
//
//var insp = new Inspector();
//insp.Load(annoLayer, oid);
//var shape = insp["SHAPE"] as Polygon;
//...wrong shape...
//Instead, we must get the TextGraphic from the anno feature.
//The TextGraphic shape will be the anno baseline...
//At 2.1 the only way to retrieve this textLine is to obtain the TextGraphic from the AnnotationFeature
QueryFilter qf = new QueryFilter()
{
WhereClause = "OBJECTID = 1"
};
//annoLayer is ~your~ Annotation layer
using (var rowCursor = annoLayer.Search(qf))

});
Get the Annotation Text Graphic
await QueuedTask.Run(() =>
{
using (var table = annoLayer.GetTable())
{
using (var rc = table.Search())
{
rc.MoveNext();
using (var af = rc.Current as AnnotationFeature)
{
var graphic = af.GetGraphic();
var textGraphic = graphic as CIMTextGraphic;
//Note:
//var outline_geom = af.GetGraphicOutline();
//gets the anno text outline geometry...
}
}
}
});
Get the Outline Geometry for an Annotation
var annoLayer = MapView.Active.Map.GetLayersAsFlattenedList()
.OfType<AnnotationLayer>().FirstOrDefault();
if (annoLayer == null)
return;
QueuedTask.Run(() =>
{
//get the first annotation feature...
//...assuming at least one feature gets selected
using (var fc = annoLayer.GetFeatureClass())
{
using (var rc = fc.Search())
{
rc.MoveNext();
using (var af = rc.Current as AnnotationFeature)
{
var outline_geom = af.GetGraphicOutline();
//TODO - use the outline...
//Note:
//var graphic = annoFeature.GetGraphic();
//gets the CIMTextGraphic...
}
}
}
