Hello Gunther,

Do you want to draw annotation using mouse or programmatically?

Hello Gunther,

Here is a code snippet that shows how to create lines annotation programmatically: 
// create lines annotation
LinesAnnotationData linesAnnoData = new LinesAnnotationData();
// specify points of lines annotation
linesAnnoData.Points.Add(new PointF(0, 0));
linesAnnoData.Points.Add(new PointF(500, 500));

// create view of lines annotation
LinesAnnotationView linesAnnoView = new LinesAnnotationView(linesAnnoData);

// get reference to annotation view collection of first image
AnnotationViewCollection annoViews = annotationViewer1.AnnotationViewController[0];
// add lines annotation view to annotation view collection of first image
annoViews.Add(linesAnnoView);
Best regards, Alexander
