AppearanceSet Class

Pdf annotations support appearances that can be associated with three interaction modes NormalHow the annotation will appear under typical circumstances (ie, no interaction)RolloverHow the annotation will appear when the cursor is in the annotationActivatedHow the annotation will appear when click on Each of this modes is associated with a collection of appearances, each of which corresponds to an annotation's current state. For example, a CheckboxWidgetAnnotation defines states for when it has been checked and when it is clear. The Normal property would contain appearances for each of these states. When an annotation only has one state, the name of that state is inconsequetial and will be ignored when written to the PDF file. For naming purposes, if an annotation has only a single state with no meaningful name, you can use DefaultAppearanceName for the name.

RectangleAnnotation anno = new RectangleAnnotation(new PdfBounds(72, 400, 200, 200));
DrawingTemplate template = new DrawingTemplate(new PdfBounds(0, 0, anno.Bounds.Width, anno.Bounds.Height));
PdfPath path = new PdfPath(PdfColorFactory.FromRgb(.8, .25, .25));
path.FillMethod = PdfFillMethod.NonZeroWinding;
path.MoveTo(100, 200);
