I'm trying to add a custom annotation (i.e. with a custom appearance stream that defines exactly what I want to show) to a page. I'm confused on which PDAnnotation class to use and I can't find anything related in the spec. I've used RubberStamp and SquareCircle (as "Square") and I get to see what I want but, to add to my confusion, any kind of edit from within Acrobat Reader destroys the rendering of the annotation (turns it to a box with an X joining the corners). What's going on?
