GetAnnotRectEx
Annotations and hotspot links
Description
Reads the bounding rectangle of an annotation and returns it decomposed into Left, Top, Width and Height in page units
The corner coordinates of the raw /Rect array are normalized during extraction, so Width and Height never come back negative. The values follow the coordinate origin configured for the document and match the arguments accepted by SetAnnotRect
