Jason Nelson	95f0459900	Prefer is null to == null ... ensures that an equals overload isn't use, and we don't compare structs	2024-03-16 12:37:51 +00:00
Eliot Jones	00bd285262	add support for quadpoints to annotations ... highlight, link, strikeout, squiggly and underline annotation types may define a set of quadrilaterals using the quadpoints entry. this defines the regions to show/activate the annotation. the order of points in the quadpoints array does not match the specification so we provide a convenience class to access the point data rather than interpreting it as a rectangle: https://stackoverflow.com/questions/9855814/pdf-spec-vs-acrobat-creation-quadpoints.	2020-01-05 16:23:07 +00:00
