Class Overview
Rect is a utility class used to manipulate PDF rectangle objects (refer to section 3.8.3 of the PDF Reference Manual). Rect can be associated with a SDF/Cos rectangle array using Rect(Obj*) constructor or later using Rect::Attach(Obj*) or Rect::Update(Obj*) methods. Rect keeps a local cache for rectangle points so it is necessary to call Rect::Update() method if the changes to the Rect should be saved in the attached Cos/SDF array.
Note: - Although rectangles are conventionally specified by their lower-left and upperright corners, it is acceptable to specify any two diagonally opposite corners.

| y | y coordinate of the point |
Returns
- true is the point is in the rectangle, false otherwise.
Throws
| PDFNetException |
|---|
public void destroy ()
Frees the native memory of the object. This can be explicitly called to control the deallocation of native memory and avoid situations where the garbage collector does not free the object in a timely manner.
