Region (PDFxStream API Reference)

All Superinterfaces:

Bounded

All Known Implementing Classes:

Rectangle
```
public interface Region
extends Bounded
```
Instances of Region represent a rectangluar space.
All of the functions provided by Region are in units 1/72" apiece. So, an 8.5" x 11" page will have a width and height of 612 and 792, respectively, with the origin of a graphical context positioned in the bottom-left corner.

The point described by the values returned by the lx() and by() function is guaranteed to be the bottom-left point of the rectangle. The values returned by the rx() and ty() functions form the top-right point of the rectangle.

A Region rooted at the point (100, 100) with width of 200 units and height of 300 units will return the following values:
```
 lx() = 100
 rx() = 300
 by() = 100
 ty() = 400
 height() = 300
 width() = 200
 
```
