public interface Region extends Bounded
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 Region.lx() and Region.by()
function is guaranteed to be the bottom-left point of the rectangle. The values returned by the
Region.rx() and Region.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
