The Rect type exposes the following members.

	Name	Description
	Rect(Point2D, Size2D)	Constructor for Cvb rectangles.
	Rect(Int32, Int32, Int32, Int32)	Constructor for Cvb rectangles.

	Name	Description
	Area	Area of the rectangle.
	Bottom	Bottom row of the rectangle (still inside the rectangle).
	CoordinateSystem	Indicates the coordinate system in which this object is being measured (when used as an area of interest).
	Height	Height of the rectangle.
	IsEmpty	True if width and height are both zero, false otherwise.
	Left	First column of the rectangle.
	Location	Location of the top left corner of the rectangle.
	Right	Rightmost column of the rectangle (still inside the rectangle).
	Size	Size of the rectangle.
	Top	First row of the rectangle.
	Width	Width of the rectangle.

	Name	Description
	Ceiling	Converts the given rect to a Rect structure by rounding the values of the RectD structure to the next higher integer number.
	Contains(Point2D)	Check if a point is located inside this Rect.
	Contains(Point2Dd)	Check if a point is located inside this Rect.
	Contains(Int32, Int32)	Determines if the specified point is contained with this Rect.
	Contains(Point2Dd, Double)	Check if a point is located inside this Rect.
	CropExtent	Assuming that a Rect structure contains the extent of something relative to a position inside an image, this function crops the Rect so that the whole content is inside the image.
	Equals	Tests whether obj is a Rect structure with the same/ location and size as this Rect structure. (Overrides ValueTypeEquals(Object).)
	FromLTRB	Creates a Rect structure with the specified edge locations.
	GetHashCode	Returns the hash code for this Rect. (Overrides ValueTypeGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Intersect(Rect)	Replaces this rectangle with the intersection of itself and the specified rectangle.
	Intersect(Rect, Rect)	Returns a Rect structure that represents the intersection of the two input rectangles. If there is no intersection, an empty Rect is returned.
	IntersectsWith	Test if this rectangle intersects with rect.
	Round	Converts the given rect to a Rect structure by rounding the values of the RectD structure mathematically.
	ToString	String conversion. (Overrides ValueTypeToString.)
	Truncate	Converts the given rect to a Rect structure by rounding the values of the RectD structure to the next lower integer number.
	TruncateCeiling	Converts the given rect to a Rect structure by truncating Left and Top and rounding Right and Bottom to the next higher integer number.
	Union	Gets a Rect structure that contains the union of two Rect structures.

	Name	Description
	Equality	Comparison operator for Rect structures.
	(RectD to Rect)	Explicit conversion operator (truncates the values).
	Inequality	Comparison operator for Rect structures.

	Name	Description
	Empty	Null-element.

	Name	Description
	Contains	Check if a point is located inside this Rect. (Defined by RectExtensions.)
	ToRectangle	Convert a Rect to a Rectangle. (Defined by ImageExtensions.)
	ToWindowsRect	Creates a Rect from this rectangle. (Defined by RectExtensions.)

Unlike System.Drawing.Rectangle, which upholds the convention that Right and Bottom are not part of the rectangle (in other words: Width = Left - Right and Height = Bottom - Top), Common Vision Blox always uses rectangles (or rectangular shaped areas of interest represented by integer parameters left, top, right and bottom) in such a way that right and bottom are still part of the area to be investigated (i.e. Width = Right - Left + 1 and Height = Bottom - Top + 1).

To model this difference correctly we decided to give CVB.Net a rectangle of its own which behaves according to the conventions used in Common Vision Blox.
