VisualizationFoundation CAT2DBoundingBox
Usage: you must use this class as is. You should never derive it.
public class CAT2DBoundingBox
Class to manage a box encompassing 2D elements.
Role:This classe is used to manage the space used by a 2D
element. This information is used at the rendering time to know if a given
element is visible on the screen and needs to be drawn on not.
For performances issues 2DBoundingBox need to be at close to the object they are linked
to as possible. Idealy they represent the smallest rectangle containing the object.
You can add 2 2DBoundingBox using the += operator.

Constructor and Destructor
o CAT2DBoundingBox
| public CAT2DBoundingBox( | ) |
-
Default constructor.
Construct a boundingBox of width and height 1 and centered on 0,0.
o CAT2DBoundingBox
| public CAT2DBoundingBox( | const | x, |
| const | y, |
| const | size_mm) |
-
Construct a Box of width and height 0 and 0 and centered in x,y.
This is used for non zoomable objects.
- Parameters:
-
- x
- The x value of the center
- y
- The y value of the center
- size_mm
- The size of the non zommable box (it is a square in this case)
o CAT2DBoundingBox
| public CAT2DBoundingBox( | const | ) |
-
Copy Constructor
o CAT2DBoundingBox
| public CAT2DBoundingBox( | const | xmin, |
| const | xmax, |
| const | ymin, |
| const | ymax) |
-
Construct a 2DBoundingBox.
- Parameters:
-
- xmin
- The min x value
- xmax
- The max x value
- ymin
- The min y value
- ymax
- The max y value
o CAT2DBoundingBox
| public CAT2DBoundingBox( | const | bs) |
-
Creates a BoundingBox from a 2DBoundingSphere.
You get the smallest Box containing the circle.
- Parameters:
-
- bs
- The 2DboundingSphere tou construct the box from.
o ~CAT2DBoundingBox
| public virtual ~CAT2DBoundingBox( | ) |
-
Methods
o GetCenter
-
Returns the Bounding Box center.
- Returns:
- The 2DBoundingBox center.
o GetParameter
| public GetParameter( | | xmin, |
| | xmax, |
| | ymin, |
| | ymax) |
-
Retrieves the BoundingBox parameters.
- Parameters:
-
- xmin
- The returned xmin.
- xmax
- The returned xmax
- ymin
- The returned ymin
- ymax
- The returned ymax.
o GetSizeMM
-
Returns the 2DBoundingBox size in milimmeters.
- Returns:
- The size in mm of the 2DBoundingBox.
A non zero value means the object this box is attached too will have that
size on the screen whatever the zoom value is.
o operator *=
| public operator *=( | const | iMatrix) |
-
Multiplication assignment operator.
- Parameters:
-
- iMatrix
- The tranform to apply to the boundingbox.
- Returns:
- The 2DBoundingBox resulting from this transformation.
o operator +=
| public operator +=( | const | bbox) |
-
Addition assignment operator.
- Parameters:
-
- bbox
- The boundingbox to add.
- Returns:
- The 2DBoundingBox resulting from this transformation
o operator =
| public operator =( | const | bbox) |
-
Assignment operator.
- Parameters:
-
- bbox
- The 2DBoundingBox to assign to the current one.
- Returns:
- The 2DBoundingBox resulting from the assignment.
