The SbBox2s class is a 2 dimensional box with short integer coordinates.
This box class is used by other classes in Coin for data exchange. It provides storage for two box corners with short integer coordinates, which is among other things useful for representing screen or canvas areas in absolute window coordinates.
|
inline |
The default constructor makes an empty box.
|
inline |
Constructs a box with the given corner coordinates.
xmin should be less than xmax and ymin should be less than ymax if you want to make a valid box.
Constructs a box with the given corners.
The coordinates of min should be less than the coordinates of max if you want to make a valid box.

Reset the boundaries of the box.
xmin should be less than xmax and ymin should be less than ymax if you want to make a valid box.
Returns reference to self.
Reset the boundaries of the box with the given corners.
The coordinates of min should be less than the coordinates of max if you want to make a valid box.
Returns reference to self.
Reset the boundaries with the boundaries of the given box.
Returns reference to self.
Reset the boundaries with the boundaries of the given box.
Returns reference to self.
Reset the boundaries with the boundaries of the given box.
Returns reference to self.
|
inline |
Returns the box boundary coordinates.
Returns the box corner points.
|
inline |
Returns the minimum point. This should usually be the lower left corner point of the box.
|
inline |
Returns the lower left corner of the box.
|
inline |
Returns the maximum point. This should usually be the upper right corner point of the box.
|
inline |
Returns the upper right corner of the box.
void SbBox2s::extendBy | ( | const SbVec2s & | point | ) |
Extend the boundaries of the box by the given point, i.e. make the point fit inside the box if it isn't already within it.
void SbBox2s::extendBy | ( | const SbBox2s & | box | ) |
Extend the boundaries of the box by the given box parameter. This is equal to calling extendBy() twice with the corner points.
void SbBox2s::makeEmpty | ( | void | ) |
Marks this as an empty box.
|
inline |
Check if this has been marked as an empty box.
|
inline |
Check if the box has been correctly specified and by that virtue has "positive" area, i.e. all coordinates of its upper right corner (the maximum point) are greater than the corresponding coordinates of its lower left corner (the minimum point).
Check if the given point lies within the boundaries of this box.
Check if box lies entirely or partially within the boundaries of this box.
|
inline |
Returns the center point of the box.
|
inline |
Returns the coordinates of the box origin (i.e. the lower left corner).
|
inline |
Returns width and height of box.
|
inline |
Returns width and height of box as a 2D vector.
|
inline |
Returns aspect ratio of box, which is defined as box width divided on box height.
