NAME
SbBox2s -
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.

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

Constructor & Destructor Documentation
SbBox2s::SbBox2s (void) [inline] The default constructor makes an empty
box.
SbBox2s::SbBox2s (short xmin, short ymin, short xmax, short ymax) [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.
SbBox2s::SbBox2s (const SbVec2s & boxmin, const SbVec2s & boxmax) [inline]
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.
Member Function Documentation
SbBox2s & SbBox2s::setBounds (short xmin, short ymin, short xmax, short
ymax) [inline] 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.
See also:
getBounds().
SbBox2s & SbBox2s::setBounds (const SbVec2s & boxmin, const SbVec2s &
boxmax) [inline] 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.
See also:
getBounds().
SbBox2s & SbBox2s::setBounds (const SbBox2i32 & box) Reset the boundaries
with the boundaries of the given box.
Returns reference to self.
See also:
setBounds()
SbBox2s & SbBox2s::setBounds (const SbBox2f & box) Reset the boundaries
with the boundaries of the given box.
Returns reference to self.
See also:
setBounds()
SbBox2s & SbBox2s::setBounds (const SbBox2d & box) Reset the boundaries
with the boundaries of the given box.
Returns reference to self.
See also:
setBounds()
void SbBox2s::getBounds (short & xmin, short & ymin, short & xmax, short &
ymax) const [inline] Returns the box boundary coordinates.
See also:
setBounds(), getMin(), getMax().
void SbBox2s::getBounds (SbVec2s & boxmin, SbVec2s & boxmax) const [inline]
Returns the box corner points.
See also:
setBounds(), getMin(), getMax().
const SbVec2s & SbBox2s::getMin (void) const [inline] Returns the minimum
point. This should usually be the lower left corner point of the box.
See also:
getOrigin(), getMax().
const SbVec2s & SbBox2s::getMax (void) const [inline] Returns the maximum
point. This should usually be the upper right corner point of the box.
See also:
getMin().
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.
See also:
isEmpty().
SbBool SbBox2s::intersect (const SbVec2s & point) const Check if the given
point lies within the boundaries of this box.
SbBool SbBox2s::intersect (const SbBox2s & box) const Check if box lies
wholly or partly within the boundaries of this box.
void SbBox2s::getOrigin (short & originX, short & originY) const [inline]
Returns the coordinates of the box origin (i.e. the lower left corner).
See also:
getMin().
void SbBox2s::getSize (short & sizeX, short & sizeY) const [inline] Returns
width and height of box.
float SbBox2s::getAspectRatio (void) const [inline] Returns aspect ratio of
box, which is defined as box width divided on box height.
