Detailed Description

The SbBox2i32 class is a 2 dimensional box with 32-bit integer coordinates. This box class is used by other classes in Coin for data exchange. It provides storage for two box corners with 32-bit integer coordinates, which is among other things useful for representing screen or canvas areas in absolute window coordinates.

Constructor & Destructor Documentation

  SbBox2i32::SbBox2i32 (void) [inline]
The default constructor makes an empty box.

  SbBox2i32::SbBox2i32 (int32_t xmin, int32_t ymin, int32_t xmax, int32_t 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.

  SbBox2i32::SbBox2i32 (const SbVec2i32 & minpt, const SbVec2i32 & maxpt) [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.

  SbBox2i32::SbBox2i32 (const SbBox2s & box) [inline], [explicit]
Constructs an SbBox2i32 instance from the value in an SbBox2s instance.

Since
    Coin 2.5

  SbBox2i32::SbBox2i32 (const SbBox2f & box) [inline], [explicit]
Constructs an SbBox2i32 instance from the value in an SbBox2f instance.

Since
    Coin 2.5

  SbBox2i32::SbBox2i32 (const SbBox2d & box) [inline], [explicit]
Constructs an SbBox2i32 instance from the value in an SbBox2d instance.

Since
    Coin 2.5

Member Function Documentation

  SbBox2i32 & SbBox2i32::setBounds (int32_t xmin, int32_t ymin, int32_t xmax, int32_t 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().

  SbBox2i32 & SbBox2i32::setBounds (const SbVec2i32 & boxmin, const SbVec2i32 & 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().

  SbBox2i32 & SbBox2i32::setBounds (const SbBox2s & box)
Reset the boundaries to the boundaries of the given box.

Returns reference to self.

See also
    getBounds()

  SbBox2i32 & SbBox2i32::setBounds (const SbBox2f & box)
Reset the boundaries to the boundaries of the given box.

Returns reference to self.

See also
    getBounds()

  SbBox2i32 & SbBox2i32::setBounds (const SbBox2d & box)
Reset the boundaries to the boundaries of the given box.

Returns reference to self.

See also
    getBounds()

  void SbBox2i32::getBounds (int32_t & xmin, int32_t & ymin, int32_t & xmax, int32_t & ymax) const [inline]
Returns the box boundary coordinates.

See also
    setBounds(), getMin(), getMax().

  void SbBox2i32::getBounds (SbVec2i32 & boxmin, SbVec2i32 & boxmax) const [inline]
Returns the box corner points.

See also
    setBounds(), getMin(), getMax().

  const SbVec2i32 & SbBox2i32::getMin (void) const [inline]
Returns the minimum point. This should usually be the lower left corner point of the box.

See also
    getOrigin(), getMax().

  SbVec2i32 & SbBox2i32::getMin (void) [inline]
Returns a modifiable reference to the minimum point.

  const SbVec2i32 & SbBox2i32::getMax (void) const [inline]
Returns the maximum point. This should usually be the upper right corner point of the box.

See also
    getMin().

  SbVec2i32 & SbBox2i32::getMax (void) [inline]
Returns a modifiable reference to the maximum point.

  void SbBox2i32::extendBy (const SbVec2i32 & 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 SbBox2i32::extendBy (const SbBox2i32 & box)
Extend the boundaries of the box by the given box parameter. This is equal to calling extendBy() twice with the corner points.

  void SbBox2i32::makeEmpty (void)
Marks this as an empty box.

See also
    isEmpty().

  SbBool SbBox2i32::isEmpty (void) const [inline]
Check if this has been marked as an empty box.

See also
    makeEmpty().

  SbBool SbBox2i32::hasArea (void) const [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).

  SbBool SbBox2i32::intersect (const SbVec2i32 & point) const
Check if the given point lies within the boundaries of this box.

  SbBool SbBox2i32::intersect (const SbBox2i32 & box) const
Check if box lies entirely or partially within the boundaries of this box.

  SbVec2i32 SbBox2i32::getCenter (void) const [inline]
Returns the center point of the box.

  void SbBox2i32::getOrigin (int32_t & originX, int32_t & originY) const [inline]
Returns the coordinates of the box origin (i.e. the lower left corner).

See also
    getMin().

  void SbBox2i32::getSize (int32_t & sizeX, int32_t & sizeY) const [inline]
Returns width and height of box.

  SbVec2i32 SbBox2i32::getSize (void) const [inline]
Returns width and height of box as a 2D vector.

Since
    Coin 3.0

  float SbBox2i32::getAspectRatio (void) const [inline]
Returns aspect ratio of box, which is defined as box width divided by box height.
