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.SYNOPSIS¶

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.

Constructor & Destructor Documentation¶
SbBox2s::SbBox2s (void) [inline]¶
The default constructor makes an empty box.SbBox2s::SbBox2s (shortxmin, shortymin, shortxmax, shortymax) [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 (shortxmin, shortymin, shortxmax, shortymax) [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.Friends And Related Function Documentation¶
int operator== (const SbBox2s &b1, const SbBox2s &b2) [related]¶
Check b1 and b2 for equality.int operator!= (const SbBox2s &b1, const SbBox2s &b2) [related]¶
Check b1 and b2 for inequality.Author¶
