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.

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().

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().

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::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 wholly or partly within the boundaries of this 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.

float SbBox2i32::getAspectRatio (void) const [inline]

Returns aspect ratio of box, which is defined as box width divided on box height.
