The SbBox2i32 class is a 2 dimensional box with int32_t coordinates.
This box class is used by other classes in Coin for data exchange. It provides storage for two box corners with int32_t coordinates.
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 a box with coordinates from box, converting the coordinates to 32-bit integers
SbBox2i32::SbBox2i32 | ( | const SbBox2d & | box | ) | [inline, explicit] |
Constructs a box with coordinates from box, converting the coordinates to 32-bit integers
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.
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.
SbBox2i32 & SbBox2i32::setBounds | ( | const SbBox2s & | box | ) |
Reset the boundaries to the boundaries of the given box.
Returns reference to self.

References SbVec2i32::setValue().
Referenced by extendBy().
void SbBox2i32::extendBy | ( | const SbBox2i32 & | box | ) |
