| gp_XY | CornerMin () const |
| Query a box corner: (Center - HSize). You must make sure that the box is NOT VOID (see IsVoid()), otherwise the method returns irrelevant result. More... | |
| gp_XY | CornerMax () const |
| Query a box corner: (Center + HSize). You must make sure that the box is NOT VOID (see IsVoid()), otherwise the method returns irrelevant result. More... | |

| Standard_Boolean | IsIn (const Bnd_B2d &theBox) const |
| Check that the box 'this' is inside the given box 'theBox'. Returns True if 'this' box is fully inside 'theBox'. More... | |
| Standard_Boolean | IsIn (const Bnd_B2d &theBox, const gp_Trsf2d &theTrsf) const |
| Check that the box 'this' is inside the given box 'theBox' transformed by 'theTrsf'. Returns True if 'this' box is fully inside the transformed 'theBox'. More... | |
| void | SetCenter (const gp_XY &theCenter) |
| Set the Center coordinates. More... | |
| void | SetHSize (const gp_XY &theHSize) |
| Set the HSize (half-diagonal) coordinates. All components of theHSize must be non-negative. More... | |
