Graphic2d_InfiniteLine (const Handle< Graphic2d_GraphicObject > &aGraphicObject, const Quantity_Length X, const Quantity_Length Y, const Quantity_Length DX, const Quantity_Length DY) | |
Creates an infinite line. The reference point is <X>, <Y>. The slope is <DX>, <DY>. Warning: Raises InfiniteLineDefinitionError if the <DX> and <DY> are null. | |
void | Reference (Quantity_Length &X, Quantity_Length &Y) const |
returns the coordinates of the reference point | |
void | Slope (Quantity_Length &dX, Quantity_Length &dY) const |
returns the slope <dX>, <dY> | |

void | Draw (const Handle< Graphic2d_Drawer > &aDrawer) |
Draws the infinite line <me>. | |
Standard_Boolean | Pick (const Standard_ShortReal X, const Standard_ShortReal Y, const Standard_ShortReal aPrecision, const Handle< Graphic2d_Drawer > &aDrawer) |
Returns Standard_True if the infinite line <me> is picked, Standard_False if not. |
