ipe::Rect::Rect | ( | ) | [inline, explicit] |
Create empty rectangle.
ipe::Rect::Rect | ( | const Vector & | c | ) | [inline, explicit] |
Create rectangle containing just the point c.
Create rectangle containing points c1 and c2.
void ipe::Rect::clear | ( | ) | [inline] |
Make rectangle empty.
int ipe::Rect::isEmpty | ( | ) | const [inline] |
True if rectangle is empty.
double ipe::Rect::left | ( | ) | const [inline] |
Return left side.
double ipe::Rect::right | ( | ) | const [inline] |
Return right side.
double ipe::Rect::bottom | ( | ) | const [inline] |
Return bottom side.
double ipe::Rect::top | ( | ) | const [inline] |
Return top side.
Vector ipe::Rect::topRight | ( | ) | const [inline] |
Return top right corner.
Vector ipe::Rect::bottomLeft | ( | ) | const [inline] |
Return bottom left corner.
Vector ipe::Rect::topLeft | ( | ) | const [inline] |
Return top left corner.
Vector ipe::Rect::bottomRight | ( | ) | const [inline] |
Return bottom right corner.
double ipe::Rect::width | ( | ) | const [inline] |
Return width.
double ipe::Rect::height | ( | ) | const [inline] |
Return height.
void Rect::addPoint | ( | const Vector & | rhs | ) |
Enlarge rectangle to contain point.
void Rect::addRect | ( | const Rect & | rhs | ) |
Enlarge rectangle to contain rhs rectangle.
Does nothing if rhs is empty.
void Rect::clipTo | ( | const Rect & | cbox | ) |
Clip rectangle to fit inside cbox.
Does nothing if either rectangle is empty.
bool Rect::contains | ( | const Vector & | rhs | ) | const |
Does (closed) rectangle contain the point?
bool Rect::contains | ( | const Rect & | rhs | ) | const |
Does rectangle contain other rectangle?
bool Rect::certainClearance | ( | const Vector & | v, |
double | bound | ||
) | const |
Returns false if the distance between the box and v is smaller than bound. Often returns true if their distance is larger than bound.
bool Rect::intersects | ( | const Rect & | rhs | ) | const |
Does rectangle intersect other rectangle?
