Detailed Description

DXF circle entity class.

Constructor & Destructor Documentation

◆ MyDXFCircle() [1/2]

MyDXFCircle::MyDXFCircle ( )
inline

Default constructor.

◆ MyDXFCircle() [2/2]

MyDXFCircle::MyDXFCircle ( class MyDXFFile *  dxf)

Construct circle entity by reading from DXF file.

◆ ~MyDXFCircle()

virtual MyDXFCircle::~MyDXFCircle ( )
inlinevirtual

Virtual destructor.

Member Function Documentation

◆ center()

Vec3D MyDXFCircle::center ( void  ) const
inline

Get center point of circle.

◆ copy()

virtual MyDXFCircle* MyDXFCircle::copy ( void  ) const
inlinevirtual

Get a new copy of entity.

Implements MyDXFEntity.

◆ debug_print()

void MyDXFCircle::debug_print ( std::ostream &  os) const
virtual

Print debugging information to stream os.

Implements MyDXFEntity.

◆ end()

virtual Vec3D MyDXFCircle::end ( void  ) const
inlinevirtual

Get end point of path entity.

Implements MyDXFPathEntity.

◆ explode()

void MyDXFCircle::explode ( class MyDXFEntities *  ent,
MyDXFFile *  dxf,
const Transformation *  t 
) const
virtual

Explode into entities.

Break entity into atomic entities and tranform entities them with tranformation t. Add the tranformed entities to the database ent.

Implements MyDXFEntity.

◆ geom_same()

bool MyDXFCircle::geom_same ( const MyDXFCircle &  circle,
double  eps = 1.0e-6 
) const

Check if two entities are geometrically same.

Checks if entity a is the geometrically same as entity b within error limit eps.

◆ get_bbox()

void MyDXFCircle::get_bbox ( Vec3D &  min,
Vec3D &  max,
const class MyDXFFile *  dxf,
const Transformation *  t 
) const
virtual

Return bounding box of entity.

Implements MyDXFEntity.

◆ get_type()

virtual EntityType MyDXFCircle::get_type ( void  ) const
inlinevirtual

Get entity type.

Implements MyDXFEntity.

◆ plot()

void MyDXFCircle::plot ( const class MyDXFFile *  dxf,
cairo_t *  cairo,
const Transformation *  t,
const double  range[4] 
) const
virtual

Plot entity with cairo.

Plot the entity using the transformation from from the object space to cairo coordinates. The visible range is specified by range (xmin,ymin,xmax,ymax) in cairo coordinates.

Implements MyDXFEntity.

◆ radius()

double MyDXFCircle::radius ( void  ) const
inline

Get radius of circle.

◆ ray_cross()

int MyDXFCircle::ray_cross ( double  x,
double  y 
) const
virtual

Check for ray crossing.

Check if ray going from point (x,y) downwards (negative y direction) crosses the entity. Return 1 if crosses odd number of times and 0 if even number of times. Return 2 in case of exact crossing at boundaries. This function is used as a subroutine to inside_loop().

Implements MyDXFPathEntity.

◆ rotate_z()

void MyDXFCircle::rotate_z ( class MyDXFFile *  dxf,
double  a 
)
virtual

Rotate entity around origin.

Rotate for a radians.

Implements MyDXFEntity.

◆ scale()

void MyDXFCircle::scale ( class MyDXFFile *  dxf,
double  s 
)
virtual

Scale entity by factor s.

Implements MyDXFEntity.

◆ set_center()

void MyDXFCircle::set_center ( const Vec3D &  c)

Set center point of circle.

◆ set_end()

virtual void MyDXFCircle::set_end ( const Vec3D &  e)
inlinevirtual

Set end point of path entity.

Implements MyDXFPathEntity.

◆ set_radius()

void MyDXFCircle::set_radius ( double  r)

Set radius of circle.

◆ set_start()

virtual void MyDXFCircle::set_start ( const Vec3D &  s)
inlinevirtual

Set start point of path entity.

Implements MyDXFPathEntity.

◆ start()

virtual Vec3D MyDXFCircle::start ( void  ) const
inlinevirtual

Implements MyDXFPathEntity.

◆ translate()

void MyDXFCircle::translate ( class MyDXFFile *  dxf,
const Vec3D &  dx 
)
virtual

Translate entity by dx.

Implements MyDXFEntity.

◆ write()

void MyDXFCircle::write ( class MyDXFFile *  dxf,
std::ofstream &  ostr 
)
virtual

Write dxf file to stream.

Implements MyDXFEntity.
