Detailed Description

template<typename TKSpace = KhalimskySpaceND<2>>
class DGtal::GridCurve< TKSpace >

Aim: describes, in a cellular space of dimension n, a closed or open sequence of signed d-cells (or d-scells), d being either equal to 1 or (n-1).

For instance, the topological boundary of a simply connected digital set is a closed sequence of 1-scells in 2d.

Template Parameters

TKSpace Khalimsky space, a model of CCellularGridSpaceND

Using the namespace Z2i, defined in StdDefs.h, you can instanciate a grid curve as follows:

  //default construction
  Curve c1; 
 
  //from a Khalimsky space
  K2 ks; ks.init( lowerBound, upperBound, true ); 
  Curve c2( ks ); 

This object provides several IO services. For instance, you can read a grid curve from a data file, which contains the (digital) coordinates of the 0-cells (pointels) in nd:

    fstream inputStream;
    inputStream.open (square.c_str(), ios::in);
    c1.initFromVectorStream(inputStream);
    inputStream.close();

Note that if the first and last 0-scells of the file have the same coordinates (i) or if only one of their coordinates differ by 1 (ii), then the grid curve is considered as closed, ie. scells directly incident to the last signed cell and indirectly incident to the first signed cell are the same.

You can also build a grid curve from the contour of a digital set as follows:

    vector<SCell> contour;                           //contour
    SurfelAdjacency<K2::dimension> sAdj( true );     //adjacency
 
    //tracking and init grid curve
    SCell s = Surfaces<KSpace>::findABel( ks, set, 1000 );
    Surfaces<KSpace>::track2DBoundary( contour, ks, sAdj, set, s );
    c2.initFromSCellsVector( contour );

To save a grid curve in a data file, GridCurve provides the special method writeVectorToStream():

    ofstream outputStream("myGridCurve.dat"); 
    if (outputStream.is_open()) 
      c2.writeVectorToStream(outputStream);
    outputStream.close();

The stream mechanism is used to display the true content of the grid curve:

trace.info() << c1 << std::endl;

DGtal::Trace::info

std::ostream & info()

DGtal::trace

Trace trace

Definition: Common.h:153

In 2d, the grid curve can be drawn in a vector graphics file as follows:

    Board2D aBoard;
    aBoard.setUnit(Board2D::UCentimeter);
    aBoard << c2; 
    aBoard.saveEPS( "myGridCurve.eps", Board2D::BoundingBox, 5000 );

See Board2D: a stream mechanism for displaying 2D digital objects to learn more about the 2d drawing mechanism used in DGtal.

Moreover, this object provides several ranges as nested types:

SCellsRange to iterate over the d-scells
PointsRange to iterate over the digital coordinates of the 0-scells that are directly incident to the d-scells
MidPointsRange to iterate over the real coordinates of the d-scells
ArrowsRange to iterate over the arrows coding the 1-scells. Note that an arrow is a pair point-vector: the point codes the digital coordinates of the 1-scell, the vector gives the topology and sign of the 1-scell.
InnerPointsRange to iterate over the digital coordinates of the n-scells that are directly incident to the (n-1)-scells.
- OuterPointsRange to iterate over the digital coordinates of the n-scells that are indirectly incident to the (n-1)-scells.
IncidentPointsRange to iterate over the pairs of inner and outer points (defined as above)
CodesRange to iterate over the codes {0,1,2,3} of the 1-scells (only available if n = 2)

You can get an access to these eight ranges through the following methods:

Each range can be displayed in the standard output or can be drawn (except CodesRange) in a vector graphics file as shown in the following snippet:

      Curve::IncidentPointsRange r = c1.getIncidentPointsRange(); 
      
      trace.info() << r << endl;
      
      aBoard << SetMode(aDomain.className(), "Grid") << aDomain; 
      aBoard << r; 
      aBoard.saveEPS( "MyIncidentPointsRange.eps", Board2D::BoundingBox, 5000 );

Moreover, each range has the following inner types:

ConstIterator
ConstReverseIterator
ConstCirculator
ConstReverseCirculator

And each range provides these (circular)iterator services:

begin() : begin ConstIterator
end() : end ConstIterator
rbegin() : begin ConstReverseIterator
rend() : end ConstReverseIterator
c() : ConstCirculator
rc() : ConstReverseCirculator

You can use these services to iterate over the elements of a given range as follows:

    trace.info() << "\t iterate over the range" << endl;
    Range::ConstIterator it = r.begin(); 
    Range::ConstIterator itEnd = r.end(); 
    for ( ; it != itEnd; ++it)
    {
      trace.info() << *it;
    }
    trace.info() << endl;
    
    trace.info() << "\t iterate over the range in the reverse way" << endl;
    Range::ConstReverseIterator rit = r.rbegin(); 
    Range::ConstReverseIterator ritEnd = r.rend(); 
    for ( ; rit != ritEnd; ++rit) 
    {
      trace.info() << *rit;
    }
    trace.info() << endl;
      
    trace.info() << "\t iterate over the range in a circular way" << endl;
    Range::ConstCirculator c = r.c();
    //set the starting element wherever you want... 
    for (unsigned i = 0; i < 20; ++i) ++c; 
    //... and circulate
    Range::ConstCirculator cend( c );
    do 
    {
      trace.info() << *c;
      c++;
    } while (c!=cend);
    trace.info() << endl;
