\space_fold

Description 

\space_fold allows to modify the visual aspect of edges. It changes the blank space of each extremities of an edge. It takes an edge as its first parameter and two integer values matching respectively first and second extremity percentage of space we want to left blank. It can be applied on all kind of folds (mountain, valley, existing fold, border or xray fold), but it has no effect if the edge on which it is applied has been defined with edge limitation (cf. §for example \mountain_fold ).

Usage

  \space_fold([a,c], 40, 40); % fold becomes just a pinch

Formal structure

  \space_fold(EDGE, V1_PERCENTAGE, V2_PERCENTAGE);

Parameters

  EDGE
  Description    : Indicates the modified edge.
  Type           : Edge, couple of vertex identifiers
  Allowed values : Any couple of vertex identifiers already 
                   defined. Physical edge is mandatory.

  V1_PERCENTAGE
  Description    : Indicates the percentage of total edge length we
                   have to left blank close to first vertex of EDGE.
  Type           : Integer.
  Allowed values : Any value.
  
  V2_PERCENTAGE
  Description    : Indicates the percentage of total edge length we
                   have to left blank close to second vertex of EDGE.
