\visible_area_height

Description 

\visible_area_height allows user to define the vertical limit for steps clipping box. It takes only one parameter which is the length in millimeter. This operator can be found in several different locations :

• inside the header block (initial global)
• between step blocks (new global)
• inside step blocks (local)

First location is inside the global diagram information block, the scope of the operator is global. It can be seen as the set of a default value. If \visible_area_height is found between two step blocks, it means that the possible default value defined in the header block is now replace by its value. Finally, if the operator is found inside a step block this specified the local change of the height of this step. Next steps height will be different according to the previous value globally defined.

Usage

  \diagram_header{
    ....
    \visible_area_height(100); % global default step height value of 10cm
    ....
  }
    ....

  \step {
    ....
    \visible_area_height(150); % this step needs a wider vertical
                               % limit than default
    ....
  }

  \visible_area_height(80); % now we can reduce next steps height 

  \step {  
    ....  % height of this step is 8cm (same for nexts)
  }

Formal structure

  \visible_area_height(HEIGHT);

Parameters
