\scale

Description 

\scale is a zooming operator. It allows to increase (or decrease) the displayed vertices coordinates. It does not modify internal coordinates, it operates only on display. The value following the operator represents the percentage the original size.

This operator can be found in different places :

• inside step blocks (local)
• between step blocks (global)

If \scale is written inside a step block, the scaling factor defined by this operator is only applied for the current step. In the other case, if it is specified between two step blocks, the scaling factor becomes global, it is applied on all next steps. Local scaling operator is always prioritary, if a global scaling factor has been defined before the current step, the local scaling factor is applied for this step as if any global scaling operator was found, but the global value is restored for next steps. The caling factor is an absolute value. Thus, at any moment if we want to restore the default size for next steps, the 100 value can be used in a global operator.

Usage

  \step {
    ....
    \scale(50);  % make this step be drawn twice smaller than normal ones
    ....
  }

  \scale(200); % next steps will displayed twice taller than default
  
  \step {  
    ....  % this step is taller
  }
 
  \step {
    ....
    \scale(100);  % make this only step be drawn as default
    ....
  }

Formal structure

  \scale(FACTOR);
