MAP ​

Adapt the scale and position of following commands or turn this kind of behavior off.

Syntax ​

Scale sizes proportionally:

leo-grammar
MAP [ scale:realValue ] [ transx:measureValue ] [ transy:measureValue ] .

Separate scales for the horizontal and vertical axis:

leo-grammar
MAP [ scalex:realValue ] [ scaley:realValue ] [ transx:measureValue ] [ transy:measureValue ] .

Parameters ​

Parameters for proportional scaling:

  • scale (realValue, optional) - The factor by which all positions and sizes should be multiplied. The default is 1.0.
  • transx (measureValue, optional) - Translation coordinate for horizontal axis. This is added to all x-coordinates. The default is 0cm.
  • transy (measureValue, optional) - Translation coordinate for vertical axis. This is added to all y-coordinates. The default is 0cm.

Parameters for separate axis scaling:

  • scalex (realValue, optional) - The factor by which all positions and sizes of the horizontal axis should be multiplied. The default is 1.0.
  • scaley (realValue, optional) - The factor by which all positions and sizes of the horizontal axis should be multiplied. The default is 1.0.
  • transx (measureValue, optional) - Translation coordinate for horizontal axis. This is added to all x-coordinates. The default is 0cm.
  • transy (measureValue, optional) - Translation coordinate for vertical axis. This is added to all y-coordinates. The default is 0cm.

Details ​

The MAP command makes it possible to scale all following shape commands. A popular application is to resize a complex GraphRep symbol without having to adapt each single coordinate value, like POLYGON with many coordinates.

The scaling can be set proportional (scale) or non-proportional (scalex, scaley). A value of 1.0 or no specified value means original size. Additionally, translation coordinate values can be specified (transx, transy). These values specify a movement of coordinates, which is performed after the scaling.

The MAP settings can be reset, disabling any scaling and translation coordinates, by using the command without any parameters.

Examples ​

Draw four rectangles, each one with a different size and position and a number identifying each rectangle in its middle. The changes to the size and position are realized through different (MAP) settings.
