multiLineString abstract method

void multiLineString(Iterable<PositionSeries> lineStrings, { String? name, Box? bounds, })

Writes a multi line string with an array of lineStrings (each with a chain of positions).

Use an optional name to specify a name for a geometry (when applicable).

An optional bounds can used set a minimum bounding box for a geometry written. A writer implementation may use it or ignore it.

An example to write a multi line string with two line strings:

 content.multiLineString(
     // an array of chains (one chain for each line string)
     [
       // a chain as a flat structure with four (x, y) points
       [
         10.1, 10.1,
         5.0, 9.0,
         12.0, 4.0,
         10.1, 10.1,
       ].positions(Coords.xy),
       // a chain as a flat structure with three (x, y) points
       [
         -1.1, -1.1,
         2.1, -2.5,
         3.5, -3.49,
       ].positions(Coords.xy),
     ],
 );

Implementation

void multiLineString(
  Iterable<PositionSeries> lineStrings, {
  String? name,
  Box? bounds,
});
