• GRID_SIZE: When interpolating the graph solution to generate the isochrone, number of subdivisions along the x axis when building the grid (the y is computed using the aspect ratio of the output image). The default value is '100'.
• COLOR_ISOLINES: Color each isoline according to the colormap; otherwise, use the foreground color. Supported values:
  • TRUE
  • FALSE
  The default value is TRUE.

  • TRUE
  • FALSE
  The default value is FALSE.

• LABELS_FONT_FAMILY: When add_labels is set to true, font name to be used when adding labels. The default value is 'arial'.
• LABELS_SEARCH_WINDOW: When add_labels is set to true, a search window is used to rate the local quality of each isoline. Smooth, continuous, long stretches with relatively flat angles are favored. The provided value is multiplied by the labels_font_size to calculate the final window size. The default value is '4'.
• LABELS_INTRALEVEL_SEPARATION: When add_labels is set to true, this value determines the distance (in multiples of the labels_font_size) to use when separating labels of different values. The default value is '4'.
• LABELS_INTERLEVEL_SEPARATION: When add_labels is set to true, this value determines the distance (in percent of the total window size) to use when separating labels of the same value. The default value is '20'.
• LABELS_MAX_ANGLE: When add_labels is set to true, maximum angle (in degrees) from the vertical to use when adding labels. The default value is '60'.

The default value is an empty Map.

Returns:

this to mimic the builder pattern.

getOptions

Returns:

Additional parameters

• SOLVE_TABLE: Name of the table to host intermediate solve results containing the position and cost for each vertex in the graph. If the default value is used, a temporary table is created and deleted once the solution is calculated. The default value is ''.
• IS_REPLICATED: If set to true, replicate the solve_table. Supported values:
  • TRUE
  • FALSE
  The default value is TRUE.
• DATA_MIN_X: Lower bound for the x values. If not provided, it will be computed from the bounds of the input data.
• DATA_MAX_X: Upper bound for the x values. If not provided, it will be computed from the bounds of the input data.
• DATA_MIN_Y: Lower bound for the y values. If not provided, it will be computed from the bounds of the input data.
• DATA_MAX_Y: Upper bound for the y values. If not provided, it will be computed from the bounds of the input data.
• CONCAVITY_LEVEL: Factor to qualify the concavity of the isochrone curves. The lower the value, the more convex (with '0' being completely convex and '1' being the most concave). The default value is '0.5'.
• USE_PRIORITY_QUEUE_SOLVERS: sets the solver methods explicitly if true Supported values:
  • TRUE: uses the solvers scheduled for 'shortest_path' and 'inverse_shortest_path' based on solve_direction
  • FALSE: uses the solvers 'priority_queue' and 'inverse_priority_queue' based on solve_direction
  The default value is FALSE.
• SOLVE_DIRECTION: Specify whether we are going to the source node, or starting from it. Supported values:
