MapboxStyler

Creates a common style for a group of features destined for the GeoJSON writer.

The example below shows a polygon styled by MapboxStyler.

For more information regarding GeoJSON Mapbox styling:

  • See the FME GeoJSON Writer chapter in the FME Readers and Writers manual (in FME Workbench, select Help > FME Readers and Writers Reference)

    See the SimpleStyle documentation: https://github.com/mapbox/simplestyle-spec

Configuration

Parameters

Title

This parameter specifies the title to be displayed when the output feature is clicked or hovered over.

Description

This parameter specifies the description to be displayed when the output feature is clicked or hovered over.

Marker Size

This parameter specifies the size of the selected marker symbol. If “small” is selected, a 12x12 pixel marker is displayed. “Medium” represents 18x18 pixels, and “large” represents 24x24 pixel markers.

Marker Symbol

Marker symbol specifies the name of an icon selected from the icon picker, or a valid icon name from the mapbox-maki icon collection found here. The marker symbol is overlaid inside the marker.

Marker Color

This parameter specifies the color of the marker displayed.

Specifying Colors

Colors may be entered directly or chosen from the color picker via the ellipsis button.

Colors can be specified by RGB values or hex codes. RGB values may be either 24-bit or decimal (0 - 1). If the value type is unclear, as in (1,1,1), the 24-bit interpretation is used. Hex codes are accepted with or without a hash sign (#).

Stroke Color

This parameter specifies the pen color of the feature used to render the feature in the set color. The pen color determines the color of lines, and area boundaries.

Specifying Colors

Colors may be entered directly or chosen from the color picker via the ellipsis button.

Colors can be specified by RGB values or hex codes. RGB values may be either 24-bit or decimal (0 - 1). If the value type is unclear, as in (1,1,1), the 24-bit interpretation is used. Hex codes are accepted with or without a hash sign (#).

Stroke Opacity

Stroke opacity specifies the opacity of the pen color of the feature. A value of 1.0 is fully opaque, and 0.0 is completely transparent.

Stroke Width

Line Width specifies the width of line geometries and boundaries of area geometries.

Polygon Fill Color

This parameter specifies the fill color for an area geometry on a feature used to render the interior feature in the set color.

Specifying Colors

Colors may be entered directly or chosen from the color picker via the ellipsis button.

Colors can be specified by RGB values or hex codes. RGB values may be either 24-bit or decimal (0 - 1). If the value type is unclear, as in (1,1,1), the 24-bit interpretation is used. Hex codes are accepted with or without a hash sign (#).

Editing Transformer Parameters

Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click beside the applicable parameter.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters.

Using the Text Editor

The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.

Text Editor

Using the Arithmetic Editor

The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.

Arithmetic Editor

Conditional Values

Set values depending on one or more test conditions that either pass or fail.

Parameter Condition Definition Dialog

Content

Expressions and strings can include a number of functions, characters, parameters, and more.

When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.

String Functions

These functions manipulate and format strings.

Special Characters

 A set of control characters is available in the Text Editor.

Math Functions

Math functions are available in both editors.
Date/Time Functions Date and time functions are available in the Text Editor.

Math Operators

These operators are available in the Arithmetic Editor.

FME Feature Functions

These return primarily feature-specific values.

FME Parameters

FME and workspace-specific parameters may be used.
Creating and Modifying User Parameters Create your own editable parameters.

Table Tools

Transformers with table-style parameters have additional tools for populating and manipulating values.

Row Reordering

Enabled once you have clicked on a row item. Choices include:

  • Add a row
  • Remove a row
  • Move current row up one
  • Move current row down one
  • Move current row to top
  • Move current row to bottom

Cut, Copy, and Paste

Enabled once you have clicked on a row item. Choices include:

  • Cut a row - delete and copy to clipboard
  • Copy a row to the clipboard
  • Paste a row from the clipboard

Cut, copy, and paste may be used within a transformer, or between transformers.

Filter

Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output.

Import

Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers.

Reset/Refresh

Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers.

Note: Not all tools are available in all transformers.

For more information, see Transformer Parameter Menu Options.
