The transformer gallery is the obvious place to start looking for transformers. There are a number of ways in which transformers here can be located.

Transformer Categories

Transformer categories are a good starting point from which to explore the transformer list. Transformers are grouped in categories to help find a transformer relevant to the problem at hand.

All transformers were re-categorized for 2017. Some long-existing categories were dropped and some new ones created. Altogether, the chosen categories are a better reflection of what a transformer affects, are less ambiguous that previous categories, and are better synchronized with categories in other FME resources such as the Knowledge Centre.

Although all of them are important, the most commonly used transformers are found in these categories:

  • Attributes: Operations for attribute/list management
  • Calculated Values: Operations that return a calculated value
  • Filters and Joins: Operations for dividing and merging data flows
  • Geometries: Operations that create geometry or transform it to a different geometry type
  • Spatial Analyses: Operations that return the result of a spatial analysis
  • Strings: Operations that manipulate string contents, including dates

Simply click on the expand button to show all transformers within a particular category.

Transformer Help

The FME Workbench Help tool displays information about transformers. Simply click on a transformer and press the F1 key to open the help dialog.

This tool is linked to FME Workbench so that a transformer selected (in the gallery or on the canvas) triggers content to display in the Help tool.

Another useful - and printable - piece of documentation is the FME Transformer Reference Guide.
