Transformer Parameters

Every transformer contains at least one parameter: the Transformer Name. Most transformers also have additional parameters that you can change to suit your workspace.

Clicking the Properties button to the top right of each transformer displays a dialog that contains defaults that Workbench initially sets for the transformer.

Properties Button Colors

The properties button on a transformer is color-coded to reflect the status of the parameters.

	A blue properties button (or one that matches the color of its transformer) indicates that the default transformer settings have been checked and amended as required, and that the transformer is ready to use.
	A yellow properties button indicates that the default settings have not yet been checked. The transformer can be used in this state, but the results may be unpredictable.
	A red properties button indicates that there is at least one setting for which FME cannot supply a default value. The setting must be provided with a value before the transformer can be used.

In many cases, you can use the transformer without changing the default values; however, sometimes you will need to perform an action before you can use the transformer. In these cases, the transformer parameter will be highlighted red, as shown in the Buffer Amount parameter below:

See Transformer Defaults for information on saving default values.

Transformer Colors

Transformers are all color-coded.

All regular transformers are blue.

You can also create Custom Transformers (see the Workbench Help), which can be green or cyan, depending on whether they are embedded or linked.

Some transformers, such as the Inspector, have their own distinctive icon:
