getStrippedTransformOptions

public Map<String,String> getStrippedTransformOptions(Map<String,String> transformOptions)

Returns a subset of the supplied actual transform options from the rendition definition that are known to this transformer. The ones that will be passed to the T-Engine. It strips out extra ones.

Parameters:

transformOptions - the complete set of actual transform options. This will be returned if all options are known to this transformer. Otherwise a new Map is returned.

Returns:

the transformOptions to be past to the T-Engine.
