Description copied from interface: ThumbnailService

Creates a new thumbnail for the given node and content property. The mimetype and transformation options are used to determine the content transformer that will be best suited to create the thumbnail. The thumbnail name is optional, but is usually set to provide an easy way to identify a particular 'type' of thumbnail. Once created the source node will have the 'rn:renditioned' aspect applied and an association to the thumbnail node (of type 'rn:rendition') will be created. The returned node reference is to the 'rn:rendition' content node that contains the thumbnail content in the standard 'cm:content' property.

Specified by:

createThumbnail in interface ThumbnailService

Parameters:

node - the source content node

contentProperty - the content property

mimetype - the thumbnail mimetype

transformationOptions - the thumbnail transformation options

thumbnailName - the name of the thumbnail (optional, pass null for unnamed thumbnail)

Returns:

NodeRef node reference to the newly created thumbnail
