Document previewing In Composer, users can preview how the output documents are presented with imported texts and images. Since no input data is available when previewing, sample files with sample data must be available. If metadata is used in texts or in conditions of rules, users can also enter metadata values in Composer to simulate different scenarios. For example, to simulate how different marketing messages are presented for different customer categories. Document preview should be managed by a separate StreamServer application. In the Project, you must configure the following: • A Preview input connector that receives incoming preview requests via HTTP. • A HTTP Response output connector that responds to the request by generating documents for preview. • At least one sample file for each document type to be previewed in Composer. Sample project A sample Project for document preview is provided with the StreamServe setup.
