Creating an output connector for document preview (optional)

To use customized drivers or fonts when previewing documents, you must manually create and select all preview output connectors in the Project.

Note:

You cannot combine default preview connectors with manually created preview connectors in the same Project.

Which output connector?

If you want to use the same driver and settings for preview and output, you can use the same output connector for both preview and output. At a preview service request, the actual connector is not invoked – only the driver is applied.

If you cannot use the same connector, you must create a separate preview output connector. For example, a NULL Connector.

Prerequisites and recommendations

•	Use default preview connectors must be cleared in the Runtime Message settings dialog box. See Service-enabling the Message.

•	In the Platform configuration, output mode Job must be selected and output queues must be configured.

•	For PDF drivers, we recommend that you select Use compression: Yes for performance reasons.

To create a preview output connector

•	Create and configure the output connector using standard procedures.

To select a preview output connector

•	Use the scripting functions below to decide if an invocation is a preview service request. If it is, you can select the appropriate output connector depending on content type.

Scripting function	Description
IsPreview()	Checks if the current job is a preview job.
GetPreviewType()	Returns a number, indicating whether a job is a preview job. If the job is a preview job, the number indicates from where the preview job is invoked.
GetRequestedPreviewContentType()	Only available for preview calls from Ad Hoc Correspondence, Correspondence Reviewer, and Composition Center. Returns a string containing an optionally requested content type for a response to a preview request. The returned value can be used to select an appropriate connector for the preview Process.

For detailed information, see Preview functions in the Scripting Reference.

Example 5

Using scripting to select output connector

IsPreview checks if the current job is a preview job and GetPreviewType returns a number that states that the preview job is invoked from Composition Center. In this case, a NULL Connector named Preview is selected.

if (IsPreview())

{

	   if(GetPreviewType () = 1)

	   {

   		$connector = "Preview";

		   }
