Thumbnail Plug-Ins 

Use

Thumbnail Plug-ins are based on Java classes and enable the generation of preview images for objects of certain MIME types.

 

Integration

The repository manager for thumbnails uses plug-ins stored in the configuration to generate preview images.

 

Prerequisites

●      The Java AWT (java.awt.*) libraries are installed on UNIX systems without X Windows for the plug-in images.

 

●      On UNIX system, the following entry is listed for the headless mode in the Java VM settings:

-Djava.awt.headless=true

You make this setting in the SAP AS Java Engine Config Tool (see SAP Note 710146).

 

Features

The plug-in for creating thumbnails of the data formats jpeg and gif is included in the standard delivery.  If you want to use thumbnails for other file formats, you have to implement your own plug-ins.

The configuration of a plug-in includes the following parameters:

Parameters for Thumbnail Plug-Ins

Parameters	Required	Description
