Rendition service
Supported formats
The ImageMaster rendition service is internally used by the WorkplaceClient for several actions concerning document previews, like the following:

to generate and display thumbnail images

Thumbnail processing
For better performance a thumbnail can be integrated into an ImageMaster document (per content object in a revision). If no thumbnail is integrated, the service generates one on the fly from one of the supported formats listed above.
The rendition service checks if a thumbnail is integrated in either of these ways:
-
by an additional file (binary object) with the content property “ima:client:thumbnailOf”
-
by an additional file with the file extension “.thumb”
If both of the above are present, the file marked with the property is selected.
The recommended formats to use for integrating a thumbnail are JPG and PNG. (Also supported but not recommended are BMP and GIF.)
Instead of the above internal processing, the whole mechanism can be replaced by a customer-specific solution.
