The thumbnail view of the library window can show a preview image of documents with a blob
property holding the image data. If you want to do so, you need to register your document type
and configure the name of the blob property you want the thumbnail preview to be generated
from. From ActionScript, use the registerImageDocumentType method of the
IEditorContext. You can also use the standard plug
configureDocumentTypes, setting the imageProperty for a given set of
document types.
This is how the mapping is registered in the editor plugin of CoreMedia Blueprint:
<editor:configureDocumentTypes names="CMPicture,CMImage"
imageProperty="data"/>Example 7.42. Configuring the thumbnail view
The configured property applies to exactly the given document types, only. It is not inherited by subtypes.
