Class Description
AggregatingImageBlobEditor

This blobs will be computed from the original blob by the CoreMedia Server. The property defaultExtension defines the type of the scaled image. jpeg for example would create a JPEG image, see the ImageMagick documentation for all supported formats. You can use the following attributes to define scaled versions of the blob:

  • onlineProperty="<PropertyName>": Sets the name of the property which should be converted when the blob contained in the property of the AggregatingImageBlobEditor changes. The size of the image is defined with the onlineWidth and onlineHeigth properties.

  • thumbnailProperty="<PropertyName>":Sets the name of the property which should be converted when the blob contained in the property of the AggregatingImageBlobEditor changes. The size of the image is defined with the thumbnailWidth and thumbnailHeight properties.
