5.1.1.6. Blob Editors

The following editors are available for blob fields:

Class	Description
AggregatingImageBlobEditor	This editor displays blobs of type image/gif, image/png or image/jpeg in the property as an image. In addition, you can define other properties which contain scaled versions of the blob. This blobs will be computed from the original blob by the CoreMedia Server. The size and type of the scaled images is defined in the `imageconverter.properties` file. The property `defaultExtension` in `imageconverter.properties` 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 of the `imageconverter.properties` file. `originalProperty="<PropertyName>"`: Sets the name of the property which should be converted when the blob contained in the property of the AggregatingImageBlobEditor changes. `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 of the `imageconverter.properties` file. Example: `<Document type="Photo">` `<Property name="ScannedPhoto" editorClass="AggregatingImageBlobEditor" thumbnailProperty="Preview" onlineProperty="Online"/>` `</Document>`
BasicBlobEditor	Generic editor which only displays blob size and content type. Files from the file system can be loaded and saved. Using the property `WebDAVUriPrefix`, the blob can be opened directly in the associated WebDAV application. For this, the property has to be set to the URL prefix for the WebDAV server. If a prefix like `http://Server:8001/webdav/` is used on a blob in a document `/Inbox/Test.doc,` then an URL `http://Server:8001/webdav/Inbox/Test.doc` for WebDAV lookup is used.
ImageBlobEditor	Displays blobs of type image/gif, image/png or image/jpeg as an image. If the size of an image exceeds the document window size, it will be scaled down. You can use the attribute `imageScaledForDisplay="false"` to disable the behavior.
TextBlobEditor	Allows editing of blobs of type text/* in a text field.
