Method Detail

getMimeTypes

public java.lang.String[] getMimeTypes()

Description copied from class: MSOfficeHandler

This method returns the mime types a particular AssetHandler supports.

Specified by:

getMimeTypes in interface AssetHandler

Overrides:

getMimeTypes in class MSOfficeHandler

Returns:

mime type, e.g. image/jpg

getImage

public java.awt.image.BufferedImage getImage(Rendition rendition,
                                             java.awt.Dimension dim)
                                      throws java.io.IOException

Description copied from interface: AssetHandler

This method retrieves the graphical representation of an Assets given Rendition. For images the BufferedImage of the original image is returned, for other formats the first page is retrieved as BufferedImage.

If maxDimension is given, the handler should return an image where no dimension extends the given value. This can be used to reduce the memory footprint of large buffered images if the full resolution is not needed.

Specified by:

getImage in interface AssetHandler

Overrides:

getImage in class MSOfficeHandler

Parameters:

rendition - The rendition for which to retrieve its graphical representation.

dim - optional constraint for the maximal dimension of the image.

Returns:

BufferedImage if a graphical representation exists, otherwise null

Throws:

java.io.IOException - in case an error is thrown while fetching the buffered image

dogetImage

public java.awt.image.BufferedImage dogetImage(Rendition rendition,
                                               java.awt.Dimension dim)
                                        throws java.io.IOException

Throws:

java.io.IOException

canHandleSubAssets

public boolean canHandleSubAssets()

Description copied from class: AbstractAssetHandler

Indicates if the handler supports processing of sub assets

Specified by:

canHandleSubAssets in interface AssetHandler

Overrides:

canHandleSubAssets in class AbstractAssetHandler

Returns:

true if handler is able to process sub assets

processSubAssets

public java.util.List<java.lang.String> processSubAssets(Asset asset)

Description copied from interface: AssetHandler

Handler implementations may choose to support sub asset creation for the file types it handles. The method is called by the CreateSubAssetsProcess during import/update of an asset and its binary, as part of the DAM Update Asset workflow. Sub assets represent fragments of the original asset, for example every page of a multi-page PDF document are sub assets. Sub assets are stored as assets themselves under the parent asset. Sub assets are stored in the subassets folder of the main asset, e.g. at /content/dam/geometrixx/documents/ECM Artikel.pdf/subassets.

The asset argument represents the javax.jcr.Node of type nt:file holding the binary content or the DAM Asset node (type dam:Asset), for which its original rendition would be retrieved.

Specified by:

processSubAssets in interface AssetHandler

Overrides:

processSubAssets in class AbstractAssetHandler

Parameters:

asset - asset to extract sub assets

Returns:

List constaining all paths to the newly created assets
