Method Detail

extractMetadata

public ExtractedMetadata extractMetadata(Asset asset)

Description copied from class: AbstractAssetHandler

This method is used by the ExtractMetadataProcess as part of the DAM Update Asset workflow during import or update of an asset. Implementations must return an ExtractedMetadata object, which may be empty if no metadata is extracted, or contains the metadata values extracted from the binary being imported/updated at the time. The ExtractMetadataProcess will later save the metadata contained in ExtractedMetadata to the asset's metadata node (e.g. /content/dam/geometrixx/banners/banner-mono.png/jcr:content/metadata). Implementations are free to decide which and how many metadata values are extracted.

The method 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:

extractMetadata in interface AssetHandler

Overrides:

extractMetadata in class AbstractAssetHandler

Parameters:

asset - the file node

Returns:

all extracted metadata

Asset.getMetadata(), Asset.getMetadata(String), Asset.getMetadataValue(String)

getImage

public BufferedImage getImage(Rendition rendition)
                       throws IOException

Description copied from class: AbstractAssetHandler

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

Specified by:

getImage in interface AssetHandler

Overrides:

getImage in class AbstractAssetHandler

Parameters:

rendition - to retrieve the image representation

Returns:

BufferedImage if a graphical representaion exists, otherwise null

Throws:

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

getImage

public BufferedImage getImage(Rendition rendition,
                              Dimension dim)
                       throws 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 AbstractAssetHandler

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:

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

getMimeTypes

public String[] getMimeTypes()

This method returns the mime types a particular AssetHandler supports.

Returns:

mime type, e.g. image/jpg
