com.day.cq.dam.handler.standard.ps.PostScriptHandler

All Implemented Interfaces:

AssetHandler

public class PostScriptHandler
extends PdfHandler

PostScriptHandler Handles files with mimetype as application/postscript. First it tries to see if the file is an illustrator file then it delegate the handling to pdfHandler else, it tries to use the format handlers that are available for handle the file.

Method Detail

getMimeTypes

public java.lang.String[] getMimeTypes()

This method returns the mime types a particular AssetHandler supports.

Specified by:

getMimeTypes in interface AssetHandler

Overrides:

getMimeTypes in class PdfHandler

Returns:

mime type, e.g. image/jpg

extractMetadata

public final ExtractedMetadata extractMetadata(Asset asset)

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 PdfHandler

Parameters:

asset - The Asset, from whose original binary metadata will extracted.

Returns:

The extracted metadata.

getImage

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

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 PdfHandler

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

processSubAssets

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

Extracts and create sub asset for the asset. For illustrator file, it tries to extract the subassets, for application/postscript files generated from other applications, it is a no-op

Specified by:

processSubAssets in interface AssetHandler

Overrides:

processSubAssets in class PdfHandler

Parameters:

asset - asset to extract sub assets

Returns:

List constaining all paths to the newly created assets

See Also:

AssetHandler.canHandleSubAssets(), Asset.isSubAsset()

processRelated

public java.util.Iterator<? extends AssetRelation> processRelated(Asset asset)

Description copied from class: PdfHandler

extracts and stores the links to the assets related with provided asset.

Specified by:

processRelated in interface AssetHandler

Overrides:

processRelated in class PdfHandler

Parameters:

asset - asset to process

Returns:

Iterator of AssetRelation or an empty iterator if no related assets are available
