    Description copied from interface: AssetHandler
    
    This method returns the mime types a particular AssetHandler supports.
    
    Returns:
    
    mime type, e.g. image/jpg
    
    See Also:
    
    AssetHandler.getMimeTypes()
  - extractMetadata
```
public ExtractedMetadata extractMetadata(Asset asset)
```
    Description copied from interface: AssetHandler
    
    This method is used by the com.day.cq.dam.core.process.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 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.
    
    Parameters:
    
    asset - The Asset, from whose original binary metadata will extracted.
    
    Returns:
    
    The extracted metadata.
  - getImage
```
public BufferedImage getImage(Rendition rendition)
                       throws 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
    
    Specified by:
    
    getImage in interface AssetHandler
    
    Overrides:
    
    getImage in class AbstractAssetHandler
    
    Parameters:
    
    rendition - The rendition for which to retrieve its graphical representation.
    
    Returns:
    
    BufferedImage if a graphical representation exists, otherwise null
    
    Throws:
    
    IOException - in case an error is thrown while fetching the buffered image
  - getImage
```
public BufferedImage getImage(Rendition rendition,
                              Dimension maxDimension)
                       throws 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 AbstractAssetHandler
    
    Parameters:
    
    rendition - The rendition for which to retrieve its graphical representation.
    
    maxDimension - 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
